I called a few other duct cleaners before I phoned Advanced Furnace. The other companies were just a little bit cheaper but when I asked about their equipment, one company had a van with a vacuum and the other one used portable units. I decided that I would prefer to have Advanced come with their power vacuum trucks.

On the day of the appointment the technician arrived right on time and did a great job. I am happy with the service and would definately have them come back in the future.
