Your #1 HVAC Company in The GTA


We had a problem with our AC and called three different HVAC places and nobody was returning our calls. Adrian was great, provided great service and found the leak and fixed it immediately. We would highly recommend him.

Adrian assisted us on a Sunday afternoon after a gas leak was detected.He subsequently repaired our AGA oven when it failed to work. Very satisfied with his work and communication each step of the way. It was a pleasure dealing with DeMarco mechanical and would refer them to anyone.

Professional, knowledgeable & courteous staff. Being a holiday & busy with other appointments, they visited us at their earliest available time. The charges were reasonable & transparent.

He is very knowledgeable and professional and has good advice and guarantee for his service and product. I will for sure call him in the future if there are other problems with other roof top conditioner.

We have worked with Adrian before and called him to replace an old split unit in our master bedroom. Adrian does great work at a very reasonable price and we are very happy with the new AC.
