Air Duct Cleaning FAQ — Sioux Falls, SD

The cost depends on how many vents your home has, the size of the duct system, and how much buildup is in there. A small ranch house costs less than a larger two-story home with more linear footage of ductwork. Homes that have never been cleaned, or those with pets and recent renovation dust, take more time.

Most homes benefit from a cleaning every three to five years. Sioux Falls has dry summers with a lot of fine prairie dust that works its way into homes, so buildup happens faster than in wetter climates. If you have pets, smokers in the house, or you recently did any remodeling, move that timeline up. Homes built in the 1950s and 1960s in older neighborhoods like McKennan Park often haven't been touched in decades.

Visible dust blowing out of vents when the furnace kicks on is the clearest sign. You might also notice a musty or dusty smell when the system runs, or visible debris buildup around vent covers. If someone in your house has gotten more sneezy or congested indoors over the past year, dirty ducts are worth checking.

We start with a walkthrough to identify all supply and return vents and check the condition of the system. Then we connect a high-powered negative air vacuum to the main trunk line to create suction through the whole system. We work through each branch line with agitation tools to break loose buildup, and the vacuum pulls it out into a contained collection unit. The whole job typically takes two to four hours depending on system size.

It can help, but it's not a cure. Cleaning removes built-up dust, pet dander, and debris from inside the duct system so your HVAC isn't circulating that material every time it runs. For people with allergies or asthma, that's a real reduction in airborne irritants. It works best when combined with regular filter changes and keeping the system maintained.

Yes, as long as the contractor knows what they're doing. Older homes in areas like Whittier or the Cathedral District sometimes have flex duct connections or older metal sections that are more fragile than newer systems. A good contractor inspects the ductwork before running equipment through it and adjusts their approach if something looks weak or disconnected. If we find damaged sections, we'll tell you before we start.
