Tankless Water Heaters In Oshawa, ON

"Excellent HVAC company to work with!"

They took time to work with us to get the best furnace/heat pump to replace our 20-year-old furnace. They've checked in with us regularly, and while we haven't had any issues, we know that they would go above and beyond to fix anything!

"Every step was smooth and competently handled."

We contracted Marx to replace our aging oil furnace with a high-efficiency heat pump. They arrived, promptly and prepared, on the agreed-upon installation date, protected walls and floors, worked diligently, and cleaned up afterward. Very professional!

"Bravo!"

The Marx Team came to our rescue when our furnace was on the fritz and installed a new one with exceptional installation standards and had us up and running in no time! They are without a doubt the "Go To" HVAC company in the Durham-York Region!

"My experience was outstanding!"

Each member of the team went out of their way to ensure I was well taken care of. In a world where everyone wants to cut costs by outsourcing and automating, Marx demonstrates the value of personal touch and putting the needs of their clients first.

"Marx Mechanical staff are courteous and professional!"

My furnace suddenly died and Marx Mechanical staff rearranged their schedule to be here the next day to replace my furnace (in a snowstorm). All my questions were answered and they even helped me set up the Daikin app on my phone.

"So pleased to have chosen Marx Mechanical!"

From the initial phone call, to the visit to the showroom, to the install, to the subsequent follow up of such, all the staff (including owner) could not have been more accommodating and more knowledgeable.

"They have earned my trust!"

I received a quick reply from Marx and they were able to see me even faster than promised.  In my conversations with the repair person, I felt that he knew his stuff and provided a lot of helpful information. I will continue to call on them when needed.
