Protecting Your HVAC System During Hurricane Season

Thursday, August 25th, 2022

Hurricane season 2022 is well underway. The Carolinas are often impacted by tropical storms, and this year looks to be no different with Colin already bringing the rain. Unless you’re new to Charleston and the Lowcountry, you know now is the time to start preparing for the next big storm, and we’re here to help with some advice on a subject that’s near and dear to us… protecting your HVAC system! Here are 3 quick tips that should help your HVAC unit make it through this year’s storms and hurricanes in great shape.

Hurricane Season 2022

So let’s say the NOAA and local authorities have made the call and it’s time to evacuate. Here are 3 things you should do before you head out:

Cut the Juice

Before you leave, head over to your breaker box. You’ll want to shut off the breaker that powers your HVAC-  and really any other appliances that you won’t need while you’re gone. Cutting the live current to your appliances greatly reduces the risk of them being fried by power surges, shorts, and lightning strikes. This will also protect them from damage when the electrical company is tinkering with downed power lines.

When you return home, be sure that your house isn’t flooded or damaged before flipping your breakers back on.

Clean Up Loose Objects

Be sure to clean up the area around your HVAC unit before heading out. The hurricane winds generated by tropical storms can turn any object bigger than a few pounds into something that can greatly damage your HVAC unit – and the rest of your home. A quick cleanup of things like yard chairs, planters, toys, firewood for the firepit, and tools for the yard can save you a ton of money.

Cover Your Unit

One of the best things you can do for your HVAC unit is cover it with a tight fitting protective cover. Almost every HVAC company out there sells purpose-built weather covers for their HVAC units, and there are generic options as well. We think it’s well worth the investment!

If you already have a tight cover for your unit, be sure to use it, and secure it tightly. If you’re lucky enough to have your system elevated off the ground, that’s even better and should help it avoid any potential flooding. You can also board up your system after you turn it off for even more protection.

Stay Safe During Hurricane Season!

Following each of these simple steps each time there’s a big storm can save you a ton of money… but what’s most important is your safety. If your system is broken after a storm, don’t try to fix it yourself – instead, give the pros at Carolina Climate Control a ring.

Stay safe out there, Charleston!

5 Important HVAC Questions To Consider When Living In Charleston

Thursday, May 12th, 2022

Charleston is one of the best places to live here in America and according to some sources, it’s the actually the best.

Considering all of the beautiful sites, great restaurants and other attractions in the area, it’s not hard to see why we’re one of the fastest growing areas in the US, in terms of people moving into the Lowcountry.

If you happen to be one of those people moving into the greatness that is the Charleston area, most likely HVAC and air conditioning aren’t high on your priority list. However, with our hottest months upon us (as they do every year), you’re going to want to at least put HVAC on your radar for your to-do list.

Even if you’ve been living in Charleston for some time and haven’t really thought about your home comfort and air conditioning, odds are good that the time will come that you’ll definitely need to; often major breakdowns occur during the worst times in the summer.

We know that HVAC might be a bit of a buzz-kill for you as there are so many wonderful things you should be thinking about, so to help you make this process quick, we’ve compiled 5 of the most important questions (and answers) for you to review that will help you get back to the more fun things in life.

1. Should You Try Ductless Air Conditioning In Your Home?

What is ductless air conditioning? It’s slowly becoming one of the more popular HVAC options for homeowners here in Charleston, especially those with older homes or those that are adding additions onto their home that are hard to tap into their current ductwork.

Essentially ductless air conditioning is exactly how it sounds — it’s air conditioning/heating areas of your home without the need to use your air ducts. A ductless unit is placed in a room or other living area on the wall that is attached to an outdoor unit (with conduit). This ductless unit then can be set at your desired temperature using a remote control. Since your system isn’t trying to “push” air through your air duct network, they generally run much more efficiently than traditional central air conditioners and give you more granular control over comfort for each area in your home.

As mentioned above, these are incredibly handy for cooling/heating areas of your home that don’t currently have access to your ductwork or if you plan on adding onto your home and your current ductwork is hard to tap into. Also these are excellent for pool houses, garages and in rooms where you need added control over heating/cooling (you might have a particular “warm” room or “cold” room, for example).

They are engineered with a sleek design that come in a few different colors so that you can match it to your current interior design motif. Also they operate quietly, often quieter than older, traditional units (you probably can hear when your older unit “kicks on” when operating.

So is ductless air conditioning right for your home? If you think you can take advantage or would benefit from the features listed above, then we think that ductless is a great match for your Charleston home.

2. Should You Go With A Traditional Central Air Conditioning System Or A Heat Pump?

For many people moving from colder climates, coming to South Carolina might be the first time you hear the term “heat pump” used when referring to a home’s HVAC system. So what is a heat pump and how does it differ from a traditional central air conditioner?

