A repair visit typically includes a diagnostic assessment of the indoor air handler, outdoor condenser, refrigerant circuit, electrical connections, and control system. Our technicians determine whether a fault is isolated to a single zone or affects the full multi-zone system, and they work around your operational schedule to minimize disruption.
Our team is well-versed in Ontario safety and compliance standards, so every repair meets applicable codes. With our Daikin Comfort Pro Partner credentials and hands-on experience across commercial brands, we can source parts and complete repairs efficiently for systems that other providers may not be equipped to handle.

"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!

"The team at Marx Mechanical did an amazing job with my install."
They answered all of my questions, gave honest advice, and put in the extra effort to fit my new Daikin air handler into the very limited space that was available.
Dennis P. -
"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.
Karen B. -
"Their staff and technicians were exemplary."
Marx Mechanical responded quickly when our furnace broke down on a cold day in December. They quoted a good price and installed the new equipment promptly. We were impressed with their professionalism and their promptness in dealing with the issue.
Robert A. -
"Great team, great products, great experience."
The systems are exceptional. I wouldn't change a thing about the experience and I would highly recommend Jason and his team at Marx Mechanical for any such work. Solid pros, excellent experience from start to finish!
Daniel B. -
"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.
Dave M. -
"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!
