Pro did everything right. He was honest with his suggestions and was courteous and very knowledgeable. Even tested CO after installation to ensure safety and explained how existing thermostat actually works. I'd hire him again.

Dennis is a good guy and a professional. He showed up promptly on time. Analyzed the problem as my heater's thermostat failed. He had a replacement part, ready to go but it wasn't WiFi capable. I decided to get a smart thermostat from Best Buy and asked him to return to install it. He did and my furnace is heating my humble little house. Thank you Dennis, job well done.

Dennis was always on time, whether it’s to give me an estimate or to install my furnace. He kindly answered all my questions. I really needed to change out my 20+ year old Carrier. Within 2 days of me saying yes, he was able to install my new furnace. I purchased new Comfortmaker. He didn’t gouge me and gave me a great price. Installed a new switch, so I wouldn’t have to fiddle with my circuit panel. Installed smoke and carbon monoxide alarms, protecting my house and family. Very thorough. I would recommend him to my friends and family.

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!
