What Our Customers Say
EXCELLENT Based on 85 reviews Posted on Google Md. Abul Bashar ShantoTrustindex verifies that the original source of the review is Google. Got a full heat pump system installed last month and honestly couldn't be happier with how the whole process went. From the first visit to final inspection, the team was organized and clearly knew what they were doing. What I didn't expect was how much help they gave me with the rebate programs - I had no idea how much money was available until Konstantin walked me through everything. They handled all the paperwork on their end, and my out-of-pocket ended up being significantly less than the initial quote. The system has been running quietly and efficiently since day one. Highly recommend to anyone in San Jose thinking about making the switch.Posted on Google faiqah firzanahTrustindex verifies that the original source of the review is Google. AC stopped working on a Friday afternoon. Called Ozone, they came out the same day, found the issue fast, and had everything running before dinner. No drama, fair price. Thanks guys.Posted on Google Amit MTrustindex verifies that the original source of the review is Google. Very efficient, on-time and fair priced. Thank you.Posted on Google A LTrustindex verifies that the original source of the review is Google. Had a great meeting with Konstantin who explained "AC + furnace" vs heat pump, options, decision points. He presented impartially many technical and practical details and considerations that I find critical in making the right choices. Update: The heat pump installation was completed on time with no hiccups. Aleksander, the lead installer, was great in both the technical side but also explaining to me some very important details of the job and the future use. Definitely recommend them!Posted on Google Mark BernalTrustindex verifies that the original source of the review is Google. Very helpful in diagnostics check.

We needed a completely new HVAC system installed, and we had a great experience working with this team. I’ll admit I’m pretty picky and detail-oriented when it comes to work being done on our house, especially during a major renovation, so I don’t give praise lightly. That’s part of why I wanted to write this review. Konstantine took the time to explain the product options and installation process very clearly, which made us feel confident from the beginning. He was always responsive and easy to reach — whenever we had questions or concerns, he picked up the phone, understood our situation, and worked hard with us to solve problems in a thoughtful and kind way. That level of care meant a lot to us. Since we’re doing a full house renovation, we later needed to relocate some HVAC vents and return locations that had already been installed. Even though this meant coming back to our house multiple times, they were incredibly kind and accommodating about making those changes for us. Special thanks to Alex for going above and beyond — we really appreciated his patience and help, especially since they had to come back more than three times for us. The whole team was professional, responsive, and genuinely cared about doing the job right. Even as someone who is pretty particular, I was very pleased with their work and highly recommend them to anyone looking for HVAC service.Posted on Google Alex PérezTrustindex verifies that the original source of the review is Google. Truly outstanding service and HVAC system. Konstantin and his group are extremely competent professionals who are very fairly priced and honest in their dealings.
