Your tech Walter was very helpful and did everything he could to resolve the issues with the thermostat today, I would highly recommend him to anybody that needs help understanding this new technology, again thanks Walter

AC maintenance. Getting AC all checked out for hot Tucson summer. Excellent work! Brian was our highly professsional technician.

Great company, high quality, efficient and professional service and new installations, great and competitive pricing, fast response to needs .... Walter M. is the best technician and contract manager that I've ever worked with .... very glad that I used them for my new heat pump!

From their sale person Kelly to the installation tech Brandon 5 star to both..very pleasant young people..both knowledgeable and efficient

Jerry did a fabulous job. Smart and personable tech. Show and explained things.
A very professional individual.

Our hvac unit wasn't cooling. Jerry came out and withing minutes found the problem like a ninja. He's like a super hero but for HVAC! I wish Jerry can fix al my problems! Jerry is life! Jerry Jerry Jerry!

Jerry did a great job!!! I've been with the company for many years. I still miss Dave, but Jerry is a good replacement!!!!

Brian performed my A/C maintenance service in an outstanding manner on 4 May 2023. He was very professional and informative in answering any and all questions I had. 🙂🙂🙂

The "new" Williamson's Heating is certainly not the company we've come to know over the last 15 years or more. Had a furnace checkup on October 6th to complete our 2022 service agreement and the guy who showed up (1-1/2 hours late) spent, at best, 5 minutes on each of our 2 furnaces and didn't write up any details of the services (as per our agreement) he (couldn't possibly have) completed. I called their office to complain right after the guy left and then wrote to the company 2 days later via email and snail mail and have received no response. I have to assume residential customer service is no longer a priority in the new company.

The AC in my house was making an annoying rattle noise and my technician Tyler made it stop in a matter of minutes. Cool Willy’s is a great company!
