I’m really pleased with the service I received from DeMarco Mechanical. Their technician was professional and quick, diagnosing the issue with my furnace in no time. They also didn’t try to upsell unnecessary parts, which I appreciate. The only reason I’m not giving 5 stars is because I had to wait a day for the technician to be available, but once they arrived, everything went smoothly!!

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

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 !

Adrian service was excellent

On time, honest, friendly, did a very good job, reasonable price

Thank you so much for your great service and instilling a new furnace in a cold day, highly recommend.

He came, he saw and we hope he conquered!

Always great service. Adrian is the best!
