Service diagnostic found that the thermostat has failed and is not sending signal voltage on the O wire to the reversing valve. Loss of signal to the reversing valve is causing the heat pump to run in heat modes even when calling for cooling. I confirmed that the equipment was operational by also bypassing the thermostat and jumping the O wire. The system ran in cooling mode when I did. Options for repair were presented to the customer and he chose to have the thermostat replaced today. I replaced the thermostat and function checked the system. The system is now fully operational. System was set to the customer’s desired temperature and was running at the time of departure.

Performed heater check on a Carrier gas furnace. Checked electrical, mechanical, safety, and performance of the system. Drain line was cleared and treated. Return and supply ducts are clean. Blower wheel is also clean. Igniter is within value and operational. Flame sensor was cleaned. Inducer motor iss running at normal amperage. One of the wires running for a limit switch was resting against the inducer motor housing. This had put a small, discolored pit in the insulation of the wiring. The wire didn’t have any copper exposed, so I was able to tape up the spot and secure the wire away from any hot surfaces. No other major issues were found. See attached checklist for full tune-up details.

During my evaluation of the system I discovered the following: the AC blower and heating blower speeds were set to high. I took static measurements and dropped the AC speed one tap to help with dehumidification. The return side of the system is choked up and cannot be improved due to the construction of the home. I dropped the heating speed one tap in order to have a higher temperature difference across the equipment while still staying within design specifications. I also adjusted gas pressure to be closer to the target of 3.5” WC. No other major issues found. See attached checklist for full tune-up details.

Performed heater check on a Carrier heat pump. Drain line was cleared and treated. Return and supply ducts are clean. Evaporator coil, air handler and blower wheel are also clean. Auxiliary heat kit is operational, and all strips are working; strips drawing 18.7 amps. Condenser coil is clean. Condenser fan motor is in good condition. Condenser capacitor is within value. System was operating normally, and no major issues were found. See attached checklist for full tune-up details.

Performed heating maintenance on one furnace system. Checked all electrical, mechanical and performance of the system. Cleared and treated the drain line and replaced the return air filter with a customer supplied filter. No major issues were found, and the system is operational at this time. See attached checklist for full tune-up details.

Performed heater check on a Lennox gas furnace. Checked electrical, mechanical, safety, and performance of the system. Return and supply ducts are clean. Blower wheel is also clean. Drain line was cleared and treated. Flame sensor was cleaned. Inducer motor is running at normal amperage. No major issues were found, and the system was operational at the time of departure. See attached checklist for full tune-up details.

Replaced indoor TXV and liquid line filter dryer. Rebuilt and insulated primary drain line. Cleared and treated the drain line. Rebuilt secondary safety switch. Pressure tested refrigerant line set with nitrogen and pulled a vacuum on the line set. Weighed in charge to match manufacturers specifications. Everything is operational at this time.

Performed heating maintenance on one heat pump system. Checked all electrical, mechanical and performance of the system. Cleared and treated the drain line and washed the outdoor coil. No major issues were found, and the system is operational at this time. See attached checklist for full tune-up details.

Performed heating maintenance on one heat pump system. Checked all electrical, mechanical and performance of the system. Cleared and treated the drain line and washed the outdoor coil. I found that the system has a dirty blower wheel. I informed the customer and presented options to repair. He declined repairs at this time. No other major issues were found, and the system is operational at this time. See attached checklist for full tune-up details.

Service diagnostic found that the 120v to 24v transformer has failed. The system is being supplied with 120v of power up until the transformer. At the transformer the system had power, but no voltage was present at the 24v side of the transformer. Options for repair were presented to the customer and they chose to have the transformer replaced today. I replaced the transformer and function checked the system. The system was cycled on and off three times to verify operation. System was running at the time of departure.

Performed semiannual maintenance on one heat pump heating system. Inspected all Performance, Mechanical and Safety Systems. Did flush and treat the primary drain line and verified drain was clean and clear. Verified everything was operating within manufacture’s specifications for operation. Everything is working at this time. See attached checklist for full tune-up details.

Performed heater check on a Carrier gas furnace. Checked electrical, mechanical, safety, and performance of the system. Return and supply ducts are clean. Blower wheel is also clean. Igniter is within value and operational. Flame sensor was cleaned. Inducer motor is operational and running at normal amperage. Drain line was cleared and flow tested with water. Drain line was treated. No major issues were found and the system was running at the time of departure. See attached checklist for full tune-up details.
