Is air duct cleaning effective and worth the cost?

Answer 1

The effectiveness of air duct cleaning, like most things, depends on your goal or expectations.

Are you trying to improve indoor air quality? The verdict is out on whether dirt and other stuff in the air ducts will ever reenter the rooms of your home, but it's definitely worth trying if your home tends to be unusually dusty. And if it's about Allergies or Asthma, then air duct cleaning alone isn't enough no matter what - it has to be seen as part of an overall management plan. Your air ducts are only one possible source of pollutants in the home. To improve indoor air quality, you need to remove or address the source of the air pollution, as well as increase ventilation so it can't keep building up.

And is it worth the money? If air duct cleaning will accomplish your goal, then it's worth it.
