I am beyond impressed with Don and his team (Especially Molly) who came out a few days ago to install a new air-conditioning unit. Not only did they do an exceptional job but they explained exactly what they were doing and there were no hidden costs. Everything was explained upfront and the price I was given was ridiculously fair. Even low for what I was expecting. Don is clearly a man who takes professional pride in his work and is something of a perfectionist about detail and ensuring that every component part is working exactly as it should. He is also a man who cares about customer satisfaction. Because he wasn’t completely pleased with the airflow, he came out the following two days to refine the system so that it was exactly to his specifications, which I’m sure it’s not something every company would do. I will also add that he is kind, Trustworthy professional and fair. An Expert with 46 years of Experience. I would unconditionally refer anyone to him! Thank you, Don and Molly!

Don helped us solve our problem very efficiently and inexpensively! I have called him for a couple of problems over the years and he has always been very helpful. Keep his number handy for when you may need it.

Don and helper Molly were great! I couldn’t say enough about how they took care of everything with my ac during this awful heatwave. Working tirelessly to get it up and running, working even on the weekend. Thank you Don so much!

We contacted Don to get an estimate on installing a HVAC system in our house. He was quick to respond and gave us a bid right away. We were impressed immediately by his knowledge and experience to do our job. Don, with his assistant Molly, kept us informed and completed the job on time. They exceeded our expectations. It is obvious that he takes great pride in his work. We highly recommend Cassel Air Conditioning & Heating Service.

Cassell Heating & Air did an outstanding job replacing two rooftop units for us in Carmichael, CA. The pricing was very fair, communication was clear and consistent throughout the process, and the entire team was extremely helpful and genuinely nice to work with. Everything went smoothly from start to finish. Highly recommend them if you’re looking for a reliable HVAC company in the Sacramento area.

Don has worked on my 23 y.o. heating system several times over the last few years and every time I've called him he's come over the next day. Today he fixed a problem with my furnace, knew right away what to do and wouldn't charge me because he said it only took 15 minutes. He is so great to work with, knowledgeable and honest. I know when I need to upgrade my old HVAC he's the only one I will call. Thanks Don!!

Don installed our A/C a few years ago , recently I noticed two of our vents seemed to not be putting out the proper air flow . I called Don and he said” No problem I’ll be over tomorrow to take a look “ he was here the next day identified the problem and fixed it within 30 minutes and simply said “merry Christmas ‘ when I asked what I owed him . He’s a great guy ,kind,honest and hard working. hard to find these days I highly recommend him
