I had DeMarco Mechanical Services clean out my HVAC ducts and vents, and I couldn’t be more impressed! The team was professional, timely, and thorough. They explained everything they were doing and showed me before-and-after photos, which was a nice touch. My home feels fresher, and I’m breathing easier now that the air quality has improved. Highly recommend their duct cleaning service!

Adrian at DeMarco Mechanical Services responded quickly to my call and offered me a fair price for his services. He was punctual and professional, I will be calling again should I need any unit maintenance or repairs.

Hi great service by Adrian. Our heating system stopped working and house got very cold right away. We live in east end Adrian drove to Brampton to get a Lennox part not available in Markham. Totally grateful. Nice honest individual. Fast repair furnace up and running better than ever first morning he attended. Amazing all I can say house toasty warm furnace more quiet. I wish more people like this around. Great work Demarco and Adrian. Much success in future. Toni

Adrian did some amazing work for me at my house and I would highly recommend him. He is very knowledgeable hardworking and extremely fair in his pricing. 10/10 he will be getting my business from now on!!

Services and installation they were reliable trustworthy would highly recommend their service good job 👍🏽

Adrian was informative and efficient. A great help.

I am very grateful to DeMarco for fixing gas leak at my landlady's house. We called several companies. Only one came, but was not able to fix it. I called DeMarco next morning. Mohammed came to rescue us. He fixed the gas leak, checked our furnace for free, pushed back washing machine in the hall. If it was not DeMarco, we would still have no heat and no hot water. I highly recommend them !
