came out to a no cool. The customer explained to me that he change out the thermostat without killing the power to the air handler. I checked the air handler and the 3 amp fuse was popped. I continued to perform a full diagnostic check in the system and here are my findings. I found that the indoor unit was sound and in good shape. The indoor unit did not have UV protection nor did it have TE flood protection. I found that the system was draining properly. i checked the out door unit and the capacitor was out of range and need to be replaced. This causes stress on the compressor so i’d like to install a hard start kit on this unit as well. The outdoor unit also needs to be cleaned. Last i’d like to sign the customer up for a preventative maintenance Home Care plan.
