Before and After Pictures from Charlotte

Before After

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.

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.

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.