One the surface, heat pumps function exactly how traditional air conditioners work: they take the air in your home, condition/cool it, and return it into your home.

Heat pumps however add the extra function of being able to warm your home during the colder months here in the Lowcountry. They’re able to draw the warmth from the air outside and use it to warm your interior. Heat pumps don’t generally work very well when temperatures hit extreme lows, however here in South Carolina since the temperatures don’t dip very far (except for those odd winters that happen once every 30 years), a heat pump is more that suffice to keep you warm in the winter time.

Because of the duality of its operation, a heat pump can save you from needing extra heating components & operation (they simply transfer the heat instead of creating it saving you money also), so they’re one of the most common types of units you’ll see around in Charleston.

If you prefer the traditional setup of an air conditioner/furnace HVAC arrangement, then a heat pump might not be right for you.

Otherwise, if you want to save some money and have a heat pump at your disposal for year-round operation, then getting a heat pump would be perfect for your Lowcountry home.

3. Is Getting A High-Efficiency HVAC System Worth It Here?

We’ll be quick with the answer to this question. If you’re looking to save money on your monthly power bills, then a high-efficiency model is the best way to do this.

With the hot, extended summers here in Charleston, operating expenses that your HVAC system will tally will make up a large part of your electricity bills. Thus if you have a high-efficiency system, you’ll generally expect to pay less each month for those bills.

We’ve seen energy bills drop by as much as nearly one-third to one-half after installing high-efficiency systems. They are generally more expensive, however if you’re cutting your monthly power bills down by that much each month, recouping that initial investment goes pretty quickly, especially in the heat of the Lowcountry.

4. Is An HVAC Maintenance Plan Important For My System In Charleston?

Every HVAC system you’ll encounter has a particular lifespan — just like any mechanical device. And just like any other piece of machinery you own (like your car, for example), regular maintenance is needed to not only extend the lifespan of your system, but also keep it running with the highest efficiency.

Plain and simple, signing up for an HVAC maintenance plan is a smart move, no matter where your HVAC system lies in it’s lifespan. Since maintenance plans generally include bi-annual inspections (winter and summer), finding and resolving problems before they become large problems becomes much easier.

Maintenance plans can also include reduced cost repairs, priority scheduling and more features that will benefit you in case of an emergency breakdown.

As mentioned earlier, the summer months can be brutal here in Charleston, not just on yourself but also on your system. Having a maintenance plan in place is best way to keep your system running in tip-top shape when the temperatures start rising.

5. What Is The Best HVAC Company In Charleston?

There are several things to consider when determining the best HVAC company for your home in the Lowcountry. Here are a few of those factors:

  • 1. Licensing and Insurance: make sure your company has both in place and current.
  • 2. N.A.T.E. Certification: North American Technician Excellence certification; this ensures you get top-notch, well trained techs working on your system.
  • 3. Good Reviews: check Facebook, Google, Yelp, et. al. and see how other people’s experience with the company went.
  • 4. Answering Your Questions & Concerns: does the company patiently and thoroughly review all of your options and give you honest advice about your HVAC system?

If the company can fulfill all of these requirements, you’ll be on your way to finding the best HVAC company in Charleston.

If you’re new to the area, we hope you find it is as special as we here in the Lowcountry do, and should you need any assistance with your HVAC concerns, review the questions above and you’ll be well on your way to having a comfortable stay in Charleston for years to come.

What Kind of HVAC System Do I Have?

Tuesday, March 1st, 2022

It is estimated that by 2024, the number of HVAC units sold will surpass 151 million worldwide. As the global climate becomes more erratic, both residential and commercial properties are relying on HVAC systems for comfort.



But, do you know what kind of system you have?



Many people move into a property and make do with what is already there. The problem is that this is not always the best solution. Below, we help you answer the question “What kind of HVAC system do I have?” and find the best one for your needs. 



What Kind of HVAC System Do I Have?



There are several types of HVAC systems you may have in your home. Below we have listed the most common types and how to identify them. 



1. Heating and Cooling Split Systems


Split HVAC units are the most common type of residential HVAC system. They have two separate main parts. One heats the home, while the other cools it. 



These systems are low-cost and easy to modify once the ductwork is installed. If you have areas that only require some heating and cooling they can be very energy efficient. 



One way to identify them is through the units used. The first will usually be inside the home for heating and is most commonly a furnace. A second will be outside and is the main cooling system.



The downsides to this are that the ductwork can be expensive to install. You may find allergens and dust also get pushed through the home should it not get regularly maintained. 



2. Hybrid Split System


Hybrid systems are very similar to standard split systems though they have a key difference. This is the ability to switch between power sources, mainly gas and electric.



Gas provides more complete, all-round heat but electricity is quieter and more energy-efficient. When you have a hybrid system, you can switch to electricity in the summer months when less heat is needed. As a result, efficiency increases, and utility costs are lowered. 



