Carrier geothermal heat pump. Found system locked out on code 4 low water temp. Reset unit and checked operation check after temp in and out 50/33. Temps rise 16 difference. 65/81. Check refrigerant levels 275/85 based on data from manufacturer pressures should be 300/325 over 110/120 at 50 degree water in. Pressure were moving all over. Some times will get low as 55/200 could hear compressor grinding. After minutes of running compressor stopped making noise but pressures were still bouncing. Based on carrier serial number unit was produced back in 2011. Provided estimate to come back and perform advanced troubleshooting will need to call carrier for further help.

Looked over customers system and we came to the conclusion that due to the unseasonably cold and dry conditions outside that the steam humidifier is running much more frequently and consuming power for the humidifier and the blower motor so I showed him how to adjust his humidity settings and bumped it down by 5 percent and told him to see if his energy bill is less because of it.

Checked and tested system . Went through programming on thermostat. Wired in Generac . System looks good and running to standards. Tested steam humidifier as well .

Found failed 1/3 HP 1080 RPM blower motor. I have previous encouraged upgrading this system but for the sake of getting the dorm manager heat he decided to repair. I completed work today: Removed failed motor from air handler, housing then bracket. Shaft was very rusted. Cleaned blower wheel as best as possible. Was extremely dirty. Installed new blower motor using original hardware and wheel with new capacitor. Wired according to rescue motor chart. Left addition leads with wire nuts in case we very need to use those speeds. Afterwards tested system operations. Replaced 20x20x1 air filter. It was extremely dirty. Last replaced in July when I did tune up. Recommend replacing every 2-3 Months. System operating well at this time. Strongly recommend upgrading this system ASAP as there is an R22 refrigerant leak which will cause AC issue in the cooling season. Office to send invoice.

Installed new Bosch gas furnace. Installed Aprilaire 2410 filter box. New 14x25 return drop and new supply plenum. New 30x30 drain pan, wet switch, condensate pump, EZ Trap and vinyl. Adapted to existing 3” PVC. Added intake drain. Adapted to existing fuel line. New blower surge protector. Installed new Bosch heat pump. New 30x30 pad with snow legs. New disconnect with surge protector. Flushed line set. Reinstalled REME halo and steam humidifier. Cleaned and tested out operations. Check pressures in spring time. Customer says they already paid $8,001.00 to dillan

Estimate

Fully assessed 2013 Amana hybrid system with heat pump and back up gas furnace. Other company mentioned that the blower wheel had some wobble to it. Examined blower motor as it was running and found that the blower wheel did have some wobble to it and this repair would require replacement of variable speed blower motor And blower wheel. This repair and itself would be almost $2000. Looked over heat exchanger and found a decent amount of rusting corrosion inside the heat exchanger did not see any holes but definitely a lot of corrosion. Went outside to outdoor heat pump to check operation of heat pump system. Found compressor did start a little rough one time when I cycled system. After fully assessing system would recommend replacement. Set up appointment to give a replacement quote.

estimate

Return visit to replace hydronic parts. Thermal expansion valve spiral vent repair kit new pressure relief valve new boiler drain. and add purger on the return side of boiler. Also during same visit replace water heater expansion tank. Add pressure 65 psi in common water pressure 65 psi. Cycle boiler test operation ok pressure and temp ok. Both zones are heating.

No heat from carrier geothermal unit found blank thermostat upon arrival. Check operation of unit found 30 amp double pole breaker in the off position at the electrical panel. Was not tripped. Reset breaker and went to thermostat set thermostat to heat 5° higher the room temperature no operation from thermostat. Remove thermostat from base and reinstalled it unit came on, test operation check supply and return our temperature 19° split 85° out 65° in check water temperature in and out 56° coming in 32° water going out. Cut j3 jumper at board to match system style 10 degrees coil. System uses antifreeze. System stay running the whole time during a troubleshooting. Not sure why the breaker trip at this time potentially compressor starting to go bad. Perform mega test reading on compressor check capacitor OK.
