I have found my new HVAC company! Advanced Heating & Air Conditioning in Temecula got my business by answering their phones and being knowledgeable and kind. They got my business because scheduling was easy during this 2026 heatwave means they hired right. And finally, when Danny showed up it was once again a knowledgeable and kind technician that was ready to work. Thank you for keeping us cool.

They were able to get me in the same morning I called. The technician arrived early in the estimated time window and fixed my AC issues in 30 minutes. Great services and amazing timing.

We’ve been using Advanced Heating & AC for years, and they have always provided excellent service. Most recently, they quickly diagnosed and fixed our air conditioner, getting everything back up and running in no time. They are professional, reliable, honest, and always a pleasure to work with. Highly recommend them to anyone needing HVAC services!

First of all, The lady that took my call was knowledgeable about HVAC. I had an email for the booking and to confirm the next day appointment with the time. Matthew showed up right on time. I explained the situation to him and he went over the unit to check for issues. Unit was good, He went into the attic to go thru the whole system to check for shorts ,breaks etc. The issue was the condensate drain thingy was not draining and it tripped a safety shut off and shut down the system. Had the drain cleared out and am now enjoying the a/c again. ZERO UPSELLING, everything was explained to me what and why it happened. This is the company you want to call when your AC dies. The work was priced fairly and Matthew actually knows his trade. I will share this service company with my neighbors.
