Perform precision heat pump tuneup on 2021 Bosch heat pump system. Replaced 18 x 20 x 1“ air filter. Checked all electrical connections and components tested emergency heat. Homeowner showed me video of the noises. He was hearing from the heat pump from what I heard and from checking out outdoor heat pump everything seems to be in good working condition. Nothing out of the ordinary. Check temperature Rise. Check refrigerant pressures and temperature at indoor and outdoor units. Heat pump system is working fine at time of service. Also provided estimate for UV whole house air purifier.. emailed over information.

Fully assessed heat pump system. Found system only keeping 68° in the home. Heat pump system is a R 22 2009 Duane heat pump. Refrigerant pressures are 236/30. System is slightly low on charge. Compressor is also very noisy. Explain to customer that heat pumps will run constantly when it is this cold, especially r22 heat pump systems but because the system is slightly low on charge, it’s not maintaining temperature. Showed homeowner that the indoor evaporator coil was very rusted and corroded. Recommended to homeowner to replace heat pump system. Set up appointment with our office to give a replacement estimate..

Checked the air filter and replaced . Checked all wiring connections on the board. Inspected the oil filter the strainer and the nozzle and replaced. Check the electrodes and set for proper firing operation and inspected and cleaned the flue pipe and heat chamber. Tested the unit for smoke test and checked combustion and draft. Checked my supply and return temps oil side of the system is working fine.

Fully assessed thermostat, not connecting to app. Called train tech support. Rebooted router in home and also rebooted thermostat. Did a factory reset on the Z wave connection. When an app and re-added the device to the network this did finally work. Homeowner can now connect to the thermostat through her app. Explained to her any further issues to give us a call. System is working fine at time of service.

Performed precision heat tuneup on three heat pump systems and one gas furnace. Replaced two 413 air filters. Replaced one 313 air filter. Checked washable air filters on mini split system. Checked all electrical connections and components checked temperature rise. Performed combustion test on gas furnace, clean flame sensor. Checked refrigerant pressures and temperatures at indoor and outdoor units. Checked operation of booster fan. All systems are working fine at time of service. (1) 313 and (2) 413 Aprilaire

Performed tune up on trane heat pump, ran unit in heating mode, checked indoor unit and heat strips as well as indoor blower motor and electrical connections. Went to outdoor unit and tested all electrical and mechanical components, tested refrigerant levels, inverter, and compressor and outdoor fan motor. Checked level of outdoor unit and electrical connections as well. No issues with unit at this time.

Performed Tune up on gas furnace, checked unit I. Heating mode and tested combustion and gas pressures. Tested and cleaned flame sensor and igniter. Tested inducer and blower motor, changed filter and checked temperature split. No issues with unit at this time.

Replaced dual pressure switch and verified operations. Correct inducer draft and switch contacts are making. Completed heat tune up for 80,000 BTU natural gas furnace. Inspected burners, heat exchanger, inducer motor. Cleaned flame sensor, verified flame rectification circuit Ignitor in good condition, measured ohm value: Good Confirmed gas pressure Inspected wiring and controls. There is no surge protection. Left estimates for surge protectors for indoor and outdoor equipment Checked drains, added treatment tabs to pump. Measured temperature rise and static pressure Combustion and draft tests pass. There is water making its way back to inducer motor and therefore some rust in the cabinet. I left an estimate to add 3” PVC wye to the exhaust pipe to divert water to condensate pump. System operating well at this time. Homeowner paid for OEM pressure switch replacement today.

Upon arrival for maintenance on gas furnace I changed air filter. I cleaned the flame sensor. I inspected heat exchanger and burners. I checked blower motor and assembly. I checked the resistance of igniter. Checked all wiring and control board. I checked inducer operation and ensured hose port was clear. I checked gas pressures. Checked air temperature rise. Performed combustion test. Unit is in normal operation at this time.

Upon arrival for heat maintenance on heat pump tune up I changed the filter. Checked electrical and wiring and emergency heat kit. Checked blower motor and assembly. Checked delta t. Inspected coils. Checked fan motor and assembly. Checked refrigerant pressures. Forced unit into defrost. Unit is in normal operation at this time.
