Hao Wang says, "I recently had a great experience with Ozone Service and wanted to share a huge thank you to Ilya and Konstantin.My furnace recently broke down due to a main board issue, and Ilya came out to inspect it right away. They provided very fair and competitive pricing for both a repair and a full replacement. After weighing the options, we decided to go with a new unit.The team scheduled the installation as soon as possible, and the actual install process was incredibly smooth. We did hit a small snag when a circuit breaker tripped, but it turned out to be an issue with our old breaker rather than the new furnace. Despite it being an existing electrical issue, Konstantin and Ilya offered to come back the very next day. They replaced the faulty breaker and made sure everything was functioning perfectlyall at no extra charge!I really appreciate their honesty, the quality of their work, and their willingness to go above and beyond to make sure we were taken care of. If youre looking for quick, professional, and reliable HVAC service, I highly recommend Ozone Service!"See more
