Why do some companies charge more for duct cleaning? We get mailed coupons advertising duct cleaning for as little as $59.00.
Not all companies use NADCA-certified procedures, taking many short-cuts and giving a poor quality job using inadequate equipment. Some unscrupulous companies try to entice you with ridiculously low prices; then they add in the extras once they arrive at your house. They could even try to scare you by falsely claiming you have a mold problem, requiring major expense.
How long does a typical duct cleaning take?

Should new homes have the air ducts cleaned?
Yes, the duct systems in brand new homes are already contaminated with construction debris and drywall dust caused by running the system during construction. This dust should be removed to optimize system operation and minimize dust circulating throughout the home.
Why do you have to cut holes in the ductwork?

feel they can get away with, then often they still do not even do the
What can I do if I feel that I have already been scammed?
If you feel that you have been
overcharged for a poorly done job, you should contact a
NADCA-certified company and explain the situation. We will, for a
nominal charge, inspect your system to see if the work was properly
done; if you choose us to re-do the work, we will then give you a
credit off the final bill. We have even photo-documented shoddy work
to help the customers get refunds from the original company.
