DeMark Home Ontario

We have just had new furnace and ac installed in our house through Demark Home. Booking was quick and easy. Their customer service is great - very responsive and the technicians are so polite. If you need new furnace, ac or both this is the only company to call. I highly recommend them! Thank you guys for outstanding service!

DeMark Home Ontario did an amazing job replacing my water heater. Fast and reliable service. Guys are very professional. Thank you.

I’ve purchased the furnace from them before didn’t have any issues with it only one time had a complication their service team attended for your charge did the maintenance. All in all there have been always very professional and the quality of their products was good so I decided to purchase a tankless water heater from them. Same as usual, I put a call, technicians came in within one or two days, and the installation very professionally, were very cognizant and careful did not damage anything did the work within a reasonable time. There were extra services required of addition of a gas pipe which was done free of charge and even when I insisted to pay for it Mike told me that he’d rather honor the initial price that he gave. This is the kind of customer service I look for. Highly recommend working with them, looking forward to purchasing more products in future from them if I need to.

Overall highly professional business system or service is top-notch. They should pride themselves of the services that they provide and the products that they sell.

My family and I had a great experience with Demark Home’s service. They installed a new furnace and ac system in our new house. Their prices were reasonable, installation went great, and their customer support was very helpful throughout the process. Installation team showed up on time and did everything cleanly. Strongly recommend this company

This company was super helpful from the start, calming me down when I had no heat and arranging for the furnace to be replaced asap. The 2 men who installed took about 2.5 hours and were very friendly. I would recommend this company to everyone!

Great interaction with the sales rep and was even more pleased with the install crew. They did a great job in a timely fashion and I would highly recommend them.
