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.

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.
