I had contacted this company on Oct 5th, 2023. They are very helpful and responsive. They helped with quick installation and the men worked tirelessly through the process for great success. I got heating pumps installed in multiple places that came with a remote for each. Excellent services from Brian, Kaz and Hamid. They work very well and understands the business qualities.

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.
