Tested temperature plot and burner as well as heat exchanger. No issues with unit at this time, still no grate on mechanical room customer was not home to speak with her about the issue.

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 amps on em heat kit and blower motor. Checked blower motor and assembly. Checked delta t. Inspected coils. Checked fan motor and assembly. Checked refrigerant pressures. Unit is low on r410a. Still has electric heat for heating. Will struggle to maintain temp in cold weather. Jenna said she doesn’t use the space and isn’t interested in doing anything with it at this time. Shut breaker off to outdoor unit and set tstat back to 55°. Jenna will contact us if she wants to do anything with it in future.

Blew out drain tubing. Serviced humidifier with number 35 humidifier pad and tested operation. Check gas pressure. Check temperature rise. Perform combustion test. Gas furnace is working fine at Time of service.

Perform precision heat pump tuneup on Gibson heat pump system. Replaced 16 x 25 x 1“ air filter. Checked all electrical connections and components. Tested lower capacitor and outdoor capacitor. Found one hole 40 amp, contactor, burnt, and pitted at outdoor unit. Also found compressor Vibrations to be a little rough when running , unit is also off level. Provided estimate to re-level heat pump and replace contactor. Heat pump is 15 years old and would recommend replacement check refrigerant pressures. Cycled system through defrost. Heat pump is working at time of service. Homeowner is going to talk to his wife then call in when he is ready.

Fully assessed bedroom not heating. Got homeowner to turn up the thermostat and heating mode when I arrived. Check temperature rise across air handler. Temperature rise was 24° very good. Put thermometer in vents in bedroom that is not heating correctly. Air coming out of vents was 93°. After going up in attic space found ductwork was just large flexes feeding small triangular duckboard boxes to each room. System does not heat correctly due to ductwork design. Asked homeowner if she wanted someone to come out to give an assessment on putting actual trunk ductwork with flexes to each rooms at this time she Does not want this. Asked her what she normally keeps the thermostat set at. She keeps it at 68° recommended to her that while having guests to raise the thermostat to try to help heat this bedroom, but it will only heat so well due to bad ductwork design . Someone previously went in the attic before I arrived and had got insulation on the floor.

Returned to site to install the universal pressure switch. Turned power off to system and removed the old Pressure Switch. Installed the universal pressure switch. Found loose connections on the wiring so I added new wiring connectors. Resorted power to the system and put into operation. Tested the system in heating mode and the REME turned on/off with the blower. Switched system to Fan only and lowered the blower speed down to 55%. REME was working and then shut off. Tested voltage on the plug and was reading 27 Volts. Removed the cover of the REME and could smell that it had burned up. Wiring was correct and voltage was reading correct. Something internally has failed with the REME. Spoke with the homeowner and let him know of what happened. At this point he does not want to deal with the REME since we have been there multiple times. He asked if we can remove the REME altogether and he gets a refund. Will speak with Joe and let him know of the situation.
