Spring Pm On 04/19/19 On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filter cleaned checked EWP and LWP water pressure and temp perfect checked compressor capacitor good unit tested unit operating normal at this time highly recommended Evaporator coils and duct work needs to be cleaned.
Have someone come out to test ductwork for leaks for final inspection.
Customer needs to have the ductwork tested with a pressure hood to ensure there is minimal air leakage. This test is required for a final in Anne Arundel County. I arrived thinking there was an issue with static pressure or any other normal operational concerns I could check out. The test required is very specific and Supreme Air can schedule someone to come out to perform this test. I made an estimate to do this and explained to the customer. I asked the customer for payment for the duct testing and for the trip fee for today. Customer asked that the office please call them to handle payment. I called the office manager and the service manager to let them know the circumstances and the office will reach out to the customer to follow up with scheduling the duct pressure test.
On arrival checked thermostat was calling for AC: measure temp coming in and temp going out, voltage, AMPS, electrical connections,replace filter provided by customer (16x20x1),contactor, voltage absorption system rated for 40mf,actual 41.6. System is operating normal at this time.
Fall pm on 02/13/19 On arrival set units to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filters and replaced checked heat exchangers checked coils is cleaned .no recommendation unit operating normal at this time.
On arrival set unit to call for heat,unit responded ok ,checked defrost ok,checked electric heat .114 leaving .unit operating normal
Found burnt contactor at outdoor unit . Replaced contactor and checked operations. Suction presssure 115 and head pressure 310. System is operating
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
Replaced condenser fan motor and checked operations . Supply air 88 degrees and return air 68 degrees . System is operating properly
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. Iâ€™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
