AC1 Maintenance- check indoor and outdoor units Indoor unit - checked blower motor, cleared condensation line, checked evaporator coil, checked filter and changed, checked delta-t, checked ductwork, checked attic insulation Outdoor unit - Checked pressures, checked capacitor, checked contactor, checked all electrical connections, checked disconnect, checked fan motor and compressor, cleaned outdoor coils. Recommended- replace contractor and capacitor. Contactor has burnt and pitted contacts and capacitor is below 6% specifications.
Performed one system heat pump maintenance. Indoor is a carrier 15kw ECM horizontal air handler. All three heat strip working. Blower motor is not over amping. Wiring in good condition. Coil is rusted and has smaller refrigerant leaks hiding behind rust. Leak detector did signal refrigerant leaks. Outdoor unit has an ok charge so it hasn’t leaked out much of its refrigerant. Compressor is operating, condenser fan is operating. Capacitor is getting weak. Homeowner would like to revisit repairs in spring time. No estimates requested today.
