I have been a Komfort Heating customer for five years and first used them to install a furnace and AC unit. I was very pleased with their professionalism and the installation went exactly as planned. I have since used them for my spring and fall service calls and they have consistently been dependable (always showing up on time and calling when they are on the way) as well as thorough and competent. I highly recommend Komfort Heating and I trust them.
