DeMark Home Ontario

I used Demark Home service twice now, last summer had a problem with AC, and now with furnace on the coldest night in decades.Really appreciate such a late service. Already referred people to this company.

New furnace and hot tank installed. Great service and price.

Fast HVAC Company arrived on time. I had a new water heater installed. Friendly service man Jason. I would highly recommend this company. Thank you.

Installed new furnace with demark home, great service, amazing job...

What an amazing company. It was such a pleasure to deal with them. Maria was supper amazing and knowledgeable i recommend you to ask for her if you call this company for a service, but at the same time i think everyone who works there is highly trained. They gave me recommendation for the best furnace and air conditioner suitable for my house needs which was a complicated installation due to the way my home is, but their techs were very efficient and did a superb job. Recommend this company
