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!

Brian is very easy to work with, his advise about which gas stove to go with was excellent and my parents ending up going with the high-end Regency model. His installers were very good and were easy to talk to about the job and they did an excellent job. I like it when a contractor works with their customers and cares about their company to back up the work done. I highly recommend them and a special thank you to Brian who runs an excellent company! My parents are extremely happy and can't wait on those cold nights to go by to feel the warm heat of their new stove.

This company has excellent products and even better service, and it shows through client interaction. They care about their customers and complete their work in a timely fashion. Best of all they leave the work area in cleaner condition than when they arrived.

Their showroom has items you can't even imagine.

-Furnace
-A/C unit
-Air cleaner and purifier
-Tankless water heater
-Fireplaces (Mantles)

Brian and his team are my go to.
