5 Facts About Trane HVAC Systems You Need To Know

Wednesday, May 13th, 2020

With the increasing number of heating and air conditioning options available to Lowcountry homeowners, it can be a challenge to know what make or model will work best for their particular home setup.

 

With dozens of brands – each with dozens of makes and models — and more options than ever when it comes to HVAC setups (traditional central A/C, mini-split ductless systems, geothermal, etc.), sorting through all of the information can feel like a daunting task when homeowners plan on replacing their HVAC unit.

 

With anything you plan on depending on for years to come, you’ll probably start by looking at who is making the product and what they do differently that makes them the right choice.

 

To help you out, we started by looking at 5 important facts about Mitsubishi ductless systems and today we’re going to look specifically at Trane HVAC systems.

 

Trane is a brand name that may be the most recognized in the HVAC world and you probably have some familiarity with, but here are 5 important facts that you should know that sets them apart from other manufacturers in industry.

 

1. Trane Is America’s Most Trusted HVAC Brand 6 Years Running

For 6 consecutive years now — including 2020 — Trane has been recognized as America’s Most Trusted HVAC system by Lifestory Research. Lifestory Research is an independent market research firm that collects thousands of opinions over 12 months in order to generate a trust quotient and star rating system for industry brands.

 

Among 12 different HVAC brands, Trane came out on top again in 2020 — ahead of competitors such as Carrier, Ruud, Lennox and Rheem just to name a few.

 

2. Trane Designs, Builds & Tests Its Own Parts

Unlike many other manufacturers, Trane designs, builds and tests most of its own parts it uses in their systems. Other manufacturers often assemble their branded products using parts made from a collective “pool” of mass produced parts from generic factories around the world.

 

To ensure the level of quality and control over its performance standards, Trane’s engineers have compiled over 1500 heating and cooling patents that they use in the products they produce.

 

This fine tuning of exclusive technology helps ensure that you, the homeowner, are getting something above and beyond anything else out on the market.

Spine Fin Coils vs Traditional Copper Coils

3. Trane Utilizes Spine Fin All-Aluminum Coils

Among one of those 1500 patents Trane engineers have produced, probably one the most sought after by Lowcountry homeowners is its Spine Fin aluminum coils.

 

The reason homeowners want or request this type of coil is because of its stronger resistance to corrosion (important for our area), and its higher efficiency compared to other types of coil types.

 

The unique design also helps prevent clogging from sand, salt, leaves and other obstructions that can cause recurring issues with your HVAC system.

 

4. Trane Systems Have The Quietest Sound Rating In The Industry

On top of being the most trusted HVAC brand and employing unique engineering standards, Trane systems also have the quietest sound ratings in the industry. If you’ve ever lived in a home, condo or apartment with a loud HVAC system, you know how annoying it is to listen to it during startup and operation.

 

With our hot and humid summers we have here in the Lowcountry, you can expect your system to run quite a bit more so if you want a system that is felt, but not heard, Trane is a good bet for your Charleston home.

 

5. Trane Has Its Own Installation & Maintenance Training Program

Trane, like other manufacturers, has its own warranty program for the equipment they produce. However, to offer even better warranties and better installation practices it has its own “Trane Comfort Specialist” program. They only designate the title of Trane Comfort Specialist to qualified local dealers that pass a certain criteria and testing standards.

 

So when you’re looking at researching local HVAC companies to install your Trane system, be sure to ask if they’ve received the Trane Comfort Specialist designation. That way you know you’re getting the best pricing, warranty, installation and service for your next heating and air system.

 

(Bonus) Trane Offers Special Financing & Rebates Each Year

When it comes to saving money on your air conditioning installation, Trane runs special promos and deals each year, exclusively through its local HVAC dealers.

 

These deals include special financing (0% APR for 60 months) and instant rebates like the current Unstoppable Event happening now through May 15th.

 

During the event, you can get up to $500 in instant rebates on a qualifying Trane system — something that doesn’t happen often, especially during the busy summer season.

