Great Service




Review of Supreme Service Today

Colin was very knowledgeable, diagnosed the problem. Also is making Supreme Air management aware that new units installed during the winter should have courtesy coolant level check prior to the warm weather.

Technician was fabulous but...




Review of Supreme Service Today

Technician ran through several tests and diagnostics but our problem is not solved. Outside temperatures were in the low 80s today and our AC system could not cool the house or reduce the humidity in the afternoon hours. Thermostat was set for 72, temps got up to 77 inside the house. I need this brand new unit to cool my house asap. Thanks Bill and Sharon Harper Friday May 31st

I like the notices you send by text and email with the picture of who is coming. I also like that the service representative calls and lets you know how soon he will arrive. Yonas is very professional.

Very Professional, great service.




Review of Supreme Service Today

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 replaced the air filter. I pressurized the ground loop to 65psi. I confirmed proper flow rate and heat of extraction. I checked the electrical wiring and electrical systems, all are within specification. Temperature rise in high stage heating is 25-30 degrees. Unit operating normal. I used foaming evaporator coil cleaner with a hand held pump sprayer to completely soak the coil pushing debris out to the surface. I used battery powered pressure washer to rinse clean. Coil is literally like brand new and should not get dirty again. Filter is installed properly and there are no gaps for air to pull into the coil.

When I saw the service call I immediately called WF tech support because I knew that they would be closed by the time I reached the job site. I explained that the customer had these faults and I had been instructed by tech support to replace several thermistors and that should solve the problem, but unfortunately it didn’t and one day later the same faults continue. Dave from WF tech support said all diagnostics performed previously were part of their protocol and that given this problem that there is only one other part that is the problem, the EEV board. The sensors just replaced actually plug into this board. Dave gave me the part number and told me to have it ordered. We all agree that to go to the job site without the EEV board would not make sense, given the fact that WF tech support would be closed by the time I get there and that there is nothing I nor any technician could do to bypass this fault. I called the service manager, CSR and the customer, Mr. Imas and made sure

Customer had a WHSP already that had absorbed a surge so there was a credit applied that will zero out the remaining balance shown. The dispatcher was made aware of the credit given. I installed WHSP and then installed the customer provided Reme Halo device into the supply plenum. I wired in the supplied transformer and showed the customer how to remove the bulb from the device.
