Brian once again helped me with my project. Before I have installed a gas fireplace and this time I have installed an LG heat pump with 3 indoor heads. We had an amazing experience with Brian and his team for both projects from quote to installation. Brian is experienced, patient, reliable, and provides great friendly service. He’s also tells very interesting life stories which makes enhances the whole experience. All my future business is going to his company. Thanks again Brian!

The 30+ year old gas fireplace in our condo was just replaced with an electric one. Not a simple job, however, Hamid from Cozy Comfort, was very resilient and knowledgable in figuring out how to do it efficiently. He answered our questions and made sure we were satisfied before he left. I would also be very happy to recommend Brian Kar who first came to talk to us about the various options.

We were looking to replace A/C, furnace and water heater and had a number of companies provide quotes. Brian of Cozy Comfort Plus was the most engaging person we met and most importantly, the person we trusted the most. His price was very competitive and we decided to go with him. His team of four men, led by Mir, came in and got the job done in one day. We are very happy with the Lennox equipment and the professional installation job done by Cozy Comfort Plus.