Other than this, they function in a similar way to a split system. Ductwork is required to push air through, which can be costly for a first-time HVAC installation. Systems themselves will be more costly than gas and furnace options, but you will save in the long term. 



3. Ductless Mini Split Systems


Ductless mini-split systems use several individual units, all connected to an outdoor compressor. These mini-split systems allow you more individual control over how each room is heated and cooled. 



This brings with it increased energy efficiency, as you only heat the rooms you are using. Small properties where it is not possible to install ductwork can also benefit from split systems. 



One of the main downsides is that on the heating side, they are not the strongest of options. If you live in climates where it is temperate in winter, then it will be fine. When you start to reach freezing or below it won’t have enough power to heat. 



As you need individual units, the initial cost can also be higher than other systems. Parts may also be tough to source when you need maintenance. 



4. Packaged Heating and Air Conditioning


With packaged heat and air conditioning, both units are stored in one. The compressor, condenser, and evaporator are all housed in a single unit. In commercial buildings, they are usually on the roof, though for a residential HVAC system they will usually go in the attic space or top floor storage. 



These units are very efficient, though they are not always the most powerful heating solutions. As a result, they are not always the best HVAC unit for colder climates. More powerful gas and heat combination units would be more effective. 



5. Geothermal Heat Pump System


A geothermal heat pump system utilizes the earth’s natural heat and transfers it to your home. It is collected through a series of pipes installed under the ground. 



When the home needs to be heated, the refrigerant in the pipes collects the heat. Cooling the property uses the same system to take it from the home and release it. This method of renewable energy is becoming extremely popular for anyone who wants to reduce their carbon footprint. 



Heat pump systems are large, meaning installation is not easy. They are also expensive systems to purchase. You may also require ducts if you are using an air handler, increasing the initial costs. 



Luckily you will make this back over the system’s lifetime in energy. You may also be able to get state or federal rebates for the installation of some energy-efficient systems. 


Choosing the Best HVAC Unit for Your Home



When deciding on the best HVAC unit, there are a few considerations you should make. The first is that if you are trying to keep costs down, you should use the existing system type. This cuts down on adding ductwork and other infrastructure expenditure. 



Your next consideration should be the climate. If you have a property in the Lowcountry, then winters are short and temperate. This means you have a lot of choices when it comes to what type of unit to choose.



After this, make sure you have the right-sized unit. Should you get the wrong size, you may not have enough power to keep the home going. Alternatively, a unit that is too large will consume too much energy. 



Finding a Local Contractor


Now you can answer the question “What kind of HVAC system do I have?” You should be able to repair and replace it much easier. Don’t be afraid to contact a local contractor for help and advice. They will know the local climate and be able to advise on the right unit for your property.

What Does HVAC Stand For And Why Is It Important to Your Home?

Tuesday, January 4th, 2022

The HVAC industry touches the lives of millions of people each day.



From the moment we wake up to the moment we sleep, we all rely on HVAC in our houses and offices to live comfortable, healthy lives.



Though so many people rely on it, and you may have heard the term “HVAC” discussed before, let’s break down exactly what HVAC stands for.




What Does HVAC Stand For?



HVAC stands for Heating, Ventilation, and Air Conditioning. These three elements make up your home’s air circulation system. The term “HVAC” is generally used when speaking about the circulation system as a whole, rather than its individual parts.



 The acronym also refers to the various technologies that are used to control the humidity, temperature, and purity of the air in an enclosed space.



The HVAC system is one of the most complicated pieces of equipment in your home, but having some knowledge of it can help you recognize issues quickly, keep up with maintenance, and prevent expensive repairs. There are nine parts to your HVAC system that you should be familiar with as a homeowner:



  • Air return
  • Filter
  • Exhaust outlets
  • Coils
  • Ducts
  • Electrical elements
  • Compressor
  • Blower
  • Outdoor unit



Each element of the HVAC system works with the others to control the interior air quality. The HVAC system is an essential part of your home, as it is responsible for keeping the air you breathe clean and safe, not to mention regulating the temperature to ensure you stay comfortable. 




What Does Your HVAC System Do?



HVAC systems singlehandedly regulate the temperature, humidity, and purity of the air in your home. They also work to distribute the air among the rooms in your home, maintaining pressure and promoting good airflow. As mentioned, the three major functions of an HVAC system are:



  • Heating
  • Ventilation
  • Air Conditioning



These elements are interrelated and work together to provide you with the greatest indoor comfort. This collaboration makes the HVAC system the most effective means of regulating the air indoors. With an HVAC system, the air in your entire home will stay clean and cool 24/7.






