Upon arrival I was told that neither HeatPump or aux heat were working. During diagnostics I found 30amp fuse blown on Common side of circuit. Replaced and tested, fuse blew right away. Shut off power to breakers and found all Compressor leads were grounded. Checked compressor terminals and found the same. Compressor needs to be replaced, R22 system. Then I went indoors and checked aux heat operation. Found heater pulling 40amps, in spec, but aux heater dropped out on high Limit shortly after. Opened up all panels and found evap coil almost completely restricted, dirty blower wheel, and a lot of spider webs in duct. Can also see droppings of dry wall and trash in bottom of return. Evap coil and blower need to be cleaned. Customer should have ducts cleaned as well. In all, Compressor needs to be replaced, evap coil and blower wheel needs to be cleaned, and ducts need to be cleaned. Suggesting system get replaced by severity of repairs. R22 system that needs a compressor will have to use

Variable speed outdoor fan motor had line voltage and a nominal amp draw but does not operate. I filled out a part order form. Part and repair covered under Trane 10 year extended warranty, verified by the office.

Customer filled me in on the recent service regarding a refrigerant leak and asked that I look for any sign that the problem remains unresolved. I’m happy today that the unit has normal temperature rise in second stage heating of +25 degrees. The flow rate is set higher than how we set up the flow rates at 3gpm per ton of capacity but the heat of extraction is normal for a flow rate of more than 4gpm per ton of capacity. The flow rate cannot be adjusted either as there is no valve on the piping. I pressurized the loop to 65psi. I checked the electrical wiring and electrical systems, all are within specification. Customer cleans the filter frequently and the coil and blower are clean. Blower speeds were set correctly for this unit. I did decrease the differential for auxiliary heat from 3 to 2 degrees. The unit should rarely go into auxiliary heat but with winter coming I explained to the customer why it sometimes needs to and if the differential is to high it can cause problems. No f
