DeMark Home Ontario

We had to replace our old A/C for the new one. We got quotes from a bunch of other companies and decided to stick with the De Mark. The service was great. The installation was done the next day after I filled a request online. The installer named David is a professional guy and did a clean and prompt job. Special thanks to Mike for the great business and guidance. I definitely recommend this company to others

Very professional and easy to book. We chose DeMark Home to have our 25 year old furnace replaced with a high efficiency one.  went through a couple of companies but Demark gave us a great price and responded quickly to our request. Their booking was super easy. 2 technicians were very nice and professional, knowledgeable and did a wonderful job. highly recommend

Its been our 2nd time working with Demark. They replaced our water heater to a tankless last year and this time we called them for our furnace issue. Furnace was unrepairable and Demark offered us great rent to own program at very reasonable and affordable price. Booking process was easy and quick, installation went smoothly. Technicians did wonderful job.

My 15 years old furnace started to make loud noise. I had some very positive experience with DeMark home, when my AC broke down, so I decided to ask DeMark home for installation of new furnace. It was done in one day by very professional team. I couldnt be more happy and satisfied with my new furnace.

We found what we were looking for at a great price and attentive customer service.

AMAZING experience! My water heater suddenly stopped working. I was referred to DeMark by a friend. In one day I had a brand new, energy efficient tankless system installed. Installation was quick and easy and no mess! I really appreciated the prompt, reliable service. Most of all I appreciated only one day of freezing cold showers! :) DeMark will be my only choice for home services.

i decided to change my water tank with a tankless water heater so I called Mike and from the start he was very helpful, explaining everything. I got a call shortly after with one of customers services to schedule a day to install and to confirm everything that Mike and I talked about. The very next day they sent their technicians to install a brand new top of the line tankless water heater....didn't take them long to install and in less then 2 hours my hot water was working again. They cleaned everything up and they even took the old water tank.
I'm very happy with how everything turned out.
I recommend them 100%.
Thank you
