Replace 40 gallon gas water heater with new pan ball valve and expansion tank
I found unit only heating by 18 degree temperature rise and refrigerant pressures were lower than printed data. I used leak detector and had refrigerant escaping from the uncapped true suction line. I tightened all valve cores and added 2lb 8oz of r410a refrigerant to obtain 105/325 pressures and temperature rise of 28 degrees. I found no leaks at any other braze joints or system components. Unit operating normal. I called Alex to verify warranty charge.
Found 3 hanging gas heaters not operating. First unit had cracked heat exchanger, should be replaced, shut off gas and power for now. Second unit had bad thermocouple, replaced and tested. Unit operating normal. Third heater wasnâ€™t piped in. Gas line is capped before gas valve. Informing office and preparing quotes for repair. Office please speak to them about either replacing first heater or moving third to first spot. Customer said they havenâ€™t used third heater since it doesnâ€™t have gas piped to it.
Upon arrival I found twinned unit for office area not running, thermostat blank. Went to ceiling and found front unit flashing twinning fault and back unit with no power. Found melted wire but for L1 on incoming power. Repaired wiring and restarted heat. Ran for some time and found no additional faults. Unit operating normal. Customer also asked me to look at hanging gas heaters in back area. Informed office and they told me to ask customer to call in and schedule another appointment.
I replaced the filter with one provided by the customer. I operated the unit on second stage and auxiliary heat stages. Blower speeds were set slightly higher than expected so I told the customer that I lowered the high and low speeds by one. I had 30 degree temperature rise after doing this, normal heat of extraction. I made a slight adjustment to the flow rate. The ground loop has more than adequate pressure. I checked the electrical wiring and electrical systems, including auxiliary heat strips, all are within specification. Unit operating normal. I took a photo of the ground loop pipes entering the basement from the inside, where they were sealed at time of installation. Customer said during heavy rains the sump pump would eject water from the basin but it would drain in around the pipes. I sent the photo to Alex as instructed. Customer would like more sealant applied from the inside and does not want the yard dug up to seal from the outside. I waited for a response but never hear
I took the top piece off and folded the piece of metal that was snagging the filters over on itself. I tested before sealing everything back to make sure the filter would slide in and out easily. I also had to widen the side guides. There were a few places around the return trunk that needed to be taped as well. Customer was there and verified that it is easy to access the filter.
Customer canceled call.
