(WDEF) There's no scientific proof that regular duct cleaning improves air quality, but some consumers say they experience fewer allergy symptoms after an air duct cleaning.
Adam Ketterman is a homeowner. He said, "I did feel a lot better physically right after the duct cleaning like within two to three days. I noticed it was like flipping a switch, so I was kind of excited about that."
Air duct cleaning is designed to remove air-borne dust and debris from components of HVAC systems, forced air systems, gravity heaters and other related systems.
Dave Adams owns an air duct cleaning company. He said, "So this is our negative air machine where the suction or the vacuum hose leads into this. When it's on, it fills up and all the debris that we get out of your ducts is collected right here."
There are a couple of ways to tell if your air ducts are dirty. Adams added, "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. They are going to be able to see down the duct. Another sign is if the house is dusty a day or two after cleaning the house."
Angie's List says you have to do your research when hiring to make sure you get a reputable contractor.
Angie Hicks of Angie's List said, "One of the more common things that we hear about with air duct cleaning comes down to pricing. 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."
