 Trustindex verifies that the original source of the review is Google. Great experience during a heatwave! Ilya arrived right on time, quickly diagnosed the AC issue, and explained that my parts were covered under warranty. He also gave me clear advice on potential future issues with my overall system. Very honest, knowledgeable, and punctual. Highly recommended!

 Trustindex verifies that the original source of the review is Google. I got a new furnace installed with Ozone Service and was helped by Konstantin. He was excellent, patient and on top of everything, and the installers were very competent and all went smoothly. I would highly recommend Ozone Service and Konstantin.

 Trustindex verifies that the original source of the review is Google. Called OZONE late Friday night and had Andrew out by 8am Saturday. He diagnosed the failed starting component quickly, had the part on the truck, and had the system running and verified cold before he left. On time, no upselling on a old unit, one-year warranty on the repair. Exactly what you want from a service call. Highly recommend.

 Trustindex verifies that the original source of the review is Google. Konstantine and Paul (and one other) were excellent.  Price as the best among 5 quotes.  Professional.  Replaced our 3.5 ton carrier gas+AC with a daikin 3.5 ton heat pump in 2 days (all to code with permits, inspectors pending).
