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

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.
