Handyside Plumbing, HVAC & Electrical provided a heat pump maintenance cooling visit after the customer contacted us for routine maintenance to make sure their system was in good shape. During the visit, we found significant buildup in the system and cleaned it thoroughly. We checked refrigerant pressures and temperatures, checked the temperature rise, checked fan motor and compressor amp draws, rinsed both coils, flushed the drain pan and trap, inspected the blower wheel and ductwork, and changed the customer supplied filter.
