I have needed immediate service and repair for the Heat Pump in my Condo in Mississauga three times over the last 8 years. Every time during the heat wave in the summer, and also Ice storm in the winter. Cozy Comfort Plus was referred to me by a family member. Since then Cozy Comfort Plus has always been the place for me to go to for professional and great technical service and repair, even for maintenance on my Gas fire place. As I needed to keep my tenants happy and satisfied. They helped me save thousands of Dollars, by recognizing the problem and replacing the faulty part on a cheap Heat Pump installed by the original builder. Cozy Comfort Plus truly stand to their name. I have referred them to my elderly parents also living in a Condo and they had the same great experience I did. Their technicians are experienced, professionals and extremely customer friendly. In all occasions, they treated it as if their own. Thank you Cozy Comfort Plus

We've had Cozy Comfort Plus over at least a couple of times to instal and maintain our furnace over the years for our place in Mississauga. They have gained our trust and exceeded our expectations as customers. They repaired our heat pump that has been working exceptionally since their visit. They also fixed our AC on another occasion. These guys are the best in the business and honestly such wonderful people. If you were looking for a trustworthy organization with integrity, I would highly recommend contacting Brian and team at Cozy Comfort Plus. I'm sure these people will take great care of you, just as they did for us!

I am very pleased with their services. They help me build my new fireplace which was actually to correct the previously wrong built by another contractor. Brian is the chief designer for my fireplace, then he referred a good contractor Martin to build the fireplace. Because they did such a good job and they are bunch of caring people, I hired them again to help me disconnect my gas BBQ from the main connector. The Gas technician they sent did an excellent job. Thank you Brian and your team. I would highly recommend their services.
