Air Professional Associates, LLC purchased the company that installed my new heating and air conditioning systems this past July. When the weather got cold and I turned on the furnace for the first time, I realized the humidifier wasn't working. Air Professional Associates came right over and took care of it. Apparently, the humidifier wasn't correctly installed to begin with. There was no charge for their visit. I was favorably impressed by their work. If I need service in the future, I will be sure to call Air Professional Associates, LLC again. I recommend them!