 

As you can tell from what we mentioned above, Trane systems are incredibly engineered, built, tested and give Lowcountry homeowners the level of performance they need year-round here in Charleston.

 

“It’s Hard To Stop A Trane” isn’t just their tagline, it’s what you will believe when you install one in your Lowcountry home.

4 HVAC Mistakes To Avoid This Spring For Your Home In Charleston

Friday, January 10th, 2020

Winter is still in full season here in the Lowcountry, but for today’s post we wanted to start looking ahead to the warmer, humid days of spring which, as we all know, can come up fast here in Charleston.

In one of our last posts, we mentioned why winter may be the best time to replace your air conditioner, so if you’re one of the several dozen homeowners that installed a new system this year, you should be all set for spring 2020.

If you haven’t quite pushed through a replacement project yet or don’t plan on it this winter then you’ll want to make sure you avoid the following common HVAC mistakes this spring; doing so can save you time & money when the temperatures start to climb again in the Lowcountry.

1. Not Scheduling A Maintenance Appointment

Even if you’ve occasionally had to flip on the A/C at some point before our warmer spring temperatures come in full force, we all know the kind of brutal operating conditions our air conditioners experience when those temperatures max out throughout the year.

Knowing this, it’s always important to have an experienced, local HVAC company near you do a thorough maintenance inspection to ensure your system works at its best during our peak warm temperature seasons.

Your HVAC contractor will inspect all components, both mechanical and electrical, and let you know if anything might need replacing. This is key for preventing major breakdowns, which you don’t want to happen when you need it most — spring & summer.

2. Not Signing Up For An Annual Maintenance Plan

While you’ve got your HVAC technician already in your home for the preventative maintenance, you should ask them about signing up for an annual maintenance plan.

With many HVAC companies, signing up for plan means you’ll not only get two annual maintenance inspections (one in the spring and one before winter), but also reduced pricing for replacement parts and labor, priority scheduling for service appointments (in case of a breakdown) and other perks when it comes to maintaining your system.

3. Delaying Air Conditioning Replacement Plans

There could be many reasons to delay getting an A/C replacement, but if you can, avoid doing so this spring.

When summertime hits, Lowcountry HVAC companies tend to be more booked up than normal, so you may end up waiting longer than you’d like to have your system replaced. Springtime is also a busy time of year, but odds are better you’ll be able to get a faster turnaround for a replacement project.

4. Not Searching For The Right Local HVAC Company

If you haven’t contacted an HVAC company for maintenance or replacement yet, be sure to do your due diligence to make sure you’re getting the right HVAC company for your Lowcountry home.

Whether you search online or offline, look for a consistent record of good online reviews and remember to ask your friends, neighbors and colleagues to see which company they’re using.

We hope you stay comfortable the rest of this winter, and if you avoid the above listed HVAC pitfalls we know you’ll have a pleasant spring this year as well.

The Top 3 Heating and Air Conditioning Trends For 2019 In Charleston

Thursday, January 3rd, 2019

First of all, we’d like to wish all of our customers, friends, family and followers a wonderful & exciting year ahead in 2019.

With that said and 2019 now fully upon us, let’s take a quick look at the year ahead and review some of the latest trends to look for in the world of HVAC and how you can stay ahead of the curve with your heating and air system.

1. Connected/Smart HVAC Systems Continue To Increase In Popularity

Most homeowners in the Lowcountry who have gone through with an HVAC upgrade the past few years or so most likely are familiar with some of the newer “smart” HVAC apps & devices on the market.

For those unfamiliar with “smart” or connected technology, it essentially gives you a way to interact remotely and collect usage & diagnostic data of your HVAC system. Using apps on your phone, tablet or PC, you can control your system anytime, from anywhere and using advanced data, allow you to granularly optimize run-times.

This freedom of control, operation optimization and diagnostic information allows you always know you’re getting the best performance from your system and if something should go awry, allow your local HVAC company to quickly resolve any issues.

This technology is not only available for residential air systems, but is also rapidly being adopted by commercial HVAC needs.

2. Variable Speed & Ductless Solutions

Every year in the HVAC industry, manufacturers continue to refine ways of increasing efficiency and creating solutions to non-standard applications.

