Upon arrival I went to roof with Nate. Found circuit 2 operating with 24 degree delta at Evap coil, unit only pulls in fresh air from outside, EAT 96 LAT 72. Circuit 2 running at 100psi suction and 350psi discharge. Refrigerant pressures and temps look ok, not performing leak search on this circuit because I have normal pressures and temps. Put gauges on circuit 1 to find it flat. Opened up all panels to find evap coil had been previously cut open and pipes still open. Coil is unrepairable and needs to be replaced. Sent picture to Nate and also uploading to file. Quoting customer to replace Evap coil. Can not determine if Compressor 1 runs until coil is replaced and refrigerant circuit closed. Found outdoor coil needs to be cleaned, causing higher head pressure. Also found condenser fan motor 2 was rattling loudly. Adjusted height of blade to stop rattle. Finally I found gas valve in off position. Inspected heat exchanger but found no cracks and barely any rust. Unclear if heat works a

Upon my arrival I went to the rooftop hatch with the manager on duty. At RTU#1 I found circuit #1 with the compressor not working because the wires have been pulled from the contactor because this circuit is completely flat of refrigerant. Circuit #2 is operating but is low on refrigerant as well. Both circuits need to be leak searched, the leaks fixed if possible, and then the remaining refrigerant recovered, both circuits pulled into <500 micron vacuum and charged with circuit #1: 328oz; circuit #2: 280oz of r407a refrigerant. This job will take most of, if not all day long. I completed a commercial work estimate and sent it to the office to finalize and reach out to the customer for approval ASAP.

Replace condenser fan motor, blade, and capacitor. Found unit had a blown fuse. Went out with the maintenance supervisor to pick up 4 fuses. Replaced the fuse. Turned the unit back on and the fuse blew again. Went through to every part on the circuit to find what was making the fuse blow. Found that the condenser fan motor was grounded. Ordered and picked up the materials for the job. Installed the new factory motor, blade and capacitor. Made all wiring connections. Started the unit. Found 1st stage compressor not wired up. Checked the compressor and the circuit has no refrigerate in it. Also found the wiring for the heat and the gas line has been shut off. Unit is R22 refrigerate and will no longer be available next year. Unit should be changed out to a R410A system. Only circuit 2 is running in A/C mode at this time.

Completed the P.M.. checked wiring and connections. Checked drain lines. Checked the air filter. Checked unit operation. During the p.m. found that the unit was losing the control voltage signal to the outside unit. Change the wire and tested the unit. Contactor know longer chatters. Found unit than going out on low pressure even with a full refrigerate charge. Jumped out the low pressure switch and got unit to run until it goes out on high head pressure. Customer needs a price for a new fan motor, blade and a low pressure switch. Would also like a price on a new outside unit.

The condensate drain line broke off from the air conditioning unit because it was brittle with age and in a vulnerable place. The drain line was also very clogged. I made a new drain line that was out of the way and hugged the back wall. There is still access to the drain cleanout and it drains into the same floor drain as before, but it is out of the way to prevent a repeat breakage in the future. Primed and glued the pvc and checked for proper drainage without leaks. The invoice is for 2 hours which is the minimum billing time for Commercial jobs and for parts. I had the manager on duty sign the ticket for acknowledgment that the job was completed and to their satisfaction.

Replace the heater kit and recharge heat pump and add internal leak sealer. I started off by finishing balancing the charge. I then added the leak sealer. In total 4lb 4oz of refrigerant were added. Running pressures in heat mode 84, 338. I then replaced the heater kit. One element on the old one was burnt out and one relay was not working. I tested the operation of the heat strips. All 3 energize and pull normal amperage. The unit is operating normal.

Only 1 of the 3 heat strips works. It’s a 15 KW heater kit. The unit is low on charge. Need to return with the heat kit and leak sealer. The thermostat is set to auxiliary heat at this time. I completed a parts order form. Customer signed up for service membership renewal. The price on the estimate does not include the 15% discount. Please fix this in the office. Customer paid $700 toward the repairs.

Upon arrival I met Alex and Yonas on site. We met with manager and informed her that when we arrived we found Pump was leaking badly and boiler wasn’t firing due to water flow switch not closing. Jumped out switch and boiler started running. Boiler should run no problems after motor is replaced. We shut off water flow and drained piping. Removed old motor and installed new one. Replaced motor from flange to flange. Cleaned flanges off before installing gaskets. Tightened bolts and opened water valves. No water leaks detected. Wired in pump and turned power back on. After water circulated for a minute the flow switch closed and boiler started running. Checked operation and found no additional problems. Unit operating normal.
