Gas Furnace / Forced Air Heating System Repair Service
We have a Victorian house with a heating system over 100 years old. The old ducts had to be removed and replaced before either turning the furnace back on or replacing it. We hired Dennis to handle the installation, since he was using a 3rd party to do the abatement, he suggested I talk directly with the abatement comoany, which saved me around $500 and expedited the project.. Dennis installed the new ductwok and also tuned up the old heater, so it is safely warming our home.

Very knowledgeable and cut through the BS immediately. Understood the problem and solution. His work was completed on time as promised and saved me money by informing me of other repairs the company that gave me the 1st estimate were not needed after inspecting my AC.
Highly recommend Dennis - Owner / operator - HIRE HIM

I would definitely recommend Dennis‘s heating and cooling company. Dennis came out repaired my air condition unit. I was told by other companies my unit could not be repaired, I need a new one, or if the unit is over 20 years old we can’t repair it. All I can say is, if you have a problem with your air condition unit call Dennis’s heating and cooling company!
