Homeowner had us out today because her system is not cooling. Upon arrival we noticed that it is currently 73° inside the home and the system is off. Homeowner informed us that she’s noticed that the system goes from Cold to hot. We checked electrical and found that the 10 MFD capacitor for the blower motor is worn out and will need to be replaced. We also noticed some biological growth on inside of the system. We went out to the outdoor system which is from 2002. We noticed that the outdoor fan was not spinning. We checked electrical and found at the 45/5 capacitor was out of range and needed to be replaced. We also noticed that the contactor was very pitted and also recommend replacement. After replacing the 45/5 capacitor, we noticed that the refrigerant pressures were low and the system is an R 22 system. Presented all recommendations to homeowner. Homeowner chose to only replace 45/5 capacitor. We recommended getting an option for full system replacement.
