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.

Our AC worked well with no issues but called just for an inspection and maintenance check. Denis was quick to respond took a look and was quick to diagnose that it wasn’t in fact working efficiently. He recommended a cleaning and coolant top off, he did it right away and now our AC works even better than we thought. He arrived early and clean up after himself, would definitely call him again for any future HVAC needs.

Parents furnace went out. Have been very concerned about the gas smell that was coming from the air vents. Immediately put in my thumbtack request and received a text at 10 PM that night and they were able to come first thing in the morning and fix it. Parentals are very happy. Thank you for the professionalism and quick turn around time!

Denis was very responsive and professional. He repaired our old wall heater and came back the next day to ensure his work was complete and that we were satisfied. I would definitely hire him again!
