I always recommend Comfortmaster to others as a great company. I'm a caretaker on several properties and use Comfortmaster quite often. Some of the major projects they have done for me include installing a furnace on a property and fixing an air handler on another property. Comfortmaster just gave me a new proposal for a dehumidifier unit that I am considering. I am pleased with their customer service and count on their professional expertise. Five stars for Comfortmaster!
