Came out to perform preventative maintenance on Heat Pump for customer. The unit was installed in the fall of last year. Discussed with customer about filters and how system was doing. Changed filters for customer. I inspected the complete system. Checked the blower assembly, motor, evaporator coil, drain and overall condition of equipment in closet. Checked capacitor, amps, temperatures and pressures of Heat Pump in cooling and heating. Cycled emergency heat and checked operation of heating elements, amps, amd temperatures. System was performing well within manufacturing specs at this time. Discussed with customer about duct cleaning.
