Nice young man named Alex came to the house recently and performed a complete duct cleaning and a check of the furnace as well. He gave me honest answers to all my questions and explained exactly the type of work he would perform and how it would be done. During his visit, he also showed me photos of some of the ducts both before and after the cleaning. This employee and the company he represents have a very good work ethic and I would highly recommend them. I can certainly feel the difference in the flow of air in my homes.
