Allison Air Conditioning And Heating, Inc.

I can’t say enough good things about Steve and Katie at Allison Air Conditioning in Corona. Mr. Allison has maintained our system for nearly two decades, and when our old unit finally gave out this summer, Steve was there to help us beat the brutal heat before it got unbearable. We’ve known for years that our original equipment was undersized for the home’s square footage—thanks, Beazer Homes—but Steve has always been our go-to guy. In 19 years, we’ve never called anyone else. If you’re looking for HVAC pros who take genuine pride in their work, call Allison Heating and Air. They are absolutely outstanding.

Big thanks to the team at Allison Air Conditioning in Corona for a great installation. We chose you based on the solid advice we received, and the results speak for themselves—the new unit is running smoothly and the noise reduction is noticeable. Relocating the furnace site was a smart call. A special shoutout to Greg, Bryan, and Ray for being professional, efficient, and respectful of our home throughout the process.

After living in my home since 1981, I was amazed by the immediate improvement in comfort brought by the new Carrier system and ductwork. I confidently recommend them for anyone needing reliable HVAC services.

Highly recommend Allison Heating & Air! The installation crew was incredibly tidy and professional. Steve is thorough and gives honest options without pushing extras.

Steve, I wanted to share how thrilled I am with my new Carrier furnace and AC unit at our home in Corona. The service and equipment quality have been outstanding.

You provided a clear, itemized quote with no hidden fees, the installation was quick and smooth, and the equipment is top-notch. I am completely satisfied with your professional approach, and your crew did a fantastic job. You’ve exceeded all my expectations for a new HVAC system, and I’ll definitely call Allison Air Conditioning for all my future heating and cooling needs.

I can honestly say this is the best service I have ever experienced. Katie, who handles sales and admin, is fantastic—she is always accommodating, pleasant, and eager to help. And Steve, the owner and an incredible AC technician, really knows his craft. I have been relying on Allison Air Conditioning in Corona for more than two years now and would recommend them to anyone. I am so satisfied with the work they do. Thank you!

Big thanks to Allison Air Conditioning in Corona for upgrading our home with a new Carrier system. Swapping out that ancient 1978 Westinghouse rooftop unit—affectionately known as "The Beast"—along with new ductwork was a huge job, but your team handled the demo, crane work, and installation flawlessly. We got a great price and finished exactly on schedule, even with the cool 30-degree nights. The experience with Bill and the installers, Jeff and Albert, was top-notch. As a fellow California contractor, I compared a few local HVAC companies, and Allison stood out for their expertise, quality products, and unbeatable pricing. Their knowledge is a game-changer compared to those guys who just take photos from your attic to give a remote quote. Don’t make that mistake—come to Allison for your HVAC needs. You won’t regret it!