Two kinds of HVAC systems that check both of those boxes and are rapidly being adopted by Lowcountry homeowners are variable speed air conditioners and ductless mini-split systems.

Most traditional HVAC systems operate in with one or more different operating speeds. They either run at 100% power and/or multiple stages at less than 100%. Multiple stage operation is intended to help with efficiency as your system doesn’t always need to operate at full power, so to speak.

While multi-stage systems can help efficiency, a newer operating mode on newer systems called “variable speed” can be significantly more efficient.

Variable speed operation allows your system to run more granularly, or more precisely, to meet the cooling & heating needs of your home. Instead of operating at a “high 100%” or “low 50%” mode, a variable speed HVAC system can adjust its operation to finite percentages. This means your system will consume energy more precisely, ultimately allowing you it to really optimize your energy consumption (and energy bill for that matter).

Along with the rise of variable speed adoption, ductless mini-split air conditioners are on the rise for many homeowners across the Lowcountry.

Ductless mini-splits allow homeowners to cool & heat areas of their home that either don’t have ductwork running to them, or if they want more unique temperature control over different areas of their homes.

In fact, even homeowners that have existing ductwork in their home are making the switch so they can cut out ductwork upkeep from their list of home maintenance tasks. This is especially true for homeowners that have recurring flooding issues (which can devastate an under-home ductwork system).

3. The Rise of Geothermal Heating & Cooling

In 2018 we’ve heard from more and more Lowcountry residents interested in geothermal heating & cooling options and we believe it will continue to rise in popularity in 2019.

State and federal tax incentives, along with longer operational lifetimes and significantly higher efficiencies, geothermal HVAC systems are being adopted now more than ever by forward-thinking Lowcountry homeowners.

Things can change quickly over the course of the year, but we believe the 3 HVAC trends above will help shape the Lowcountry’s HVAC needs for 2019 and beyond.

You’ll Be A Bit “Cooler” After Learning These 7 Facts About HVAC Systems

Friday, December 7th, 2018

Could you imagine life without your heating and air conditioning system?

You might be able to picture it for a little while, but if you start thinking about the extreme-weather months here in Charleston, it gets harder to imagine what life would be like without your HVAC system.

The equipment that keeps you cool & dry during the summer and warm & cozy in the winter is very often overlooked and sometimes taken for granted in today’s modern world. To help broaden your knowledgebase and understand HVAC’s impact on daily living, here’s 7 facts you might not know about HVAC systems.

Ice Block Air Conditioning

1. The Iceman Cometh

Simple air conditioning systems used in ancient times utilized ice blocks as the cooling source, with air manually fanned over them to cool different types of areas.

World's First Air Conditioning

2. The First Residential Air Conditioners Were HUGE

The first home to be fully air conditioned with modern technology (at the time) was in Minneapolis in 1914. It was 7 feet tall, 6 feet wide and 20 feet long! Unfortunately the owner of the home, Charles Gates never got to use it because he passed away before it was completed.

Whitehouse Air Conditioning

3. Keeping The President Cool Since 1929

Several attempts at cooling the Whitehouse with simple air conditioning systems were made with inconsistent results, but Herbert Hoover finally had a working central air system installed in 1929.

Architecture Pains With Air Conditioning

4. Pain In The Architect’s Neck

Before the widespread adoption of whole-home ductwork and central air conditioning, architects designed homes and other buildings with high ceilings, larger windows, broader breezeways and other ways to keep air moving throughout the home. When demand for AC and integrated ductwork increased, the whole industry of architecture had to change to account for modern cooling systems.

Window Air Conditioning Costs

5. Window AC Units Cost How Much?!

1932 introduced the world’s first window ledge air conditioning unit — albeit at a steep cost. In today’s dollars it would have been priced between $120,000 to $600,000.

First Ductless Air Conditioners

6. Ductless In The ’70’s

Asian manufacturers drive the push toward a fully ductless air conditioning in the 1970’s, mainly due to limited building space for ductwork and to free up windows.

