Homecare inspection 2 systems. Called out for too much heat, customer was unaware there was another thermostat calling for heat and also sending heat upstairs due to failed dampers. System stops when not calling for heat. Checked electrical components, checked heat exchanger, checked blower wheels and cabins, flushed drains, tested condensate pump, checked ductwork, checked zone operation, replaced filters, tested thermostat operations. Found cracked heat exchanger, no flood protection, duct board plenums, broken drain line outside, and dirty ac coil for upstairs system. Found failing indoor capacitor, failed damper motors, duct board plenums, short on return air, dirty ac coil and no wet switch for main floor system. Gave quotes on repairs and correcting zoning on main floor, recommended getting quote for new system as furnaces are 20 years old and are in poor condition. Customer is a Homecare member as of today and the Homecare was also completed today for both systems.
