For this cooling tune-up I inspected the customers air handler and condenser. The indoor unit was replaced in 2021 however the condenser is a 2008 Amana heat pump. The condenser is in need of major repairs like a new contactor, disconnect and Whip as well as all new thermostat wiring because the existing is weathered and the individual copper wires are exposed to the elements and will eventually cause a low voltage short. When I gauged up I had a 37⁰ SH with a piston, and a target of 18⁰, indicating the system is low on refrigerant. My overall recommendation is to replace the outdoor system with a more efficient and reliable one. Customer would like to have a Plumber come out for her water heater on Monday 14 April and have a CA come out on Wednesday 16 April.
