I have three estimates for work to be completed while on site. I looked over all the bathroom fixtures to make sure we leave nothing unturned for best service.

Performed leak search on both circuits for RTU #3. Found circuit 1 is leaking at the condenser (heating) TXV power head, quoting customer to replace TXV. Pressurized Circuit 2 to 500psi, while looking for Leak, pressure dropped to 460psi but I was unable to find leak. No evidence of oil either. Need to isolate Evap and Condenser coils to verify where leak is. Could not do so today because of thunderstorm.

Replaced condenser fan motor 2 and fan blade, replaced C1 and C2 capacitors for RTU #2. Also found remaining (2) 10mfd run capacitors are barely out of spec, quoting to replace. Then found K10 outdoor fan relay stuck closed and outdoor fan 1 is constantly running, quoting customer to replace relay. Returned power to system and ran ac. Tested both stages.

Unit #1 all components working properly and system cooling properly, no concerns. Unit #2 same, cooling properly no concerns. Unit #3 superheat really high when checked but unit still cooling properly, system slightly low on charge, doesn’t seem to be effecting unit but recommend leak search to be sure. Unit #4 pressures seems normal but not cooling very well, system needs to be monitored. Unit #5 cooling properly, no concerns at this time.

Upon arrival I spoke to Kyle at BWW, he wasn’t sure how to get onto roof so I walked to mall management office. Office isn’t open on the weekend but security guard informed me that we will need to call mall management 4105405100 and give them our information so they can give us clearance to the roof. Then they will schedule an appt with us where they will have an escort show us the roof access. Could not perform service today.

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.

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
