Residential Air Conditioning

Air conditioning systems sometimes seem like they have a mind of their own — and often, they seem to “decide” to break down on the hottest day of the year. Don’t keep wiping away those sweat droplets. Contact our experts for AC repair, and we’ll be right there!

Residential Heating

As residents of Arizona ourselves, we know firsthand that life in The Grand Canyon State mostly revolves around staying cool. But even though we go many months without turning on the heat, it doesn’t mean our state never gets cold.

The best in town! The front office staff is communicative, fast, and easy to work with. Nick came out to do the diagnosis and later, the repairs. He was on time, very friendly, respectful, and efficient. Williamson’s heating and cooling fixed our furnace at a quarter of the cost that a competing company quoted us. I will definitely be using them again for any HVAC needs.

We recently had a new furnace and A/C installed. The installation took a crew of 3 and they did a superb job, it took a day, they cleaned up and we had heat on by late afternoon. After a couple of weeks Walter came out, checked the system, made an adjustment and everything is working fine. Walter worked on our A/C in the past and kept that 20 year old system running. Thanks to the whole Williamson team. Len

I have used Williamson's for several years and always have great service. This most recent maintenance showed some troubling findings with my heating system. Walter was wonderful to explain what the problems are and what needs to be done going forward. He was very thorough and was patient with me asking numerous questions after writing me several quotes for replacing my entire system. I really appreciate him!

Williamson's Heating & Cooling is the best Southern Arizona has to offer! Professional, honest and prompt. We LOVE our new mini split for our home office compared to the previous window unit we had. They really know what they're doing, highly recommend! #verynice

William son’s H&C has done wonderful work for me. I am on a service agreement, and they show me what’s going on with my AC in photos, and whatever they have completed. They make recommendations which I have found to be spot on. My most recent Tech was Nick Zimmerman. Young man was very personable, yet professional. I highly recommend Williamson’s Heating & Cooling.
