We encountered a problem with our heater not blowing any air. We initially hired another contractor who charged us $400 to replace a panel, but that didn’t resolve the issue. They then quoted us $3,600 to replace the motor and other components. We decided to seek second opinions…

My HVAC system wasn’t operational, and I was recovering from surgery. Ozone Service sent someone right away. The owner was courteous and warm to the point I asked him if he was AI! He sent someone the same day to fix the HVAC. Andrew was knowledgeable, very professional, and we a…

Quick response and professional service, which is all you really want during an HVAC failure in the heatwave season. They were one of the few that offered a free diagnostic with no obligation, so I ended up going with their repairs. The entire process was seamless from start to f…
