Garnet Valley, PA

Performed tune up on Amana ac’s, checked indoor blower motor and checked and cleaned drains and tested temperature split. Changed both filters and checked outdoor units compressor and fan motors. Tested refrigerant levels and tested capacitors and checked all electrical and mechanical components. No issues with either unit at this time.

Performed precision a/c tune up on Bosch heat pump system. Replaced 16x20x4 air filter ( homeowner provided). Checked all electrical connections and components. Check temperature split. Cleaned out easy trap. Recommended installing wet switch in case of water leakage to shut down the system. Installed wet switch. Checked all the readings on Bosch heat pump system. Check refrigerant pressures and temperature at indoor and outdoor units. System system is working fine at time of service.

Completed (2) Heat tune ups First floor filter ok Aprilaire 413 Replaced second floor system filter 16x25x1 Completed humidifier service for basement system: New Aprilaire 35 water panel. Humidistat was set to maximum setting when I arrived. It will run constantly when there is a call for heat this way. Opened bypass damper, ensured drain was clear, water flow is set correctly. For BOTH furnaces: Inspected burners, heat exchanger, inducer assembly; burners for first floor system can be upgraded to stainless steel. Left estimate for this. I cleaned them today but they can become corroded enough that they need to be replaced. Second floor burners are stainless. In very good condition. Cleaned flame sensor, verified flame rectification circuit Ignitor in good condition verified ohm reading Confirmed proper gas pressures Inspected wiring and controls Measured temperature rise and static pressure Combustion and draft tests: Pass Both systems operating well at this time.

Wired transformer from EAC contacts to power humidifier contacts during heat pump operation. Tested afterwards. Went through humidistat operation with Cymon. Cymon had attic insulation and basement air sealing work done a year or two ago.

Completed 6 month inspection for hybrid Trane XV Heat pump (3 Tons) 60,000 BTU natural gas furnace. Replaced 16x25x1 filter Measured heat pump temperature rise Tested defrost cycle For furnace: Inspected burners and inducer assembly Cleaned flame sensor, verified flame rectification circuit Ignitor in good condition, confirmed proper ohm reading Checked manifold gas pressures Measured temperature rise and static pressure Inspected wiring, controls, electric motors Combustion and draft tests: Pass System operating well at this time.

Completed Heat tune up for 5 ton Bosch inverter/ 80,000 BTU natural gas furnace. 16x20x4 filter Measured temperature rise and static pressure (in both heat pump and gas heat modes) Indoor and outdoor coil in good condition; Inspected wiring and controls including fan speed settings, equipment has surge protection. Monitored R410A refrigerant pressures. 130/345 EZ trap is clear, condensate pump in good condition. Combustion and draft tests: Pass Opened bypass humidifier damper and verified operations of humidifier. Set humidistat to 35%. Aprilaire 10 humidifier pad in good condition System operating well at this time.

Checked filter, checked air temp rise, turned on and tested humidifier, checked refrigerant pressures, tested heat pump operation. Ran furnace and performed combustion test. Unit is in normal operation.

Estimate

Performed QA on Trane Gas Furnace/Heat Pump system. Reviewed programming on system. Setup the Heat Pump and Gas Furnace lockout set points. Also increased cooling CFM air flow to 400 CFM per ton. Tested the wet switch and ez trap safeties. Poured water through the ez trap and through the furnace drains. Completed checklist form in system. Called David before leaving to let him know about the QA since they were not home during the visit. No additional follow up needed.

Performed precision a/c tune up on 2001 weather king air handler matched with 2009 Goodman r-22 a/c. Replaced 16x20x1 air filter. Checked all electrical conections and components. Tested outdoor capacitor. Found evaporator coil in attic is leaking r-22 refrigerant. Checked temperature split. Temperature split is 18 at this time. Also checked refrigerant pressures and temperatures. Head pressure on compressor was 262 very high. System is worn out. Recommended replacement of a/c and air handler. A/c is cooling at this time but do not know longevity of system.
