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!

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 😀👍

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!
