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.

Pointed put the problem to me right away. Denis helped me fix and check my AC unit all the way through. I am very satisfied with the result. 10/10 highly recommend and I will call DZO HVAC GROUP if I need help again in the future!

On a recent very hot day we had a problem with our AC. DZO responded very quickly and Denis, their engineer arrived soon after. He was professional and communicated the issues and our options/costs promptly and gave good advice. He switched out parts in the faulty unit quickly and the house was cooling within an hour, which was a great relief! I would highly recommend DZO’s service and thanks especially to Denis - who kept a cool head on a hot day!

They arrived on time and thoroughly checked our central ac system finding low Freon. We have an older single unit central ac system. Within about 40 minutes including a detailed review inside the air handler / furnace and the condenser measurements, they diagnosed the problem and fixed it for less than $300.00. The repairman was very professional and clean and I will definitely use them again.

With short notice, Denis repaired several problems with my AC. After he inspected the unit he found it was a bigger job than expected, but he went above and beyond to find the needed parts and repair everything for me in one afternoon. I feel grateful that he took care of this problem so quickly, saving me and my family from the upcoming heatwave in my area. Highly recommend his work!
