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.

I had the most fabulous experience with Cozy Comfort Plus! Brian was very responsive for my first outreach all the way through to the completion of my beautiful fireplace! I live in a condo and as such, things are not straightforward when it comes to having work completed. There were a few extra hoops to jump through but Brian and his team were very diligent in ensuring that all the fittings were correct. I was so happy with my experience that I had them replace my furnace and add a smart home thermometer as well! I would highly recommend Brian and his team for their knowledge, skill and excellent customer service!