The heating element of an HVAC system is essential to the functionality of your home. The heat in your home can come from a variety of sources, including:



  • Central heating
  • Boiler
  • Furnace
  • Heat pump



One of the main purposes of the heating unit is to generate heat for your home, a function that is absolutely essential during the colder months of the year. 



The heating element is also responsible for distributing the generated heat throughout your home. In the case of water, pipes are used to transport it to the faucets in your home once it’s been heated by your unit. 



Heated air is distributed via ductwork to keep every room in the house warm and toasty.







The ventilation aspect of your HVAC system is responsible for redistributing and purifying indoor air. It also replenishes oxygen by bringing outside air in to prevent stagnation and stuffiness. 



The combination of these functions makes your ventilation system the best way to improve your home’s air quality.



HVAC systems use a mechanical method of ventilation to control the quality of the air in your home. Controlled via an air handling unit, this method allows the system to expel odors and contaminants and replenish your home with outside air. Your ventilation unit is also responsible for controlling indoor humidity levels—an absolute necessity during hot Southern summers.




Air Conditioning



The air conditioning feature of the HVAC system is in charge of keeping the air in your home cool and comfortable. Fresh air is drawn into the system via an external vent and then mixed with indoor air before it is cooled down. An air conditioning unit also works to reduce the humidity of indoor air to reduce moisture and prevent your home from feeling stuffy.



Just as the heating element is essential during the colder months, a quality air conditioning system is necessary for comfort in the summer when temperatures rise. Combined with the heating and ventilation elements, your HVAC system ensures the air in your home remains clean and comfortable.




HVAC System Maintenance



To keep the air in your home comfortable and free from impurities, it’s important to provide your HVAC system with regular maintenance. Most of the maintenance you’ll perform as a homeowner is strictly preventative, and is meant to ensure your HVAC system operates at its full potential. Some common HVAC problems that homeowners frequently experience include:



  • Leaks
  • Corrosion
  • Dirt and debris



To avoid these issues and more, make sure the area surrounding your HVAC system is clean and free from any clutter—two feet of space around all system components is ideal. You’ll also want to replace the filters in your system every few months to keep the air clean and pure. 



The best way to conduct HVAC maintenance is to create a plan that you can follow each year. Having a schedule ensures you’ll remember to keep up with system maintenance and will ultimately extend the life of your HVAC system.

10 Lowcountry HVAC Tips for Christmas 2021

Tuesday, December 14th, 2021

It is estimated that by 2024, the number of HVAC units sold will surpass 151 million. While many pay attention to the upkeep of their air conditioning in the summer months, winterizing your system is just as vital. But do you know how to prepare for the Lowcountry winter?


We can break down the tasks for you into handy points. Read on as we give our essential Lowcountry HVAC tips you need this winter. 


1. Clean the Outside Unit


Fall brings more debris than any other season. Leaves, twigs, and dirt are all in the air and they can easily find their way to your HVAC system. While you may not be using the air conditioning much during the winter, it helps to have it ready for purposes of purifying the air in your house. 


Turn off the power to the unit and remove the top cover. Use a shop vac on a light setting and pull out any debris that may have gotten inside. A hose can also clean the fins, but don’t use a pressure washer as they can easily cause damage. 


2. Cover the Unit


When you winterize an HVAC system it is important to cover the unit. The winter brings a lot of adverse weather conditions. Though the unit may seem sturdy there are lots of internal parts that can easily get damaged. 


Covers can be bought at most home improvement stores, or you can simply use a well-tied down tarpaulin. Adding something heavy on top can stop it from blowing away. If this unit also serves your heating, then you will need to ensure you have a cover that does not restrict the airflow. 


3. Switch to a Smart Thermostat


Just one winter with a SMART thermostat will have a marked increase in your heating and cooling bills. These thermostats can not only be set on a timer, but they can monitor temperature and be operated from your mobile device. This increase in control results in less energy usage and lower bills. 


4. Clean Indoor Vents


The vents in your home help air circulate around the property. When they become clogged with dirt and dust the airflow is impeded. Numerous problems occur because of this. 


Firstly, your system has to work overtime as it needs to push more air through. Air that does come in is also contaminated with the detritus from the vents. 


An increased build-up of dust around the home may also signify you need the vents cleaning. All you need to do is give them a wipe down with a damp cloth to solve the problem.


5. Don’t Obstruct or Close Off Vents


Vents allow your HVAC system to breathe. Many people assume that by closing them off, they stop a room from being heated or cooled and save energy and money. This is not the case. 


Closing these off simply blocks the airflow and makes the blower motor work overtime. Build-ups of cold can also occur at vents that are blocked which results in condensation. Open your vents and make sure they are not obstructed. 


6. Clean Drain Lines


HVAC systems do not just heat and cool, but they also moderate humidity by taking moisture from the air. This moisture gets taken outside via the drain lines. If the moisture stays in them and does not move, then algae and mold can begin to form. 


