The work was completed as promised, and the new water heater works well. However, I felt communication could’ve been better. I had to follow up a couple of times to confirm the appointment, and there was a small delay in arrival. That said, the tech was professional, and the price was fair.

I don’t usually write reviews, but I had to for DeMarco Mechanical Services. My boiler broke down late at night, and I honestly didn’t expect anyone to help until morning. Not only did they pick up the phone, but they had someone out in a couple of hours. The technician was calm, helpful, and had the heat back on before sunrise. Total lifesaver.

Scheduling was a breeze, and the team at DeMarco Mechanical was super friendly. They installed a new A/C unit in my home, and the whole process was smooth and efficient. They took the time to explain how everything worked and answered all my questions without rushing. It’s rare to find this level of service these days.

I had an issue with my furnace right in the middle of winter, and DeMarco Mechanical Services came through for me. They showed up on time, diagnosed the problem quickly, and had it fixed the same day. The technician was respectful, neat, and clearly knew his stuff. I really appreciated the transparency in pricing too—no hidden fees or upselling. Highly recommend!

Amazing service. Was very happy with it. Super nice and friendly person. Very experienced and educated in HVAC. Reasonable service price as well. Overall very happy with the service.

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 !
