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.

I pressurized the ground loop to 65 psi. I set both flow rates correctly and checked heat of rejection. I cleaned the condensate drain pan# and drain lines and ran hot water to flush them out. I checked the electrical wiring and electrical systems, all are within specification. Both units are cooling with 20 degrees. Units are operating normal. I recommend adding an Intellistart Module to each unit to protect the compressor from shorted out windings by lowering the starting amperage by 50-60%. Intellistart is made by Water Furnace for Water Furnace. Customer wanted an estimate to talk over with there spouse. Customer has main panel box surge protectors, which is great. The upstairs units air handler had ultra violet lights installed but there are none on unit #1. I recommend adding a single Blue Tube UV light to this system and putting it in below the Trane E.A.C.

I pressurized the ground loop to 65 psi. I went to switch loop pumps over from “winter” pump to “spring” pump and the spring pump is broken. I tried purging air from it but it did not help, the pump is grinding and not pumping water. I left the winter pump in control and made an estimate to replace the left side pump and flush the ground loop. I made a part order form (estimate) for this. The filters had been replaced in December and were still in great shape. I checked the electrical wiring and electrical systems, all are within specification except the contactors are now showing pitting at the contact points and should be replaced. I made a quote for that as well. I cleaned the condensate drain pans and drain lines. Unit are operating normal and coolin* with 20+ degrees.

Upon arrival I went to condenser and verified solenoid was leaking at power head. This head can be removed so I used channel locks and was able to tighten head by a 1/4 turn, which stopped leak. Put gauges on system and ran heat. Found unit low in 410a because of previous leak. Added 2lbs of 410a to bring refrigerant up to spec. Ran defrost and let system satisfy. Unit operating normal at this time. Uploading video of solenoid showing that it is not leaking anymore.

Upon arrival I Leak checked HeatPump. Found refrigerant leak coming from pinhole leak on discharge piping between filter drier and reversing valve. Cut out piping and replaced with new because pipe went underneath coil and would be too hard to cut out hole. Used nitrogen while brazing and sealed leak with new section of pipe. Pressurized and found no additional leaks. Vacuumed system and added factory charge of 8lbs 2oz. Ran heat and found suction pressure dropping very slowly and discharge pressure not moving at all. Tested defrost mode and found compressor is not pumping refrigerant and pulling 1/8th normal amperage. Compressor needs to be replaced, quoting customer. Customer left site before I could inform him of compressor. Office please follow up with customer.

Upon arrival I was told that Trane HeatPump outdoor unit wasn’t running. Only aux heat heating up space. During diagnostics I was shown condenser so I removed panels to find a good amount of oil underneath coil and filter drier. Put gauges on system and found no refrigerant, system flat. Quoting customer to leak search and repair but speculate coil is where leak is located. Customer would like us to see if coil is under warranty before we come out just in case. Also, while talking to customer about problem, I was approached but a gentleman from Rockville Crane who is interested in working with us. Office please follow up, he did not have a business card but I gave him mine.

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.
