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.

Donald helped out my senior parents when their heater stopped working. He arrived at their house within 20 minutes of my call, granted he is only 5 miles away but fast nonetheless. Diagnosed it quickly and instructed me how to repair it. Job well done.

Recommended by SMUD. This was the first company that answered their phone. The first contractor that showed up on time. Reasonably priced, knowledgeable, and hard working. I'm so thankful we chose this company. Donald Cassel was professional and reliable from first phone call. Couldn't recommend the company more highly!

During this extreme heat wave, our air conditioner decided to stop working (mind you with a two year old at home). I called 15 different places and they all said they were too busy and fully booked up and couldn't come day of. I found Don on Yelp and honestly it was the best choice! He answered his phone right away, and fit me into his busy schedule! Not only did he fix our air conditioning unit, but he also told me in detail everything that went wrong with our air conditioner, and gave me advice on how to maintain our ac unit. He was also very sweet to my daughter and dog. Thank you Don for

Don Cassel and team did a fantastic, thorough and detail job in replacing our A/C & HVAC system for a very fair price. They took care of permits and scheduling of inspection. Even the inspector said they are reputable and very thorough! Thanks Don!

Highly recommended!! Don is professional, reasonably priced and does solid work.

I first met Don Cassel about 3 years ago. My AC stopped blowing cold air--middle of summer, of course--so I called around to get someone to take a look. I knew my HVAC was very old (didn't know how old), so I was crossing my fingers I didn't need a full replacement. (The home was built in 1971, and I purchased in 2013.)

Don was readily available and squeezed me in as the last stop on his way home (we both live in Fair Oaks). Luckily, Don was able to get me back up and running with a new capacitor for, I

Don Cassel installed our system 29 years ago, and since we were pleased with his work then, we chose his company for one of our estimates this time. We were able to compare apples to apples by carefully taking notes with each bid.
Don was the only one who mentioned creating a larger intake vent for the system to improve efficiency and decrease noise. His bid was also substantially lower then the larger companies.
Pros: built a larger intake area
Completed in two days
Lower price
Cons: None

Dreading the need to replace the original HVAC system installed when the house was initially built 34 years ago, it ultimately came time to face the music. With an extended weather forecast calling for three days of triple digit temperatures midweek, coupled with the fact that the water heater has been leaking for almost a year, both were no doubt firm motivators to start looking for a reputable HVAC contractor.

Having patronized other "big name" plumbing and HVAC companies in the past, I was very disappointed with not only their lack of customer care, but also in their impulsive, predatory

I had three different companies come out give me estimates. Cassel air conditioning and heating was the very first ones to come out, I knew instantly they were the company I was going to go with. They did an amazing job they're very efficient friendly and always made sure to clean up after themselves they were here for 4 days and we're always very polite and very friendly even our old dog Lucy loved Don. They explained everything they were going to do along the way and did all of those things very professionally and efficiently. I would highly recommend Don Cassel and his company. I can't say enough

I spoke to Donald with Cassel Air Conditioning and Heating Service this weekend. He is very passionate about his company and the impression that he leaves. I recommend calling him up and talk to him in person so you can see what I am talking about.
Cassel Air Conditioning, THANK YOU for taking the time out of your Saturday to speak with me and answer all of my questions.

I had an old unit that eventually gave way and Don came out a few times before to take a look including one when some insulation for stuck in it. After having him quote out the cost for a replacement, he secured all the paperwork and installed a new unit and he and his team were great. He is honest and hard working and a true professional and his team is as well. I was recommended to him by a coworker and he raved about how great he was and he was every bit as genuine. My new unit looks great and runs wonderfully and it's thanks to Cassel Air Conditioning and Heating.

Heat went out right before the New Year, Mr. Cassel was able to get the part needed under warranty, and kept us from the cold before 2019.
Thank you for your prompt service, it was appreciated!

I called Cassel Air C & H because it was rated 5 stars on Home Advisor. The reviews were very helped and true. Don was great! He came over right away, accessed the problem, and quoted a very reasonable price. When he was done, I inspected it and it was such a clean and well done job. Don was professional and very nice. I could tell that Don was experienced in his field and knew exactly what was going on. I highly recommend Don.

Excellent service!! Our AC went out on us over night and after contacting several major big names who didn't seem to make us a priority, I stumbled across Cassel Air Conditioning and boy am I glad I did!

Donald the owner, was the one who took my call. I was very concerned that given I was calling on a Saturday morning and needed service same day, that I was going to get the answer every other company gave me of not until next week. Donald was so kind and told me not a problem that his son DJ would be out that afternoon to help.

DJ was very personable, professional and fixed our issue in

Don Cassel installed our A/C Heating system in 2006. Eleven years later the capacitor went out on a week of 108 degree days. Even though he was scheduled 5 AM to 9 PM all week, he made time to stop by within 24 hrs since he values customer loyalty. Thank you, Don!

I recently used the services of Don Cassel of Cassel Air Conditioning & Heating Services on the recommendation of my home inspector. I have two Goodman forced air heating systems
for the front and back of my home - both furnaces were blowing cold air and our house was as cold as a walk-in refrigerator. One phone call & Don was here within the hour. He diagnosed the cause(s) quickly, called his supplier to order the parts needed, drove to get the parts & was back within the hour to install them. Don is an experienced HVAC technician and took the time to clearly explain to me the
