Goodman 5.0-Ton Outdoor Condenser w/ Indoor Air Handler

Service history records that blower wheel was documented to be separated apart in March 2022. Tech checked air handler A1 across from storage unit A148 and confirmed noise is coming from blower wheel. Fins have become separated from central hub. Blower wheel will need to be replaced. 15uf blower capacitor is also reading weak at 8uf. 3/4 hp blower motor appears to be running properly. Tech allowed it to run to check R22 pressures on AC unit 1 outside. Tech found head pressure high, suction pressure low, superheat high, and sub cooling high. There is no temperature drop across the filter drier. Tech suspects the wrong indoor piston for split system matchup is installed. Air handler has a size 093 piston bag with “piston change” written in sharpie. Outdoor unit is a 17 year old R22 heat pump condenser with a replaced compressor. Indoor unit is a 5 year old Goodman air handler with a 093 piston. To repair system, we will need to order OEM blower wheel, truck stock 15uf capacitor, OEM

Tech found breaker for Goodman outdoor unit D3 tripped. Found yellow wire on HERM terminal for dual run capacitor burned. Capacitor is in specs. Repaired connection and reset breaker. Breaker tripped immediately. Tested ohm reading on compressor at the terminals and found R22 compressor shorted to ground. Uploaded pictures of data tags and ohm reading. To repair existing 17 year old R22 Goodman split system, we would need to order and replace R22 compressor, add acid away, replace filter drier. System holds about 14 lbs of R22. Due to age, EPA phase out of R22, and likely cost of repairs, tech highly recommends system replacement. Need to have office follow up with customer about repair vs replace. System is down.
