Today we visited to evaluate the air quality. Ishwar noticed when the AC is running his allergies flare up. He suspects the ductwork should be replaced because it is original to the home. We confirmed the ductwork requires replacing. The ductwork is original metal with exterior insulation. The ducts are leaking at nearly every connection and the insulation is degrading. We also discovered the AC unit is designed to operate with a 0.3in. W.C. Static pressure but it is running at 180% of the rated load. This high pressure prevents the AC from performing as the manufacturer designed and this further contributes to poor air quality and creates the environment for mold growth inside the unit.
