Mr Oleg and his team were excellent in fixing the attic fan at my home at a very reasonable rate. I would highly recommend the team.

I had an amazing experience with Oleg and Teymur! They repaired my AC and furnace, and also installed a new water heater for me. From the beginning they were friendly, professional, and really knew what they were doing. They took the time to explain everything, answered all my questions, and made me feel comfortable throughout the process. Its hard to find people who truly care about doing quality work, but these guys definitely do. Everything is working perfectly now, and Im very happy with the results. I highly recommend Oleg and Teymur to anyone looking for honest and reliable service!

Before ONzone Heating & Cooling, I had technicians from other companies come out, but either the prices were too high or I didn’t feel confident they could handle my complicated Mitsubishi system. I wasn’t getting clear answers to my questions.
When ONzone arrived, they explained the whole process clearly, answered all of my questions right away, and professionally replaced my AC compressor. Fair pricing, great communication, and they cleaned everything up after the job was done. My system is working perfectly again. Highly recommend!
