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.

From installation to maintenance, Cozy Comfort Plus Inc. provided us with prompt, quality service. It took under a day to install our Mitsubishi split-type air conditioner in May, 2021. This week, they attended to cleaning our unit’s filters in less than a day’s notice. The technician explained how to remove, clean and reinstall the filters ourselves which will save us money down the road. I highly recommend Cozy Comfort without reservation.

Fair, professional, efficient and friendly company to deal with. Great customer service. All work was performed on time and way above our expectations. A company that communicates well, is true to their word, cares about their customers & focuses on delivering an excellent experience. We had the following installed: heat pump, furnace and smart thermostat. We also got attic insulation added & our tankless water heater flushed. Highly recommend this family-owned business.