Alternatively, schedule regular HVAC maintenance so that the drain lines are inspected and cleaned when needed. 


7. Replace the Filters


When air comes into the system through the vents, it can contain dust, pollen, and a number of other undesirable elements. The filters are there to clear this out, allowing clean air to pass through but trapping bad particles in them. After a while, these become clogged. 


When clogged, the air that does get through is dirty. Your system also has to work overtime to push more air through. You can prevent this by replacing your air filters. 


Luckily, it is one of the easiest jobs to do. Replacement filters are also cheap. They should be changed monthly though if you live in areas with high levels of dust you may need to do this more often. 


8. Listen to Your System


You can identify when your system has a problem by listening to how it sounds. Try turning it on and off. If there are any noises that do not usually occur, it may signify that something is wrong internally and you should schedule a meeting with an HVAC engineer. 


9. Turn Off Compressor Power


The air conditioner compressor is one of the most expensive pieces in the whole unit. If you are not using your air conditioning over the winter, then turning off the power prevents surges from damaging the unit. You also prevent any unnecessary drawing of power which can increase your bills. 


To do this, go to the breaker box and turn off the power before winter arrives. Make sure you remember to turn it back on in spring, as you may damage the system if not. 


10. Insulate


Insulating the house means that you have much better temperature regulation in the property. You won’t let cold air in and as such, you need to use your heating system less. Speak with an expert on insulation, checking everything from the attic to doors and window frames. 


Lowcountry HVAC Tips


Now you know the Lowcountry HVAC tips, add them to your home maintenance plan. If you don’t have time or the knowledge then hire some assistance.

Here’s How To Prepare Your Lowcountry Home For The Upcoming Winter Season

Tuesday, October 12th, 2021

Charleston’s fall temperatures mean you can break out your favorite sweaters, enjoy the outdoors without humidity and finally rely less on your home’s air conditioning — at least for some days. 


With South Carolina’s temperate climate, you might find yourself bouncing between turning on the heat and turning on the AC. Make sure your HVAC is ready for this transitional time.


The Challenges of Charleston Fall Temperatures


In October, Charleston fall temperature highs range from around 80 to 70 degrees. In the evenings and early mornings, the average drops to the upper 50s and 60s. By November, it can be closer to 50 degrees. This presents a challenge to your HVAC system. It has to be ready to heat and cool your home.


Your HVAC has been working overtime all summer, so fall is a great time for some routine maintenance. Fortunately, there are a number of things you can do yourself, but you should rely on an HVAC maintenance technician for more intensive repairs and seasonal preparation.



Fall HVAC Maintenance You Can Do Yourself


Because of Charleston’s mild fall temperatures, you might not have your heat or air on too much, but that’s all the more reason to do thorough routine maintenance. Inactive HVAC systems are magnets for debris, dust and mold. If you haven’t had your system on for a while, finding  it in disrepair when you need it is an unpleasant surprise.


Clean Off Your Outdoor HVAC Unit

Give the outdoor unit, or condenser, a quick clean. You can spray it off with a hose or wipe it down with a wet cloth. Before beginning, be sure to turn the unit off.


Clear the Area of Debris

The transition from summer into fall means your outdoor unit might be surrounded by debris. Whether you have overgrowth from the summer or leaves and branches in mid to late fall, clean a four-foot area around your unit.


Vacuum Your Heating System’s Vents

After getting your AC unit clean, turn to your heating system. No matter your type of heater, the vents should be cleaned regularly to make it more energy-efficient and safe for fall. Mild fall temperatures mean moisture and even mold can invade your vents.


Especially for residents with allergies, dirty vents pose significant air quality issues. You can use the hose on a regular vacuum cleaner to clean them before you turn on the unit.


Inspect and Change Air Filters

The International Association of Certified Home Inspectors recommends changing furnace and HVAC air filters at least every three months when in use. In Charleston, this means you may only have to change your filter once or twice a year. However, you should change your filters once a month if:


  • You have pets
  • You have a fireplace
  • Someone in your home has allergies
  • There’s construction near your home
  • You smoke indoors
  • You have a large garden nearby


If your filter is damaged, damp or moldy, you should replace it immediately. Due to the Lowcountry’s climate and coastal location, your filter is more likely than the average American home to be damp or moldy as fall starts.



Fall HVAC Maintenance For Your Local HVAC Company


There are many areas in an HVAC system you can’t see or access easily. Those areas are best left to a professional. Like your vents and filters, drains, pipes and vents can fall victim to Charleston’s seasonal temperatures and humid climate.


Clear Drain Lines and Pipes

While Charleston doesn’t normally have below-freezing temperatures, you still don’t want standing water in your AC system. It likely won’t freeze and burst pipes, but it becomes stagnant and breeds bacteria.


