"Cassel Air has been my go-to for many residential HVAC repairs and troubleshooting in Sacramento County. They've done everything for us including installation/replacing entire systems through installing new thermostats and HVAC inspections. They are always quick to respond, on-time, clean, and efficient. I plan on using Cassel Air for all my future projects as well."

"Our heating went out and I had some over to look at it. They said they fixed it but it only worked for about a day. We had been without heat for two weeks at this point. I called Cassel Air conditioning and Heating Service and they fixed it the right way. Turns out we needed a new system. These guys were so awesome to work with. They installed my system without any problems. They were very nice and the best part is that they cleaned up after themselves. I didnt see one tiny smidgen of anything left on my driveway after they left. I HIGHLY recommend them. They were all great to work with."

"On Friday about 5pm i returned from the hospital after a 4 day stay. Found AC had gone out & house at 90 degrees. Called Don & he was out within 20 min & got AC Working. What a life saver. I was in no condition physically or mentally just out of hospital to deal with this. Don saved the day."

"Don replaced our downstairs HVAC, repaired the upstairs HVAC and installed a whole house fan.. His workmanship and attention to detail was absolutely amazing. I will recommend him to everyone I know! Our upstairs HVAC was replaced 9 years ago by one of those big name companies and Don's installation and quality of work is by far SUPERIOR..I even climbed into the attic to look and appreciate his craftsmanship and the quality of the installation. 5 STAR REVIEW!!"

"Best Heating and AC company I have ever had the pleasure of working with. You can tell Don has been in the business a long time and he knows what he is doing. He instills a level of comfort I have never enjoyed with other contractors I've worked with His professionalism and customer service is second to none. If you ever need heating or AC work done, Don is definitely the person I would recommend you call."