Be A Lot Cooler With Air Conditioning

7. “Cool Man”

This one’s just for fun. While not directly related to HVAC, use of the word “cool” (as in “that’s cool!” or “he’s cool”) started in the late 1940’s when jazz musicians used it as a word of approval to describe their music; that jazz was “cool”. It was spread further to everyday use when teenagers started using it in the early ’50’s (to be “cool”).

A Quick, Simple Fall/Winter Maintenance Checklist For Your Heating And AC System In Charleston

Thursday, September 27th, 2018

With October knocking on the door, it’s time once again to get prepared for the fall and winter seasons here in Charleston.

We all know temperatures dip, but we sometimes don’t know how far or what kind of weather these seasons could bring. Last year’s snowfall caught many in the Lowcountry off-guard and stuck with heaters that weren’t working as well as they might have, leading to some chillier than normal homes here.

To help you stay ahead of the fall/winter curve (and hopefully warmer than last year), below are a list of HVAC related things you can do and check off your list this year.

1. Clear Debris From Around Outdoor Unit

With the recent hurricane and rains that brushed the Lowcountry earlier this month, be sure to look for any debris or buildup on and around your outdoor unit.

Doing this cleanup helps your system run more efficiently by clearing the airways that lead into the outdoor unit. If the airways are clean, the unit doesn’t have to “fight” to pull in air when it needs it, thus doesn’t have to work as hard during normal operation.

2. Clean Vents & Other Air Ducts

It’s natural for your vents and air ducts to collect dust and other debris over time. Cleaning these up not only helps air flow better out of them, but also helps your air quality as that debris won’t be blown around when your system is running.

3. Change Out Air Filters

It’s something that we’ve mentioned in several posts over the years, but changing out your air filters is a must — no matter which season it may be.

4. Listen For Noise or Unusual Sounds From Your HVAC System

Occasionally if there is something wrong with your heating and air system, you may be able to hear it. Turn down/off some of the devices in your home and listen carefully when your system starts up, runs and turns off. Report any unusual noises to your HVAC company when you schedule your maintenance appointment (wee #6 in this list below).

5. Test/Check Your Thermostat

We mentioned it in last year’s fall HVAC maintenance post but it’s still an important thing to do and worth repeating: test/check your thermostat’s settings and operation as you transition from cooling to heating your home.

If you have a programmable thermostat (which can save you up to 10% on your energy bill in many cases) make appropriate adjustments for fall/winter operation.

6. Schedule A Maintenance Appointment

Much like the car you drive, your home’s heating and air conditioning system should be inspected and checked out by your local HVAC company at least twice a year.

Having this kind of maintenance not only ensures that your system will be ready for winter (or summer), but also is a good way to prevent long-term problems. When your HVAC professional looks through your system, they’ll be able to find any small system issue (or potential issue) that if left unnoticed, can lead to your system to total breakdown.

These breakdowns generally occur when your system is needed the most (during the peak of winter or summer), but with regular maintenance you can help keep that from happening.

7. Consider Signing Up For A Maintenance Plan

With the importance of regular maintenance noted above, an easy way to ensure you don’t forget is by signing up for an HVAC maintenance plan.

Maintenance plans are available from most HVAC companies in the Lowcountry and include 2-3 inspections per year, priority scheduling, reduced cost part replacements and reminders to schedule your maintenance appointments.

8. Think About An Updated/Upgraded High Efficiency HVAC Unit

If your HVAC system is starting to get up there in years, some of the maintenance items may not totally ensure you’ll get the most out of your system this fall. HVAC systems have lifespans just like any other mechanical device so there will always come a time when you’ll have to replace.

The great news is that with summer winding down, many area companies run fall systems replacement promos and offers so this time of year is a great way of updating your home’s comfort systems.

Replacing Your HVAC In Charleston? Here’s What To Look For To Get The Best Option

Wednesday, December 20th, 2017

When it comes time for you to either replace or install a new HVAC system it can be a bit overwhelming to fully know & understand which heating and air conditioning system will work best for your home in Charleston.

