I've been a client of Cozy Comfort for 15 yrs. for any HVAC need or service.

My AC broke down in the heat wave and could not be repaired. I called and talked to Brian @ Cozy Comfort.
Explained I was looking for a specific Carrier model and a humidifier as well.
He managed to find it and had both installed by tech. Alex and his crew within a few days. They did a good job and took all garbage with them.

While being installed, other companies I had called for a quote were calling me to inquire what I was looking for. Told them too late!

During this unexpected breakdown in prime summer heat, Brian was patient, quick and fair getting the job done quickly.

These days it is difficult to give a positive review but I highly recommend dealing with Brian at Cozy Comfort for any service they offer.

Cozy Comfort came highly recommended by my parents after they did some work for them. We had a new furnace, water heater, humidifier, and thermostat installed and they did a great job from the initial visit to the final install.

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.