Clean the Coil

In Charleston, salt from the ocean and sand from the beach can collect on your AC unit’s coil. If left there all autumn, the coil will be corroded come summer.


Check Ducts, Pulleys and Belts

Once again, Charleston’s coastal location is a hindrance to HVAC systems. A technician can check all the ducts and moving parts for tears, holes and corrosion that frequently plague local HVACs because of salt, sand and high humidity.


Calibrate Your Thermostat

If you have an automatic system, a technician can calibrate it. With the balmy fall weather going from warm to cold frequently, your system needs to be able to tell when it should turn on and off. If it can’t, your monthly utilities will be unnecessarily high.


Inspect and Clean the Whole Heating System

Ever notice how weird a house smells when the heating system kicks on for the first time of the year? That’s from the dust, sand and dirt that accumulates throughout every season. Since there’s no air moving through it, all that stuff sits there. It not only smells musty, it can also clog vents and filters.


For Charleston HVAC systems, there’s also likely mold from the high summer humidity. Since fall and winter temperatures don’t get cold enough to kill bacteria, it thrives in corners of HVAC systems. Let a professional clean it and notify you if you need to repair or replace heat pumps, detectors or burners.

What is Air Conditioning Tonnage?

Tuesday, September 7th, 2021

If you’ve ever found yourself in a conversation with your HVAC repairman, you might’ve heard the phrase “air conditioning tonnage” when discussing your unit.


We imagine you nodded along, smiled politely, and understood zero of what they were talking about, since tonnage is a strange term that might not mean what you would expect.


Tonnage Explained


An air conditioning’s tonnage refers to how much heat it can remove from a building in one hour. Air conditioning units are rated at different tonnage — a one-ton unit can remove 12,000 BTUs in an hour, while a two-ton unit can remove 24,000 and so on.

The terms ton and tonnage in this context have little to do with weight. They’re referring to the overall efficiency of the AC unit itself. Once you know what the term means, it’s incredible how simple it is. However, it’s not a term that you would be able to figure out ourselves without some expert advice.


How Much Tonnage Do You Need?


If you’re contemplating whether or not you need a new air conditioner, then there a few things you should ask yourself. Upgrading a central A/C unit or investing in multiple portable A/C systems can be a big purchase in and of themselves.


However, that might be nothing to the increased energy bills you might end up paying due to your investment. So, before you invest in an 8-ton mammoth of an industrial air conditioning unit, find out a few things.


  1. How Big Is Your Home?

While we understand you might be investing in an A/C unit for an office or business, let’s focus on obtaining/replacing an A/C unit for a residence for now. The first thing you’ll want to know is the square footage of your home. Determining the size of the home and the volume of air inside is crucial to understanding how much power you need to manage a maximum cooling effect. Sure, a massive unit could turn your living room into a tundra, but why would you ever need it to?


  1. How Well-Ventilated Is Your Home?

A good reason to replace an air conditioning unit might be due to dilapidated vent conditions, poor airflow in the home, or cracks that lead to drafts. You don’t want your air conditioner to be fighting against stale air, or hot air coming in from the outside, so checking your home’s airflow is a good way to tell if it’s your air conditioner that needs to be replaced, or the walls and window seals.


  1. What Kind of Insulation Do You Use?

Different kinds of insulation can affect the overall efficacy of your air conditioning unit, so checking to see whether you’re using outdated or worn-out insulation is an important step to seeing whether a replacement is in order.


  1. Is Your Air Conditioner Breaking Down?

It’s not uncommon for an air conditioning unit to occasionally stop working. Like every other kind of mechanical equipment, things fail and parts break. However, if your air conditioning unit breaks down with regularity and always seems to need the same things fixed, then either you have a scummy repairman or it’s time to invest in an entirely new unit. Depending on the make and model, an air conditioning unit might only have a lifespan of a few years, so if you hear a death rattle every few weeks or months, it might be time to put your current A/C unit out to pasture.


  1. Have Your Energy Bills Gone Up?

A major sign it’s time to replace your A/C unit is if your energy bills have seen a noticeable increase when compared to recent years. Any time an air conditioning unit nears its end, its efficiency goes way down. This is due to a number of factors, but it’s all somewhat obvious — parts are degrading and don’t work as well, causing the unit to have to work harder and use more energy to pump out the same amount of cool air you’re used to. When this happens, it could mean a costly repair job every couple of years or an entirely new unit.


  1. Is Your Air Quality the Same?

Lessened air quality doesn’t automatically mean your air conditioning unit needs to be replaced. You might just need to have it thoroughly cleaned. However, if you continually notice stuffiness when you’re in the home, then there might be something off. The same goes for headaches or odd smells that occur when the air conditioning unit is functioning — this could be a sign you need to make an upgrade.


Why is Air Conditioning Measured With Tons?


