This winter when I turned on my furnace I noticed that I had a significant amount of dust blowing out of my air vents. I figured it was probably time to have my air ducts cleaned. Since Ive often seen Advanced Furnaces big red duct cleaning trucks near my home, I decided to give them a call. The woman who answered the phone was very personable and was patient answering my many questions. After answering some questions about my home she was able to give me an accurate price quote and I scheduled an appointment for the following week. When the appointment time arrived, the technicians arrived right when I expected them to. One tech went right to work hooking up the big vacuum hose to my furnace trunk line in the basement, the other started taking off all my registers and wiping them off. They worked hard for about 2 hours. When they were finished my house smelled fresh and clean little bit like lemon or oranges. I would definitely have this company come back in the future, they did a great job.
