They were very nice, they helped us order a furnace controller even we are outside of his service area. Then he came to make sure everything works properly. He was very efficient and charge reasonably for his time.

My AC went out on a hot day, but these guys David & Justin were fantastic! Same-day repair, friendly service, and they explained everything clearly. Highly recommend for all your heating, cooling, and air quality needs!

They were very good. We have the same technician come to our home. We are very happy with them.

Ken Slater did an excellent job in getting the old valve removed and replacing with a new one. Ken is a very hard worker, professional, knowledgeable and skillful plumber.

This person arrived to fix an issue I was experiencing with my air conditioner despite the short notice. He was not just friendly but clever as well. Strong recommendation!

Consistently excellent, professional, and punctual service. I have been a devoted client for 18 years.

Excellent business! Jim was very professional, & did an excellent job. He answered all my questions. & explained everything that he did.

Sean installed my HVAC system about 4 years ago and it went very smoothly. He returns periodically to monitor my system and completes routine maintenance to keep it in perfect running condition.

He is prompt, personable and very reliable. would not hesitate to recommend him to anyone!

The team provided me many alternatives for the repair and did a good job of explaining the procedure. They arrived on schedule and with professionalism.

Coworkers recommended me, and they performed well. Repairs are challenging in an older home, but they were cautious and cleaned up well. The cost was reasonable, and the completed job seemed to be sturdy.

Thermostat showed wrong time. Updated software and synced to network. Now everything stays accurate.

Heater not heating enough. Cleaned flame sensor, adjusted gas pressure, and now it heats efficiently.

AC kept tripping GFCI outlet. Moved to dedicated breaker and replaced contactor. Problem solved permanently.

Furnace rattled during startup. Found loose panel and screws. Tightened and added insulation strip to prevent movement.

AC unit outside kept freezing. Added refrigerant and reset defrost cycle. System now runs even in high humidity.

Cooling worked but airflow was stale. Cleaned indoor coil and sanitized blower housing. Air feels fresh again.

System wouldn’t blow warm air. Diagnosed open gas valve. Replaced it and heating returned immediately.

Thermostat display dimmed. Battery dying and wiring loose. Replaced battery and secured wiring. Now fully functional.

Cooling too slow after startup. Compressor was old and weak. Replaced it and added hard start kit. Faster cooling now.

Thermostat kept dropping connection. Updated firmware and changed Wi-Fi channel. System now stays online reliably.

A great shop that sells a lot of different air conditioners.
