On time and efficient!Posted on Michael TrangTrustindex verifies that the original source of the review is Google. Full system replacement. Very affordable after I got 3 different quotes. ~6 hr install on a Saturday and thorough walkthrough explaining what they did after the job was complete. Eli and Raphael were great.Posted on JC VillarrealTrustindex verifies that the original source of the review is Google. Very happy with the servicePosted on Vineetha MuddaTrustindex verifies that the original source of the review is Google. Outstanding Service & Honest Expertise! Our AC unit suddenly went down, and the maintenance company we initially called tried to convince us that a full unit replacement—costing $30,000 to $40,000—was the only solution. Seeking a second opinion, we reached out to a few other companies, all of whom focused on the control board as the issue. Thankfully, On Air HVAC came out for another assessment and quickly identified the real problem—a faulty connector. Eli was incredibly professional, thorough, and took the time to explain everything clearly. He had our AC back up and running in no time, saving us from an unnecessary and costly replacement. We truly appreciate their honesty, expertise, and efficiency. Highly recommend On Air HVAC for anyone in need of reliable and trustworthy service!Posted on John BarnhartTrustindex verifies that the original source of the review is Google. March 2025 update: Once again our semi-annual service appointment was completed perfectly. And our HVAC unit continues to work well. We're happy to be customers. *** October 2024 update: We just had our autumn service appointment, which was completed on time and completely to our satisfaction. *** Original review: We had a great experience with On Air. We contacted them initially when our old system began acting up in December. They provided competitive quotes for repairing and replacing the old system. We decided to replace, and they ordered a new, highly rated system for us. When the system arrived, we scheduled the installation. The crew arrived on time and completed the work flawlessly. We are completely satisfied.Posted on Michael OakesTrustindex verifies that the original source of the review is Google.

He resolved the issue. I'm very happy with the service.
