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.

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!

Second time using this company and I recommend them highly. Product was explained, price was comparable, if not better than other companies. Installers were pros and work was completed on time. Very happy customer.