Homes in Charleston come in all shapes and sizes, dating as far back as the 1700’s, to new homes only just completed here in 2017. With the range of different home architecture types and ages, an HVAC system must too, come in all shapes and sizes to accommodate the unique spaces here in the Lowcountry.

Despite the complexity of the home or system, however, there are certain characteristics (listed below) that can be applied to any situation that will allow you to know for sure that the HVAC system you’re choosing will be the best fit for you and your family’s comfort needs.

The Best HVAC System Will Save You Money With Its Efficiency

With homeowners reporting nearly 30-50% monthly energy savings with high-efficiency air conditioning installations, it’s clear that the best HVAC system for your Charleston home can – and will – save you money in the long run.

Knowing a system’s efficiency is as easy as knowing its Seasonal Energy Efficiency Ratio or SEER rating. Without getting into to too many technical details, essentially the SEER rating allows you to understand how much energy will be needed for the system to produce an expected output (cool air, for example) over a certain time period.

High efficiency systems have high SEER ratings (18 and above), meaning you get more output (your cool, conditioned air) while using less or the same amount energy. This also means your system won’t have to run as often to keep you comfortable, which leads to lower energy use and lower energy bills.

The Best HVAC System Is Sized Correctly

When we say “sized correctly” we mean that the output of a system correctly matches the size or makeup of your home. To understand the importance of proper sizing consider these two scenarios:

If your system is over-sized, it will do what is known as “short-cycling”. Remember air conditioners remove both heat and humidity from your home’s air. If your system is too large it will cool your home too quickly, leaving uncomfortable, humid air behind.

If your system is undersized, it will constantly run. This will drive up your energy bills and there’s a chance you’ll never be able to maintain a comfortable temperature throughout your home.

The Best HVAC System Type Will Fit Your Home’s Unique Design/Structural Needs

As mentioned above, HVAC system types come in all shapes and sizes. Whether you have a traditional central air conditioner system with a furnace, a heat pump system that can both cool and heat your home year-round or a ductless mini-split system — or some combination of these — the system type will fit perfectly with your home’s specific architecture and resource availability.

The Best HVAC Brand/Manufacturer Is Quality Engineered & Covered Under Warranty

With dozens of manufacturers and brands out there producing high quality products, like Trane & Mitsubishi, the best HVAC system for your home will carry a brand name that has a reputation for reliability, longevity and performance.

No matter which brand you’re thinking about going with, be sure to hire an HVAC contractor that is factory trained and certified by that company to install the system, which — in most cases — allows you to get a longer warranty for your system.

The Best HVAC System Is Supported By A Professional, Local HVAC Company

All things considered, you could get the right sized system with the best efficiency, system type and brand, however if you don’t get the right HVAC team to install it, you most likely won’t be happy with the results.

From system design & estimating to installation, maintenance and repair, hiring the right HVAC company in Charleston, is a sure-fire way to know that you’ll be getting the absolute best system for your Lowcountry home.

4 Quick Holiday HVAC Tips To Keep Your Family Comfortable This Holiday Season

Friday, December 18th, 2015

It’s been quite a year here at Carolina Climate Control and before we knew it the holiday season was upon us!

If the holiday season snuck up on you as is it did us, don’t worry — we have you covered. Here is a quick list of items to take note of to keep your guests comfortable during your holiday get-togethers.

1. Turn Your Thermostat Down A Few Degrees

During your holiday gatherings turn your thermostat down a few degrees. Most likely you’ll have your oven on and the extra body heat from your guests will naturally elevate the temperature in your home.

2. Check For Drafts

In each room of your home, check the caulking around the windows and doors to see if you’re leaking (or letting in) any cool air. If you notice any air leakage, seal them up with new caulking or weather stripping.

3. Check Your Blanket Supply

If you plan on having overnight guests, be sure to have clean, warm blankets in stock to make sure everyone has is comfortable during the night.

4. Have Your HVAC System Checked

While we always stress getting your HVAC system checked throughout the year, but this is especially important during the holiday season. Having your heating or air conditioning go out would definitely put a damper on your holiday festivities.

