La Crosse, WISCONSIN (WXOW) - There is no scientific evidence that regular duct cleaning improves air quality, but some Angie's List consumers have reported that when they have their ducts cleaned, they experience fewer allergy symptoms and cleaner air.
Air duct cleaning is designed to remove air-borne dust and debris from the air duct system components of HVAC, forced air systems, gravity heaters and other related systems.
Before you hire someone to clean your air duct, Angie's List says do your research. Beware of bait-and-switch tactics that advertise an unbelievably low rate and then immediately start tacking on up-charges or using scare tactics.
"One of the more common things that we hear about with air duct cleaning comes down to pricing," said Angie Hicks, CEO of Angie's List. "It's important for consumers to get written in-home estimates because a lot of times air duct cleaning is based on either the square footage of the home or the number of vents. A typical air duct cleaning might cost anywhere from $300-$500. If you find you're being offered a really low price, you're going to want to question it."
There are a couple of ways to tell if your air ducts are dirty. One of the easiest ways to find out is to take the vent cover off, stick a camera phone down there and take a picture. Another sign is if the house is dusty a day or two after cleaning the house.
