Barrus Heating And Air have been taking care of our heat and air system since 2016. They do a fantastic job. This time they unclogged the drain pan for my air conditioner which is located in the attic. We haven't had any problem with it since they finished. I highly recommend them. We've had nothing but good experiences. The servicemen are always friendly and polite. They must be very knowledgeable about what they do since they always fix any problem we have quickly. I would consider Barrus Heating And Air a great company to do business with.
