The maintenance crew at Cali HVAC is top-notch. They showed up right on time, did a full inspection of my system, and even cleaned out the filters. Everything is working great now, and they gave me tips for the future too. Solid service all around!

Honest Diagnosis and Thorough Explanations Oct 16, 2025

This is the 3rd time I have used Cali HVAC. They come quickly to my house, give honest diagnosis and give thorough explanations as to what's wrong. They also call later in the week to see how the system is working. We will be using their services in the future.

Totally Professional and Reassuring Sep 23, 2025

Tom, the technician/plumber for Cali HVAC, was here as scheduled, was totally professional, and eagerly answered my many questions. This was not a follow-up call because all previous HVAC work had been completed. I just needed some additional plumbing work to be done in my home, and the owner graciously accommodated me. How reassuring to know I can rely on this company whose owner actually answers the phones! Thank you, Cali HVAC!

They Are a Plumbing Company Dream Team Aug 29, 2025

As has always been the case, Cali HVAC came through once again when I needed plumbing services. The Contra Costa Water District had informed me that I had a continuing leak in the home, and the rep sent out to inspect could not determine where the leak was. So, I called Cali HVAC, who came the next morning, pinpointed the problem, and quickly repaired it. They had installed my HVAC system last year, and it meant so much to have a reliable, courteous, totally professional plumbing/HVAC company. I can truly say here that they are a plumbing company dream team. And get this: when you call, there's no AI robot, no message machine, no waiting for a call-back. Daniel, the owner, actually answers the phone!

Finding CALI HVAC Felt Like a Win Aug 14, 2025

After dealing with a few sketchy HVAC companies, finding CALI HVAC felt like a win. They showed up when they said they would, diagnosed the problem fast, and didn’t push for extras I didn’t need. Honest folks.

Charles Baker

They Are Very Knowledgeable Aug 12, 2025

What I like about them is they are very knowledgeable, but more than that, they care about getting the job done to our satisfaction. They followed up on whether it was working perfectly, and came back quickly when we needed more. Several other HVAC companies came out, but didn't really fix the problem, or follow up. I highly recommend them.

Outstanding Service Feb 22, 2025

Outstanding service! Dan and his team from CaliHVAC made the process from start to finish seamless and with high quality. They were also very quick in identifying and resolving a communication issue that was plaguing for a very long time, especially when several other dealers couldn't get to the root cause of it.

Greatest HVAC Service Ever May 14, 2024

Greatest HVAC service ever. Was on time and honest about my options. As a woman, it's difficult to find someone to help when you have a budget. He fixed my furnace and AC without forcing me to replace them as other service companies have advised. I will always call them and refer my friends.

Our Go-To HVAC Contractor Nov 30, 2023

With over 15 years of property management experience, I've cultivated a network of reliable contractors in each area. CALIHVAC stands out as our go-to choice for all wall furnace and centralized AC service needs, consistently delivering exceptional work ethics, quality workmanship, and reasonable rates. Daniel, in particular, has consistently impressed us with his expertise and dedication, making CALIHVAC our preferred HVAC contractor over larger local companies, often with inconsistent service quality depending on the tech they send out for the work.

Paul Yap

I Couldn't Be Happier With the Service Mar 12, 2026

I recently had my furnace and air conditioner replaced, and I couldn't be happier with the service. From the start, communication was excellent; Daniel was incredibly responsive and answered all my questions quickly. The team arrived exactly on schedule and managed to finish the entire installation in a single day, just as promised. Their pricing was reasonable and honest, with no hidden fees or surprises at the end. Beyond their technical skills, the crew was very friendly and Daniel took the time to explain exactly how the new system works. They also did a great job cleaning up, leaving no debris behind. If you’re looking for a professional, tidy, and punctual contractor, I highly recommend them!
