"I called Don on Sunday morning at 7 with no AC and temp forecasted to be on triple digit. The AC breaker tripped previous day when we hit 110 deg and after I reset, the AC was not working inside the house so I turned off the system. Most companies are closed on Sundays but Don picked up my phone while fixing his breakfast and showed up within an hour. Don checked everything and found no issues with my system. He explained what might have happened and changed batteries of my thermostat. Eventually the problem got resolved. Don spent about an hour in troubleshooting but refused to charge me anything since there was nothing wrong with my system. Don is a sincere and honest person, genuinely willing to help his customers. I highly recommend him and he is my go to person now for any future HVAC needs. "

"We called Don on a Sunday morning because our A/C unit stopped blowing cool air. He was able to come out within a couple of hours and promptly fixed our issue. He also took the time to describe the problem and helped with ideas on better cooling and heating options. We highly recommend calling Don whenever you need assistance with your cooling and heating needs. "

"Mr. Don is such a professional - came on time and checked thoroughly. He helped me tremendously. He is very HONEST and FAIR. Book no one else but his company. Thank you, Mr. Don. He did not tell me to do this. I just want to give a very fair review for a job very well done! Thank you."

"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."
