MAD-AIR

Forced air heating ard air corditioning duct systems in residential housing have been largely overlcoked in house diagnostics. Even the building is itself a part of the overall ir distribution system. When a duct system fails, it can have some serious effects on the home. Proper air flow within the corditioned space is as important as the air flow within the duct line. Failure of a duct system or even the closing of the interior dcors can create pressure differentials both within ard across the building envelope when the heating and air conditioning fan is in operation. These failures may cause increased energy usage, poor indoor air quality and even promote multiple moisture problems
