installation of a new A.C. unit was done in June, and I'm extremely happy with the workers from A-l Guaranteed. The unit works well, I have never had any issues with this company, and have been using them for approx. 30 years.

A-1 Guaranteed Heating & Air is the absolute best in the biz! We were searching for a reputable HVAC company to install a new heat pump system for our home. We interviewed several companies and chose A-1 because they gave us a great price, had the best warranty, and were the most qualified to do the job. The install was not easy as the system and ductwork had to be installed in an attic with areas that were difficult to access. From the start to the finish, the entire crew was on point and professional. Everyone that we interacted with was helpful and easy to work with. They even gave us guidance to file for the rebates that we qualified for. I can’t say enough... read full review

Jorge was on time, communicated well and completed my ac service in a timely manner. He took the time to explain things about my unit and was up to date on the latest regulations coming to California. I've used A1 for decades now. Highly recommend!!
