Hvac maintenance in Bethlehem, Georgia. Three systems. Changed filters. Chemically washed condenser coils. Tested mechanical and electrical components. Found heavy amounts of mold in basement air handler, recommend pureairx air purifier to kill mold, bacteria, germs and viruses for improved air quality. Found basement blower capacitor to be weak (7.5mfd). Recommend repair. Found basement duct work under sized and one of the return ducts squished.
