Larry H.
Replaced the thermostat for the upstairs with a Pro One thermostat, non- programmable. Checked the operation. System is operating properly
Larry H.
Checked system, all three zones were calling for heat. The second floor is cold, tried purging the 2nd floor, there was no water coming out. Purged the other 2 zones with no issues. The 2nd fl zone is frozen due to the piping is in an overhang on the house. The pipes need to thaw out. The outdoor temp will be going back into the 40’s starting tomorrow. After the pipe thaws out, recommend adding glycol to the system, to help avoid this happening. The 2nd fl piping froze last year,January 31,2022 and glycol was also recommended at that time.
Dyllan M.
Found the thermostat batteries were dead. Replaced the batteries(customer supplied) and the unit started working properly. Found the condensate pump was running non stop.

Through our diag we found that the air filter was plugged solid and it was restricting air flow. Replaced air filter and blew out the drain. We checked the charge and everything was working properly and the levels of Freon were right where they were supposed to be.

Through our diag we found that the condenser fan motor was seized. With talking to the customer we came to a conclusion that it wasn’t worth replacing the motor because of the age of the unit. We took pictures and measurements and model and serial numbers to replace the condenser and evaporator coil
Andrew H.
Upon arrival unit was off. Turned unit on and hooked up refrigerant gauges to the condenser and found that the system has no refrigerant in it. Unit was pulling into a vacuum due to a leak in the system. Took pictures and measurements for replacement quote.
Andrew H.
Upon arrival unit was off. Turned unit on and air handler and condenser fan turned on but no compressor. Upon investigation found that the wire to the herm side of the capacitor was shorted and disconnected. Also found the capacitor herm leg was weak due to the short. Customer did not want capacitor replaced due to home warranty only approving 150 dollars. Left damaged capacitor out and left wires safely disconnected. Unit will not run until capacitor is replaced.

Andrew H.
Upon arrival inspected condenser unit. Noticed buildup of pollen and dirt. Had t chemically wash condenser coil. After washing checked the pressures and found the unit was low on refrigerant. Had to add 2.56 lbs R410A to the system. After adding refrigerant pressures were 130/350 with liquid line 93 degrees. Took temps and had 62.8 supply and 76.3. Unit is working properly

Through our diagonal we found that the circulator for the house was always on when the burner was on disconnected circulator to stop trying to push water through zone heads. Heat was operational for domestic water. need a return to reconnect circulator at another time and figure out which zone head is shorted out because it is causing the contactor to pull in on the aqua stat. Next time we’re hear we need to figure out what zone head is bad and reconnect the circulator to the aqua stat. I already took all the tstat off the wall.
