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!

Brian and his team did a fantastic job replacing our tankless hot water heater for a fair price. Great work on a complicated job requiring new piping to be installed through our attic and roof. Would recommend this company to anyone!

Raymond and Ali were professional, and a pleasure to meet. They arrived on time, did the work (hot water heater removal and installation) efficiently and expertly, and did a great job of cleaning up afterward. This has been my consistent experience dealing with Cozy Comfort Plus over the years. Brian, Liz, Jay... all the team members I've interfaced with are top-notch. Highly recommended!
