We new that we needed our ducts cleaned out before taking possession of the home due to a large amount of animals that once lived here, the lack of cleaning, and my allergies. After the flooring was installed, Alberta Furnace Cleaning came in to remove the debris. We needed this service more than we realized after finding out that the vacuflow was 200% full (read: 2 canisters worth of pet hair and dirt), and the system on the truck was clogged at least 3 times. We felt so much better knowing that our vacuflow was decontaminated, the chimney was free of creosote, and the ducts and furnace were ready to handle the increased demands of winter. Thanks so much!