If you need a quick check of your HVAC system before your family comes to town, don’t hesitate to give us a call and we’ll make sure everyone stays comfortable in your home this holiday season.

3 Common Lowcountry Air Conditioning and Cooling Myths Explained

Wednesday, March 11th, 2015

Fact: You’ve Probably Of Heard At Least One Of These Myths.

If you’ve lived or grew up in Charleston or the Lowcountry you probably know of or have heard of a lot of air conditioning hacks and myths. Some of which seem logical and others that are completely off.

Here are three common air conditioning myths Carolina Climate Control has experienced over the years in the Lowcountry:

Myth #1: Setting A Lower Temperature On Your AC Will Cool Your House/Office/Building Faster.

Explanation. This is one myth that is hard for several home and business to get over. The fact is that your AC won’t work any faster to get your home or business to any particular temperature. So setting your thermostat at 55 degrees when you get home won’t cool your home any faster than if you set it at 65 degrees. In fact, doing this may cause your air conditioning to “ice” or freeze up.

Myth #2: Turning Off Your AC While You Are Away Saves Energy.

Explanation. This is a bit of a controversial topic as many arguments are made for both keeping your AC on and turning it off. Turning your system completely off definitely will save energy because it’s not being used, but you’ll have to get used to really, really warm temperatures starting it back up.

Instead of turning your AC completely off, simply adjust your thermostat 10-15 degrees higher than normal. This will allow your AC to turn on and deal with higher humidity levels during the day and allow it to cool your home down to normal levels much more quickly. Getting a programmable or wifi thermostat can help you manage this on a daily basis.

Myth #3: Closing Vents In Unused Rooms Will Boost Efficiency.

Explanation. Again, it seems logical that closing a vent will allow other areas to cool much more quickly. However, your air conditioning and duct system (if sized properly by a professional) is designed to cool your entire home or building so closing vents in unused rooms builds pressure up in your HVAC duct system. This can lead to a myriad of system issues.

If you need different air temperature in different places in your home or business, consider a HVAC zone system. Zone systems allow you to define specific areas of your home and control the temperatures with those zones. Call your HVAC contractor for more information.

There are many, many more air conditioning and HVAC myths out there, but these are the most common one we hear from Charleston and the Lowcountry. Did we miss any you’d like to know about? Let us know about it on Facebook.

5 Common HVAC Questions Answered

Tuesday, February 3rd, 2015

Your HVAC Questions, Answered.

Through our several years of HVAC service in the Lowcountry, we’ve encountered our fair share of air conditioning and furnace issues and installations. We’ve worked on historic homes, new homes, remodeled homes; offices, small and large businesses in Charleston.

With that experience we’ve put together 5 of the most common questions (and answers) about HVAC systems below.

1. How can I increase the efficiency and lifetime of my HVAC system?

While there are several ways to achieve efficiency and longevity of your HVAC system, one of the best ways to is to properly clean/replace your air filters frequently. Most HVAC companies offer this service as part of their HVAC maintenance plan so you won’t have to worry about it if you choose to sign up for one. Another simple thing you can do is have shades or curtains installed in rooms that are exposed to extreme sunlight.

2. How often should I clean or replace my air filters?

To get the best efficiency & filtration, replace or clean your filters at least once a month.

3. How much does a new HVAC replacement system cost?

Because every home, every business and every building is unique (especially in Charleston) it’s nearly impossible to put an exact price on a new system. The good news: you can get a free estimate from us, no obligation.

4. How often should I have my HVAC system serviced?

Regardless of what kind of system you have or how big your HVAC system is, to maintain optimum efficiency and to catch early warning signs of potential HVAC breakdowns your system should be inspected and serviced at least once a year. We recommend twice as some seasons may be harder on your system from year to year.

5. What size air conditioning and HVAC system do I need?

Perhaps the most frequently asked question we receive, it’s also the hardest to answer. Having an AC system that is too large may cool your home too quickly, leaving behind moisture that could lead to mold problems for your home or business. Also, too-large AC systems tend to short-cycle (starting and stopping quickly, repeatedly) which decreases the lifetime of your AC and increases your electricity bills.

