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.

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.

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.

Posted in General HVAC Advice | Comments Off on Here’s How To Prepare Your Lowcountry Home For The Upcoming Winter Season

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
