Make Marx Your First Choice Read Some of Our Five Star Reviews

    "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!

    Val R.
    "Super work!"

    Marx Mechanical Heating and Cooling did a wonderful job in repairing our ductless heat pump system.  I highly recommend the company.

    Leland D.
    "I would highly recommend Marx Mechanical!"

    Marx Mechanical replaced our old furnace with a new heat pump which has kept our house warm all winter. They worked with us to find the perfect system for our home and our unique needs.

    Serena E.
    "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.
    "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.
    "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!

    Brian 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.
    "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!

Frequently Asked Questions

The scope of a boiler project depends on your existing heating system, installation requirements, and equipment choice.

How Long Does a Boiler Installation Take?

Most residential boiler installations take one to two days, depending on the complexity of the job and whether the existing infrastructure needs modification. We’ll provide a clear timeline during the consultation.

Do I Need a Permit for a Boiler Installation in Uxbridge?

Yes. Boiler installations in Ontario must be completed by a TSSA-certified gas technician, and a municipal building permit may also apply depending on the scope of work. Our team handles the permitting process and TSSA compliance from start to finish.

What’s the Difference Between a Boiler & a Furnace?

A furnace heats air and distributes it through ducts. A boiler heats water and distributes it through pipes to radiators, baseboard heaters, or radiant floor systems. The right equipment depends on the distribution system already installed in your home.

How Long Will My New Boiler Last?

Annual maintenance supports ongoing boiler care. Regular servicing through our Comfort Club supports ongoing boiler care.

Do You Service Areas Outside Uxbridge?

Yes. We serve Port Perry, Stouffville, Durham Region, York Region, and GTA cottage country in addition to Uxbridge.