At the other end of the spectrum, having a system that is too small won’t ever keep your home or business cool and will run constantly.

Because there is no “rule of thumb” for sizing an AC system only an experienced HVAC company can properly spec out your location and install the system that will yield the best (and most affordable) results.

Can Heating & AC Zone Systems Help You Save Money?

Tuesday, January 20th, 2015

Many homes and businesses in Charleston today heat and cool multiple areas (or zones) from a single Furnace/Air Handler. Consider a home that has a large second story space with a smaller third story area, or a business with 3 offices and 1 large retail space. Rather than installing individual systems for each location (which is expensive), a single properly configured furnace/air Handler unit can do the job, when combined with a zone system.

With a multi zone system, multiple sections of a business or home structure can maintain set temperatures through the use of coordinated thermostats and dampers. Zone systems can be deployed with Electric, Natural Gas/ Propane (LP), or Geothermal HVAC systems. Managing the flow of air requires more mechanical parts, including electric dampers, zone panel boards, bypass dampers, and a thermostat for each zone. Some systems can address up to 8 zones within one Furnace/Air Handler configuration.

Multi Zone System

Zone systems can Condition one specific part of a structure without wasting energy trying to condition the remainder of the structure. The sophistication of the installed zone management componentry (which can include: a zone panel, a variable speed blower, bypass duct(s) and more) determines a system’s ability to address a variety of fluctuating conditions. The goal is to maximize performance with a minimum number of systems. Why add another system when you could just upsize the equipment (to correct tonnage) and zone each space correctly?

A Zone System Does NOT Automatically Equal Low Utility Bills

As with any system required to manage many variables, zone systems must be designed and installed correctly before maximum efficiency can be achieved. Each zone in a home or business requires a set amount of airflow, expressed as CFM (or Cubic Feet per Minute) to condition the zone to desired temperature ranges. The components of each zone must be configured to deliver the proper number of CFM to achieve success.

It is not unusual (but it is unfortunate) for home and business owners to experience VERY high utility bills due to a variety of problems including: improperly sized ducts, non-calculated CFM, poor airflow, and single speed blower drives. For example, if a two-zone structure is installed utilizing a single speed blower drive the motor will only operate at one speed. In other words, it does not fluctuate airflow when one zone opens or closes. This causes inappropriate (excess and poor) airflow to the supply ducts.

To realize the full potential of a zone system, IT IS A MUST that a Variable Speed Motor be included in the blower drive configuration. These motors operate using static pressure levels. As one zone closes, the pressure in the ducts rises, and the blower slows down. This helps the zone(s) that is open to satisfy much quicker saving the consumer money on energy costs.

Failure to achieve maximum efficiency with a zoning system is rarely an equipment issue. It is typically related to poor design or installation of the HVAC ducts, blower motor(s), and caused by a lack of knowledge on behalf of the contractors installing these systems.

zone-blog-3

One of the best Zone Panels in the industry is made by Honeywell. It has the capability to operate with any system, thermostat, and damper type. Many home/ business owners do not know what type of equipment they are relying on to keep them comfortable. With a digital/ LED display of zones the Honeywell zone panel portrays which zones are operating and under what mode they are operating.

This panel also comes with a 5 year manufacturer warranty. Another issue with improperly sized ducts in a zoned system is the inability to remove humidity (moisture) from the home. This results in failed blower motors in many cases due to excessive moisture exposure, and these motors can cost several hundred dollars.

zone-blog-4It is imperative that each zone be tested for airflow performance throughout the structure if the consumer wants to keep energy costs to a minimum. In some cases a bypass duct will have to be installed to keep the static pressure in the ducts low when only small zones are operating. The best option when installing a bypass duct is to implement an external static pressure bypass damper.

This damper works off of static pressure (just like the variable speed blower) and modulates open/ closed according to the different pressures. This helps keep a system from short cycling and ultimately satisfying quicker.

As always, if you have any further questions about your HVAC system for your home or business in Charleston or the Lowcountry, feel free to give us a call: (843) 870-2076.
