Air conditioning performance tune up two systems. Inspect blowers, evaporators and ductwork. Filters are clean at this time. Recommendation today is to change out the 1 in filter racks to 4 in which gives you better air quality and longer life on your blower motor. Refrigerant level is perfect on both units. Replaced one capacitor on the upstairs unit. Washed condenser coils. Systems are cooling properly at this time.
