For this call I performed recwork. A successfully changed out a faulty thermostat and a failed OEM condenser fan motor. The unit began to cool with the normal limits at the time of departure. Homeowner inquired about having an estimate given for a solar energy backup battery. I spoke with Rob Goldate about the inquiry and let homeowner know that we would reach out sometime next week to have Brian Hobson either go out and inspect the system or give a phone call to give an estimate. Homeowner was given a potential range of 12k-20k depending on the specs of her current solar panels. Thank you for choosing Comfort experts, have a great day!
