Very Professional, great service.




Very well trained personnel and very clean. May be best o maintain in contact with the homeowner on arrival time. We had the 8-12 slot and personnel arrived after 1PM. Why is the humidifier not part of the service specially since it was installed by supreme air.

Upon arrival customer showed me unit that needs repaired and left shortly after, asked me to close doors when finished. Upon arrival I found condenser shut off. Turned power on and checked heat operation. Found ac running and aux heat running. Checked installation manual and found thermostat needs to be setup for conventional, not HeatPump. Corrected settings and corrected thermostat wiring, had to switch W1 and W2 for aux and defrost operation. Returned power to systems and checked operation. Found heat operating normal. Ran HeatPump heat and aux heat. Then ran ac. Found ac operating normally. Put thermostat back to heat and ran again. Found outdoor coil is frosting and outdoor temp is about 60degrees. Per last dispatch, there is a leak on discharge solenoid. Need to return to repair, customer has heat now.

Upon arrival I was told that furnace was vibrating badly. System was off so I turned on heat and checked operation. Heard slight rattle from manual damper but once I closed set screw tight, rattle went away. Continued to run system and could hear blower making a lot of noise and furnace vibrating. Removed panels and found blower mount is tight and not creating noise. Removed board so I could remove entire blower housing. Found blower wheel isn’t straight, slightly wobbling. Found shaft key set screw was on curved end of shaft and not on flat end. Put set screw in correct place but Wheel is still wobbling. Removed wheel and found motor shaft is slightly bent as well. Quoting customer to replace blower wheel and motor. Unit is 15 years old but heat exchanger not showing rust or any signs of cracking. Customer also has power humidifier which is getting supplied voltage but neither fan or solenoid are working.

The issues I found were nest thermostat related. They were set up as single stage heat pump. I configured both to reflect the actual system. I then confirmed thermostat input to zone board output and checked operation of the dampers. The Nest were also setup to limit the auxiliary heat from running. During these very cold past few nights it is needed. I set both to max comfort. I checked the refrigerant pressures, 100/345. Heat of extraction normal. The compressor was locked out on freeze protect from last night. I reset it and thoroughly tested the system afte4 making changes to the thermostats. The unit is operating normal.

Found system with no power to thermostat . Furnace has a blown fuse . Removed all my low voltage wires and jumped out system and it fired up so knew nothing was wrong with the system . Added thermostat wire then outdoor wire checking for shorts . I ran a new piece of low voltage due to the junctions we had in the system so it was one compete wire . Once I added my humidfier my fuse shorted . Found at humidfier stat we had a short behind the stat . Replaced wire (2’) section 18-2 wire and started and tested system . Supply air 108 degrees and return air 70 degrees .
