Job Stories From Charlotte, NC
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!

We are in the process of purchasing the above referenced property. The inspection report states among other that the attic insulation is incorrectly installed (paper side up) and missing in some parts. We'd like to get this corrected and need a cost estimate.
