Performed single system cooling maintenance. I checked amps, capacitor, filter, electrical, drains, cleanliness, ducts, temperature differential, and refrigerant temperature. The system is performing well mechanically and inside of manufacture specifications. I spoke with the home owner about issues that were noticed during the maintenance. I observed that the blower motor has build up present on it. This results in added wear on 5e blower motor and can cause failure. The customer had a u/v stick inside of the unit and it was burnt out. The secondary drain is currently plugged and without a back up float switch. The system has 2 air leaks on the supply side causing the system to cool the attic. I brought these noticed issues to the customer’s attention and provided options to address them.
