I had my tankless water heater replaced through Cozy Comfort Plus. Brian was very helpful and his technician did his best to ensure the new model would fit the tight nook that the original one was in. The team installed the new heater quickly and ensured the location was clean afterwards. Overall, I was very satisfied with the installation and service.

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.

Maury from Cozy Comfort did a fantastic job of examining the functionality of my furnace and cleaning the major components. He tested my furnace to make sure that it would run efficiently in the winter. My humidifier was cleaned, the drip pad replaced and settings properly set up. Thank you Maury for your effective care. thank you Cozy Comfort- you are a company that has proven your worth over the past 25 years that you have looked after my family's heating and cooling needs.
