I requested info online from a few places I found on the internet. Cozy Comfort was the most responsive, not just with the initial info request, but with back-and-forth calls, emails and a site visit. I wanted to convert my wood fireplace to gas, and Brian guided my through the whole process. He explained the type of unit I needed (gas insert), told me the different brands and models that would fit my fireplace opening, and explained the pros and cons of each.

Within a week of my first call, my new gas insert was installed, and a week after that, the stone mantle and hearth were in. The installers laid plastic to protect our flooring, maintained social distance, and were kind to my curious cat and dog. They walked me through how to use the fireplace once the gas insert unit was in. Also, my original fireplace was about 8 inches off-centre (wall is only 13’, so it was noticeable), and Cozy Comfort centred the new one - it looks stunning.

Thanks for everything, Cozy Comfort! I can’t wait for winter 😄

Cozy Comfort Plus Inc. installed a new high efficiency furnace in our house two years ago and it has been operating perfectly ever since. Their service was straight forward, reasonably priced and good value for money. They even walked us through the complicated rebate program that was hard to understand without being involved in the industry.

I would highly recommend them for your next heating and cooling needs.

Cozy Comfort Plus Inc. is the place to go for all your heating and air conditioning needs. Brian is very professional, honest and trustworthy. He knows what's best to do. We had this company do jobs for us, our friends and relatives and it's always been a pleasure dealing with them.

Our most recent call to them was about our heat pump in our pent house in Mississauga. They already had successfully serviced it a few times in the past and this time around it was time for it to be changed to a better unit. Cozy Comfort Plus again did a fantastic job. We are very satisfied with their work and our experience with them.

Thank you so much Brian and the team!!
