Customer satisfaction is definitely their priority.
From start to finish, professional services.
I had Brian and the Cozy Comfort team look after my mother-in-law's HVAC install a few years ago as well, and we were very satisfied again.

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.
