Comfort Quest was referred to us by a realtor friend who's clients recommended Comfort Quest. We had our furnace/filter/humidifier replaced as well as our water heater (new tankless to replace old tank). We were more than impressed with their speed of service and flexibility of meeting us at night ... and, did I mention their pricing was fantastic!
We've since renovated our basement and had Comfort Quest come back to clean/service the furnace. Again, service was speedy/professional and pricing great.
We recommend Comfort Quest to all our friends.
