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.

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.

Denis was great! We woke with no heat, he responded quickly to my request on Thumbtack, and arrived within a couple of hours. He identified and fixed the problem quickly, and now we have heat again! I won’t hesitate to use him again in the future and do recommend him to anyone who needs HVAC help.

Responded within minutes and was available at the time I needed. Came in and tested things to make sure he pinpointed the correct issue. Fixed it retested and made sure the heat was perfect.

Couldn’t ask for better service! Returned from my deployment with the US Army and our HVAC system was not working with a new Google nest thermostat. Dennis fixed all the issues and got our HVAC system back up. Professional, punctual, and had everything he needed to get the job done.

Denis quickly identified the problem and fixed it just as fast. I’m very grateful for his prompt response — especially in such cold weather, when I could have been left without heat. He was very polite, professional, and understanding. Thanks to him, my furnace is working again. I highly recommend this company.
