We are so happy with the service, support and product that we received from Cozy Comfort Plus. Brian was incredible to work with, he took the time to understand what we were looking for and helped us with the designs and what the best fireplace for us might be. He is extremely easy to work with, very easy to communicate with and so fast and responsive!

Everything happened exactly on schedule and as planned. It was a well oiled machine!! The crews that were here to build everything were super friendly, kind, courteous and knowledgeable.

Highly highly recommend to all 😀👍

When my furnace broke down last winter, we were without heat for two weeks while the HVAC company sourced the parts from the US. I wanted to install a gas fireplace insert to replace my existing gas log set and to act as a backup heat source (e.g. furnace breaks down again, no power). I had a number of questions about the various gas fireplace inserts (e.g. size and fit in my old fireplace) and I contacted several HVAC companies.

I found that Brian from Cozy Comfort Plus to be the most helpful and he also gave me the best price. I was home at the time and I saw that the Cozy team did a great job installing the gas fireplace insert (e.g., assembling and fitting the insert, bending and capping the chimney, etc.). If you are looking for a gas fireplace insert, I would highly recommend that you give Brian a call.
