Our Featured HVAC Services in the GTA

DeMarco Mechanical Services Inc. offers a variety of programs that can be scheduled on a regular basis for maintaining your Heating, Air Conditioning, Gas & Air Filtration (HVAC) units. Our team of Toronto HVAC contractors offers top-quality service while maintaining the health and well-being of each of our customers and their installed products. We work with both residential and commercial properties across the GTA.

Preventative maintenance is essential to keep any heating and cooling system running safely and at its full efficiency capability. As units age their components suffer wear, and chances are there will eventually be a failure. Having an annual inspection done by licensed HVAC contractors can mean the difference between you being comfortable and worry free all year round, and waiting for a part for your furnace at -25°C.
