I completed seasonal AC maintenance on a Rheem Prestige Series unit. The work included cleaning both evaporator and condenser coils using coil cleaner, which ensures efficient heat exchange. I checked refrigerant levels and added R-410A refrigerant as needed. I inspected and lubricated the blower motor and fan to ensure smooth operation. Additionally, I tested the capacitor and contactor for proper functionality. Finally, I replaced the air filter with a MERV 13 filter and verified the system's overall performance, ensuring it operates efficiently and reliably.
