Our clients’ satisfaction means everything to us.

Robert M.
Natomas, Sacramento, CA
After having another company come out and tell me that I needed a new air conditioner. I decided to get a second opinion. Dave from Christensen heating and air came out and and was honest with me and told me that even though my unit was getting old, it still had some life left in it. Glad I got a second opinion and apparently I called the right place. When it's time to get a new one, I will be calling them.

Michael went above and beyond helping us getting a new system installed. Always on time service is paramount. He is truthful and reliable. We have a new Carrier Unit and our home is wonderful! A truthful , reliable and impeccable worker! The inspector also committed on what clean job he did, showing his commitment to his work! You can't go wrong with this Company. Michael should be your only selection to trust your home to his care. Thank you Michael!
Lori Lee B.
Carmichael, CA
I'm so happy with this guy. We've been using him for about 3 years now. We have an older unit & he has helped us keep it running as long as possible. Mike is honest, very reasonable & prompt. I can't thank him enough for the great service. This is a small business you will want to support!!!!
Jason L.
Anaheim, CA
Our AC has water leaking and not cool, few vendors told us to replace it, costing more than $10,000 Mike not only provided us a rather simple solution and very low / insignificant cost, and was able to fix the problem very quickly, easily, very low cost and very effectively. Mike is the best, most honest person we ever come across, he is highly recommended by our good friend and we highly recommend him as well
Mike A.
El Dorado Hills, CA
We had one of our condensers fail in the middle of the night and Mike was able to come out first thing in the morning and quickly diagnosed and fixed the problem within an hour. He never tried to upsell us on service or repairs we didn't need, unlike too many of his competitors. He even gave us great advice on how to keep our system running longer and more efficiently. Very professional and trustworthy service. Highly recommended.
Barb R.

Amazingly responsive being able to support and understand the issue with my air con immediately. I appreciate their skilled, and very knowledgable service. I recommend Christensen for all your heating and air conditioning needs. Affordable value if you have diagnostic skills like they do.
Judy M.

Mike is a God send, so honest and courteous. He's helped me out a few times with my home a/c and is always reliable, affordable, and brilliant. It's such a pleasure to hire him, and I'm grateful he was recommended to me many years ago. Mike never fails!
Julie R.

These guys helped me out in a pinch. I had major problems with the previous company I used and just needed someone I could trust.
Mike G.
Sacramento, CA
Mike is an amazing person, very honest and kind. My Nest thermostat stopped working on the coldest night of the year and heat wouldn't work. Mike helped me diagnose and fix the issue on a weekend - taking time away from his own family so my family can stay warm. Will not call anybody else next time I have a heating or air conditioning issue. Thank you, Mike.
John D.

These guys do it right! Fast, Friendly, and didn't try to sell me a new system instead of repairing my old one...highly recommend! 🙂
Tom D.

Mike and his crew were amazing!!! They were knowledgeable, went above and beyond with every detail, and took the time to explain everything so we could understand. Best experience I've ever had with and HVAC provider. Customer service was second to none. I am so glad we called Christensen Heating and Air. Thank you so much, Mike!!!
