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.
