Before and After Pictures from Charlotte

Air Conditioning Service in Charlotte, NC

Before After
Air Conditioning Service in Charlotte, NC Air Conditioning Service in Charlotte, NC

This homeowner had previously had a unit installed by GSM Services. Over time, it collected debris, like leaves and dust. The homeowner decided to call us for a FREE estimate on air conditioning service because they knew regular maintenance can help keep her system running smoothly and efficiently. We gladly visited the Charlotte, NC home to solve the issue. 

As soon as we recognized the debris around the unit, we knew that was the problem and had it removed. We also replaced parts of the unit that were not running as efficiently as they did when they were brand new. 

Now, this homeowner is experiencing better air conditioning throughout the home.

On this heating (PTU) precision tune up our Service Advisor, Thim performed maintenance and cleaned this furnace to ensure that the customer's comfort was at it's full potential.  

As you can see - cleaning and proper maintenance of your system is necessary.  Crawl spaces can be nasty, wet, dirty, moisture driven places that can hurt your heating and cooling system.  Having a scheduled tune up twice a year on a energy savings maintenance agreement (ESA) can prolong the life of your system.

Job Stories From Charlotte, NC
GSM TruComfort Signature Series Heating and Cooling System Replacement

We installed a higher efficiency GSM TruComfort Signature Series system for this home.  We also included a Nest Protect (Smoke and Carbon Monoxide Detector) which provides heads up alerts by voice and message to your smartphone. 

Attic Installation of New Heating System

Installations of new heating and air conditioning systems aren't always the easiest.  In fact, it is also hard to take good pictures as well.  Attic working conditions don't leave the best of senerios for working, our guys installed this one on a 86 degree day, which in an attic gets over 120 degrees (and thats a cool attic).  Attics involve tight working spaces, hot temperates, and also hard access. 

These photos are from a recent job showing the working situations that we do on a daily basis.  Imagine weaving duct work through this attic all while not falling through the ceiling.

 

Air Sealing, Insulation and Radiant Barrier - In your Attic

Check out this timelapse of an installation of radiant barrier and insulation performed in an attic to keep your home comfortable.  We first air sealed all cracks and holes that lead to your rooms of your home.  We want to make sure to keep the good air in and the bad air out.  Weather it is summer or winter - air sealing and insulating your attic can keep you comfortable and your power bills low!  Interested, Ask us how!
