About
After years of experience in Industrial Refrigeration in Europe and 7 years of experience in residential and commercial HVAC in California, two good friends who worked on hundreds of projects together in the biggest HVAC companies of the Bay Area, are finally solid enough to share all this experience and outstanding quality of workmanship with you. Making the process more straightforward is sometimes difficult in big companies. Instead of trying to improve processes in big companies, we decided to launch our company so our customers could get the most transparent and client-oriented experience. We specialize in high-quality heat pump upgrades, furnace and AC installations, and full-service HVAC maintenance, focusing on energy efficiency, long-term reliability, and honest, personalized service. Whether you're upgrading an outdated system, need a new furnace or AC, or just want professional maintenance you can trust — we’re here to keep your home comfortable and energy efficient.

My furnance’s problem was fixed by Andrew, who did a very professional and meticulous diagnostic on every part of the system. Now the furnace is working perfectly , thanks Andrew!

Excellent experience with Ozone. Alexander arrived within the scheduled time window, was courteous (put on shoe covers) and when he learned that I needed an electrician instead of a HVAC service, he said he would check it out anyway. He was thorough when finding the issue (no power to the furnace). Once he was finished installing the transformer, he checked the Google Nest and there was still an issue. He immediately went back upstairs and opened the ceiling to find out what was going on and then explained the options. He was also incredibly organized and clean. Very impressed with the level of professionalism with this company and categorically recommend them.

I recently used Ozone Service and I couldn't be happier with my experience! They responded to my inquiry very quickly and arrived right on time. The team explained everything to me in detail and offered several options for installing a heat pump air conditioning system. They worked very hard, cleaned up thoroughly after themselves, and took the time to show me how to use and adjust the system. I am extremely satisfied with both the quality of their work and the very competitive price. I highly recommend Ozone Service if you need this kind of project done!