When air conditioning was invented by Willis Carrier in 1901, the world was a different place, and we were still using Imperial units of measurement in science. For some reason, air conditioning science never adopted the metric system, and we still use tons to measure the efficacy of an air conditioning unit. But how come?


The answer might surprise you, and also make you laugh a little. Before air conditioners, the wealthy would cool off their hot summer homes with massive blocks of ice. Yes, really. They’d store the ice underground during the winter, then bring it out to make summer treats like ice cream and popsicles, and also to beat the heat itself. A ton was used to describe the amount of heat it took to melt a block of ice. So when we look at the inverse — how much heat an air conditioning unit can remove from a building — we use the terms ton and tonnage.

Here’s How To Tell When You Might Need To Replace Your Thermostat

Tuesday, August 10th, 2021

Did you transition to a work-from-home setup because of the health crisis?

Keeping yourself as comfortable as possible is essential to your productivity. When it comes to comfort, a reliable thermostat is important. Like any other device, a thermostat will eventually fail and malfunction.

Thus, learning how to tell if your thermostat is going bad is crucial. Continue reading below for a guide to detecting a bad thermostat and when to call an HVAC company. If you’re already prepared to upgrade your thermostat, contact us today!

Your AC Doesn’t Work Properly

One of the first signs of a possible faulty thermostat is a malfunctioning air conditioner. A thermostat works by communicating with your HVAC. It sends signals to the latter and tells it to increase or decrease temperature.

Hence, a problematic thermostat can send wrong signals to your AC. In turn, it can cause your AC to randomly turn on and off. It happens when the thermostat’s wiring sustains damage.

The same goes if your AC won’t turn off. Frayed wiring can keep the thermostat from sending signals to the HVAC. It causes your heating or cooling unit to continue running even when it’s unnecessary.

Thermostat Is Unresponsive

Another sign of a faulty thermostat is when it becomes unresponsive. It happens when the thermostat doesn’t have power. The display doesn’t light up, and it doesn’t show anything.

Your heating and cooling units will become unresponsive. A common culprit is an old battery.

Consider replacing the battery and see whether the thermostat works again. If not, the solution is more serious than a simple battery change.

You Notice Faulty Readings

A malfunctioning thermostat can also give inaccurate readings. A thermostat with incorrect temperature registers may have a sensor problem. Invest in another way to check your indoor temperature, like a regular thermometer to determine the accuracy of the readings.

Use it to get your home’s temperature. Compare its readings with your thermostat’s readings. If the difference is way off, your thermostat is starting to fail.

Temperature Shifts Often Happen

A faulty thermostat may also result in temperature shifts. Temperature changes may happen too often and without warning. It means your thermostat is already struggling to maintain your desired settings.

When the temperature shifts occur too often, lower your thermostat settings. If it persists, it’s time to call your trusted HVAC expert.

Unexplained Spike in Electric Bills

Another important indicator of a faulty thermostat is your recent electrical bills. Higher energy bills with no apparent reason can be a sign of a malfunctioning thermostat.

When the thermostat doesn’t give accurate temperature readings, it prompts your HVAC to work double-time. It will do so even if it’s not the optimal indoor temperature for your home.

The Thermostat Is Too Old

An old thermostat is always a candidate for replacement. Generally, thermostats provide decent performance for up to a decade. Around that 10-year range, problems will start appearing.

Older thermostats don’t have the key features that the latest models offer. If you’re still using a non-programmable thermostat, we recommend you switch to a programmable variant soon.

These thermostats offer more flexibility in managing indoor temperature. Invest in a smart thermostat to maximize your HVAC system. It comes with key features to improve your home’s energy efficiency.

It sends timely alerts when there’s a sudden change in temperature in your home. The geofencing feature allows you to control your thermostat even if you’re driving back home.

You can connect it to your smartphone and control it from there. Additionally, a smart thermostat can track your energy consumption.

Troubleshooting Your Thermostat

Before calling an HVAC repair company, there are a few things you can do to troubleshoot your thermostat. For example, set your thermostat to five degrees higher or lower than normal and see if your AC turns on.

If it doesn’t, something’s wrong with your thermostat. Check if the thermostat is active. Sometimes, homeowners push the wrong buttons. Make sure to select the “heat” or “cool” (or equivalent) setting.

Check the battery of your thermostat. Test whether it has power. A simple battery change sometimes does the trick. When it doesn’t work, turn off the thermostat and check the wiring. Turn off the breaker and open the cover. Examine the wires for attachment problems.

Do the same with the screws. Ensure every screw is tight and secure. Turn the breaker back on and check whether the thermostat functions normally.

Turn off the breaker and turn it back on after a few seconds. If nothing changes, turn the breaker off and open the thermostat cover anew. Look for the red and green wires (AC) and the red and white wires (furnace).

