About
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.

He came within two hours and saved me from the heat wave. He was professional, punctual, and communicative and fixed a broken AC.

Denis from HVAC PRO was prompt and immediately assessed the issue with our thermostat, checked out our furnace and made wiring repairs to get our system back up and running fast. I would highly recommend HVAC PRO. Pricing was fair and reasonable and the work was done very professionally.

Denis was amazing! He came to my dental office on very short notice and handled our AC issues quickly and professionally. He diagnosed the problem right away, fixed everything the same day, and his pricing was more than fair. Super reliable, great communication, and excellent service overall. I highly recommend Denis and HVAC Pro — definitely my go-to from now on!

Our central HVAC system died last night (1/10/26), in the middle of winter. I phoned Denis and received a response within 15 minutes. Once here, he quickly and efficiently diagnosed the problem. Denis immediately began working to repair our unit. Additionally, the cost for services was reasonable. I am very impressed with his knowledge base and skills. He also gave great recommendations for unit upkeep. Highly recommend.
