Duct cleaning scams
You may have read reports of people being scammed by fraudulent cleaning services that either overcharge or misrepresent the amount of cleaning needed and charge more money. Many of these companies use what is commonly known as the “bait & switch” technique. Basically, they advertise a complete duct cleaning for only $49, yet by the time they are through with their service the price may have climbed to $500 or more dollars because of services they didn’t mention.
Some companies may not clean your ducts completely. It is very important that every inch of the system is touched with the compressed air tool. If the system is not completely cleaned it can actually cause more problems than before it was cleaned. This can happen because of the dust being loosened and pushed into piles inside the system. The clumps will break up and be pulled further into the system or be pushed out the supply registers when it is turned back on.
