Amazing Professional Service!!




Review of Supreme Service Today

The customer service was very good, knowledgeable and professional right from the start. Best part was the technician. He took his time inspecting our systems, and provided a very honest assessment. Will gladly use Yonas again.

Great tech Bad business




Review of Supreme Service Today

Your tech Nicolas is wonderful. Your customer service from the office is terrible. We were told the tech was coming when he wasn’t Several times we go no call back. The worst part is that after paying over $400 for a part we are now told we need a new furnace and therefore wasted the $400 plus. I hear I may get some of that money back but I think the fair. Business practice would be to credit it all toward the new furnace. The tech is great but the experience with the company has been far from “Supreme”

New system problems




Review of Supreme Service Today

I had the system installed the end of October. The first really cold spell in January had the heat not turning on. It was an installation problem. They had reversed the drain lines and the heater stopped working. They got it running. No other problems the first winter. A/C won’t turn on in May when temperatures rise. A wiring problem. Supreme Air is great on coming out and correcting problems. It is too bad that their installers don’t do it right to begin with

Upon arrival I started with breakers. Replaced single breakers with tandem. Didn’t have correct ones so I had to run to Home Depot to get them. Added 2 pole breaker for aux heat circuit. Returned power to all breakers, tested aux heat, pulling 19amps on Circuit. Then I removed oil piping after shut off valves and installed caps. Then I replaced section of drain tubing with pvc, ran to sump and tested. Black pipe feeding into sump was clogged, this and the filter getting sucked into coil was the cause for water being in the pan. Vacuumed out all water and tested drain with 2 gallons of water, no leaks. Found drain pan safety switch wasn’t wired properly, now entire system will shut off if pan is full. Returned system to ac mode. Finally I installed NEST doorbell outside of garage door to house. In order for it to work properly I had to replace transformer at the breaker panel. Once powered up I completed the setup on the nest app and verified doorbell rings with chime and records wi

Upon my arrival I pumped the system down. I removed the txv valve and replaced it. I then vacuumed the system into a <500 micron vacuum. I opened service valves and added 1lb 14oz of refrigerant and adjusted the superheat setting on the valve. I took a photo of my gauges and corresponding superheat and subcooling, 6-8 & 8-10 respectably. I made sure the system was cooling with 20 degree delta temperatures across the evaporator coil. System is under a heavy load and as the living space temperatures decrease the supply temperature will decrease as well. Unit operating normal. Customer refused to sign second signature.

The filter was like new. I cleaned the condensate pan and drain lines and ran water to flush the debris out and to check for proper drainage without leaks. I pressurized the ground loop to 65psi. No faults recorded by the unit. I operated the unit in cooling mode, compressor speed #9. I confirmed proper flow rate and heat of rejection.

Upon arrival I found thermostat calling for ac and fan set to on. Went to furnace and found Control board reading IDLE. Removed blower panel to get to thermostat wire connections. Power reset from door switch so I waited for compressor delay. Ac started running but indoor fan didn’t come on but furnace control board is getting signal from both G and Y. Opened up Cool Cloud app and synced to furnace. Then configured furnace and setup cooling demand. App had to update so when it was finished I reset the system and unit came on and was operating normally. Tested unit multiple times and system is operating normal. Control Board wasn’t setup for AC airflow so when Y was given to furnace control board, blower went idle. Unit now operating normal. Also helped customer set up WiFi thermostat.
