Client Reviews

Part of the "comfort" of Williams Comfort Air is being comfortable with the company and its employees. Both my experiences with them have proven to me and my son that they adhere to the highest standards.”

- Becky

We can’t say enough great things about Williams Comfort Air! They were always friendly, informative, and on time. We have had several experiences, plumbing (Mr. Plumber) and heating, with them and all were very positive. They know what they are doing and are always willing to explain and offer options. If you want the best, call Williams Comfort Air.

- Sally O.

After two years, we are very well satisfied with our geothermal heating and cooling system. After hearing our friends and neighbors tell how much their heat bill is we are extremely satisfied with our Williams Comfort Air System. We estimate that we are saving about 40%...

Scheduling was easy even after hours. Received service next day. Tech named Michael was great and fixed three problems even one I sprang on him. Best thing is the leaks were fixed!

- Jeff M.

Great experience with Williams Comfort Air. My appt. was for 2-5pm on Saturday and they called around 11am advising they could be there in 30 minutes if I'd like. I jumped at the chance as this would free up my late afternoon. Michael Peacock arrived as scheduled. He was very knowledgeable and personable. He offered lots of insight and helpful tips to keep my heating/ac unit working most efficiently.

- Lisa D.

I called for my yearly heating inspection and was able to schedule quickly on a Saturday morning. When Chris Cook (technician) arrived he greeted me with a handshake and an introduction. He was professional, knowledgeable and VERY THOROUGH. He checked every aspect of the furnace found a small problem, fixed it and now my system is running better than ever. Great Tech- Great Company.
