Introduction
I have been doing HVAC servicing for 21 years and it has become a passion for me. I know all the processes from the inside, my goal is to understand the cause of the breakdown and eliminate it using the most modern and safest methods for health. I won’t just fix a temporary breakdown, I will fix your equipment for many years of service. I have all the necessary tools, supplies expense, modern measuring equipment, my knowledge and experience. And I use all this for my happy clients. My highlight is that I love my job and do it conscientiously and efficiently.

DZO HVAC GROUP was quick to respond when our heater quit on a winter day. The price was fair and the furnace was repaired quickly.

I’m very happy Denis came to fix my thermostat. It turned out. The problem was with the transformer rather than the thermostat, so he fixed that. I was a little uncertain about communicating with him at first, because English is his second language. But he has a very good phone translator that worked well when we misunderstood something. At the end, we were able to joke with each other, and I decided to use him as my furnace maintenance person

We thought we had a thermostat issue but HVAC shelf life is over. Thanks to Dennis who diagnosed the issue and recommended to change the appliance and not to spend on a repair Highly professional and honest business guy 👍👍

Very responsive service!! Background: I ordered a google nest and paid for installation through google services. However, the installation was improper and caused hot air to blow all day and night. I searched for HVAC services and DZO immediately popped up. Denis responded to my request only minutes after my inquiry. He showed up to my residence 1 hour later and fixed the issue in just 30 minutes. Very friendly and helpful. I will continue to use these services. Thank you!
