DeMark Home Ontario

Searched around many companies to upgrade my hot water heater and came across demark home ontario. They had great reviews so I gave them a try. The service I received was amazing, their staff and technicians are very friendly and knowledgeable. No wonder they have such good reviews!

Received great service from Demark Home Ontario when installing furnace and air conditioner back in March. They did a great a job, I really like their technicians. Also already got a rebate from government so they were very fast and efficient in processing my documents as well. Thnx

Such a good job in a short time, living the place tight and clean. Good price for the job done. Thank you!

This is the second time I have used their service after having recently moved into another home. Both times their services was seamless and expeditiously executed. As a matter of fact they went beyond their service scope this time when it came to my water heater instal. They stayed very late into the night till the job was properly completed due to a mistake my house contractor had created making their work difficult; their effort to correct the situation so the instal gets done right was very much appreciated!

From the first customer service call to the representative who came to my house it was a pleasure, this is the 3rd Furnace install in the house and by far the best installation as the technicians did a great work and when they were gone it's like they were never there. Highly recommended!

When my old waterheater broke I shopped around for an upgrade. DeMark Home Ontario was very easy to find and I got to the right person in no time, without talking to answering machines or waiting on the line forever. The upgrade was scheduled for the next day. The installers did a great job, cleaned everything up and even returned the old unit to Reliance for me. Overall an exellent jon on all fronts. When my furnace and AC will be up for an upgrade I know what to do.

Thank you.

Thank you Demark Home for fast service, for installation of the new water heater rental. Your rental rates are good, your technitian staff was friendly. After working they have cleaned the working space.

Very fast service. Very professional and super clean installation. Old furnace was broken right before the cold days. Company found the way and time to replace the furnace almost immediately. Installers were nice and friendly. I highly recommend this company.

We installed new furnace from demark home and very happy with the company, and especially want to thank John. Amazing job installing the equipment and I would highly recommend them to anybody who is looking to replace the Furnace.

Installed high efficiency propane furnace, air conditioner and new hot water heater with DeMark Home Ontario this week and we are very pleased with the service. Technicians did a great job and finished installation of all 3 units in one day. The job was done very neat and professional and i would recommend this company to everyone!