Take note, the color of the wires may depend on the model. Check with your manual to make sure.

Remove the wires from their port and wrap them around using electric tape. Turn the breaker back on and check if your AC or heater turns on. If it does, your thermostat is the source of the problem.

Additionally, test the voltage of your fuses. A blown fuse can cause your thermostat to malfunction.

When to Call an HVAC Expert

Learning how to tell if your thermostat is going bad will help you draw the line between troubleshooting and seeking an HVAC expert. If the troubleshooting steps don’t work or you aren’t comfortable troubleshooting yourself, call an HVAC company as soon as possible.

Find an HVAC services provider offering repairs and replacing thermostats. These professionals have the right tools and knowledge to address your thermostat-related problems.

How to Tell If Your Thermostat is Going Bad Now

Now that you know how to tell if your thermostat is going bad, you can save more time and resources. You can prevent a spike in your energy consumption and restore the proper indoor temperature.

Air Conditioner Running And Your Lowcountry Home Is Still Humid? Here’s What To Do

Tuesday, May 18th, 2021

Is your humid house making you feel uncomfortable?

It’s an understandable response, especially if you know your home’s AC is running. You would think that having your air conditioning operating correctly, that should already solve this issue. However, humidity problems may go beyond your air conditioner’s basic operation.

To tackle the issue, review our humidity rundown below and learn more about why your home’s humidity level depends on several different factors.


Causes of a Humid House

The first step to fixing your humidity level is to identify some potential causes. Knowing them allows you to determine whether your AC system has the right features for indoor humidity. Never forget that an AC system’s function goes beyond cooling a home.

Here are some possible humid house causes:


1. Body Warmth

On certain occasions and depending on the size of your living spaces, if there are too many people in those areas your house may feel muggy. Too many warm bodies within a confined space can alter the immediate area’s temperature making it feel warmer than usual, so you may want to adjust your thermostat to accommodate the extra company.


2. Cooking and Bathing

When you’re cooking, your house could become more humid than usual. The evaporating water from your stove may be the culprit. It’s why most kitchens have ventilation fans above stoves and ovens.

Bathing is another normal activity that contributes to the humidity. When you run your bath or shower, it releases both steam and moisture into the air through the shower. Like your kitchen, it’s best to get standard ventilation fans on your bathrooms.


3. Outside Weather

When it’s humid outside, it’s a no-brainer that it will lead to warmer than usual humidity levels in your home. Ensuring the entry points for that humidity are sealed up properly (all windows and doors are closed properly), can help sure up your air conditioner’s ability to remove humidity effectively.


4. AC System is Too Old

If your house is too humid, it could be because your air conditioning system is reaching the end of its useful lifespan. The average lifespan of a traditional air conditioner in the Lowcountry is between 12 and 15 years. Like any appliance, the wear-and-tear causes your old AC to be less efficient when removing humidity.


This issue is more noticeable if you don’t maintain your AC system regularly. If your AC is old, it might prompt you to pick between repairing and replacing it. Think about whether the replacement will outweigh the costs of buying a new AC system.


How to Optimize Your AC To Help Remove More Humidity


1. Make Sure Your AC Is Sized Correctly

In air conditioning, size will always matter. If your AC unit is too small, it will fail to make your home cooler and free from humidity efficiently.

Otherwise, an oversized AC will turn on and off more frequently. It happens because its compressor is too powerful. The system won’t run long enough to dehumidify your home.

Avoid having improperly-sized AC systems for your home. Consult a reputable HVAC company with enough expertise to calculate and install a new system as necessary.


2. Add a Dehumidifier

Even the best AC systems sometimes can’t keep your house free from humidity, so adding a separate dehumidifier may help with the excess humidity. This is especially useful when your system has no advanced humidity controls.


3. Inspect Your Ductwork

Excessive air leaking from your ducts could cause a humid feeling inside your house. If you can’t find a viable source, inspect your ductwork to check for leaks. In most cases, your home’s moisture comes from outdoor air leaking into your interior via your home’s ductwork.


4. Keep Your Air Conditioner Coil Clean

The heat and humidity won’t go away if your indoor evaporator coil is dirty and dust-covered. It applies even when the coil is slightly dirty. It might not prevent the AC from cooling your home, but it can impact moisture removal.

One solution is to change or clean your air filter. Follow the manufacturer’s instructions, and you’ll be fine.

Your coil is less likely to get dirty when your air filter is clean or new. When the filter is dirty, the blower fan will cause particles to enter your air conditioner. As time passes, the debris will accumulate on the coil.


5. Adjust Fan Speeds

A lot of systems move air at a faster rate to help cool your home quickly. However, faster air movement may not be ideal if you’re getting rid of the humidity, so adjusting the fan speed down may allow your air conditioner to remove humidity more efficiently.
