Performed heating maintenance tune up service on heat pump systems checking all electrical components and refrigerant balance, start up operation, shutdown, cleaning of indoor and outdoor units and treatment of drains.

Found system fully operational and electrical draws within manufacturer's specifications. Cycled unit in both heating and defrost modes to check for excessive noise. Did not discover any other issues at this time with the heat pump system. Could not access inside the apartment to check thermostat both doors locked but cycled system operation by forcing R G Y wires together at the air handler in the crawlspace.

Found power switch to boiler in the off position switch to on position boiler started up. Let it run for it to get real hot no issues. Replace the pressuretrol tank.

Infinity control fan mode was set to low. I reprogrammed it said it to auto. Verified through equipment status that it was off waiting for a heating call. Explain the thermostat and where to adjust these functions on the infinity control. If for some reason, the thermostat shifts out of auto by itself give us a call. We may have to replace the control.

Required replacement of expansion tank recommend filtrol 30 straight. Flushed boiler and added antifreeze to system. Checked system operation. Will quote replacement of expansion valve.

Found compressor making a lot of noise. Compressor is not circulating refrigerant. I believe there’s a bypass inside the compressor that’s stuck open. Check the capacitor amps and high voltage. No issues with that stuff. This systemizes are 22 so the system needs to be replaced. Inform tenant that thermostat should be moved to emergency heat, but use it sparingly because it’s very expensive to use.

Performed heating tune up service on all 3 systems checking all electrical components, refrigerant balance, cleaning of all furnace components, treatment of drains, performance of full combustion analysis, testing of unit start up, operation, shutdown. Customer complaint about mini split dehumidification during summer months causing high humidity when in dry mode. Tested minisplit in both heat and cool finding all electrical components and refrigerant balance within manufacturer's specifications. Referenced system manual to attempt to change dry mode settings. Will recommend a return in spring to check dry mode operation as it does not want to dehumidify without a cooling load on the building. Upstairs may require additional dehumidification but can be more accurately tested when outdoor temperatures and humidity are higher.

Performed heating tune up service on heat pump systems checking all electrical components, refrigerant balance, unit start up, operation, defrost, shutdown, cleaning of drains, Changing of customer provided filters. Everything looks and runs great! Upstairs filter is a 20x20x4

Found T6 thermostat minus button to lower temperature not working replaced with new T6 tested operation. This is under warranty.

Found capacitor to be broken not showing any micro ferrets. Compressor was drawing 2.5 A and refrigerant was not flowing. Replaced capacitor refrigerant was working fine. Compressor is now drying 4.5 which is normal for this unit. No other issues found today.

Unit is operating normally - refrigerant balance is perfect - all electrical components within manufacturers specifications - adjusted vanes on minisplit to give better air flow - removed grass from in front of outdoor unit that was impeding fan - reset remote on minisplit to 72 - recommend using ceiling fan in room to help move air around but have Mitsubishi fan reaching across the room on high speed. Recommend watching unit for a few days to track it's progress.

Found system capacitor had gone flat from 30+5 previously recorded - replaced capacitor and tested system for excessive electrical draws. Everything runs normally again.

Performed cooling tune up service on heat pump minisplit system checking all electrical components, refrigerant balance, unit start up, operation, shutdown, cleaning of filters, checking indoor and outdoor coils, treatment of drains. Everything looks and runs great!

Performed AC cooling tune up service on heat pump mini split system checking all electrical components, refrigerant balance, unit start up, operation, shutdown, cleaning of filters, checking of indoor and outdoor coils, treatment of drains. Everything looks and runs great!

Found unit compressor locked out on thermal lock out due to start capacitor failing and run capacitor starting to go out of range. Recommend replacing both at same time. System compressor needs to cool, will return tomorrow to complete repair and test system. Pulled unit outdoor disconnect to allow system to cool. Replaced run capacitor, start capacitor, and potential relay. Checked compressor operation by manually pushing contactor in. System will work now with a call for coolung.

Found system thermostat programming caused thermostat not to recognize outdoor unit. Reprogrammed thermostat and then cycled system to check operation. Everything came on normally and is working within manufacturer's specifications.
