Outstanding. We got a "red tag" from Enbridge for a leak. Cozy Comfort's experienced technician came by and fixed the problem in less than an hour for a reasonable rate.

The company whose installation caused this problem in the first place quoted me over $1000 for a rebuild of the exhaust vent which is just PVC pipes and would have left us without hot water for over a week. I'll go with Cozy Comfort Plus for all my heating & cooling maintenance from now on.

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.

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.
