For this evaluation the customers system was not running because the thermostat has failed and was reading the internal house temperature was 11⁰F. The thermostat was set to 67⁰ however with how low the thermostat was registering the house temperature it was not sending a call for cooling. Two of the customers condensers were from 2008 and the other one from 2013 and one of the furnaces is from 2000. All the systems are r22 refrigerant and were not cooling efficiently. I told the customer the thermostat would need to be replaced because even after I reset it the temperature continued to drop and my psychrometer was reading that the house temperature was 80° but the thermostat was reading in the 60s and dropping. The customer would like to speak with a comfort advisor about replacing the systems to get a quote. Customer has an uninsuranble Sylvania electrical panel in the garage as well.
