Mills River, NC Heating & Cooling

Found system acting like low on refrigerant - checked heat pump driers and valves - forced system into high stage, added 6 oz r410a and checked system operation- found thermostatic expansion valve (TXV) not adjusting to refrigerant balance changes. Tried adjusting system TXV - system TXV is stuck - recommend replacement of TXV

Found system low on r-22 refrigerant estimate about 4.5 lbs down. Recommend replacement of air conditioner and coil and potentially furnace as well due to age of equipment.

Performed AC maintenance tune up service on minisplit systems checking all electrical components, refrigerant balance, unit start up, operation, shutdown, cleaning of indoor and outdoor coils, treatment of drains.

Replaced transducer. Pressure tested. Pull vac and weigh back in for 10 a refrigerant. Tested transducer pressures from board to my gauges. They were pretty much the same.

Found that pressure transducer has failed on heat pump. My Gauge pressure is showing 93psi but board is showing 14psi with system in standby. called tech support to verify issue.

Found neutral wire for condenser fan motor fell out of its crimp and was hanging in space. Refit wire to contactor and cycled to check operation. Everything came on and cycled normally.

Found system about 3 oz low on r410a refrigerant and locked out with h5 error code - p2 low pressure lock out - removed fault and cycled to check operation. Everything appears to run normally again!

Found defrost board and sensor had failed - replaced and cycled system to check operation.

Found that the wire on the coil temperature sensor for defrost was shorting to the outdoor unit when system went into defrost. Put electrical tape on wire and tested system operation. System is now working properly.
