Air Duct Cleaning in Independence, MO

Yes, and they usually need it more than anything newer. A lot of the pre-1940 homes around the historic square and the Truman-era blocks were converted from gravity heat, so you've got oversized sheet metal trunks running the basement ceiling that were sized for warm air drifting up, not for a blower pushing it. Air moves slowly through pipe that big, so dust settles instead of staying airborne. We cut and patch access points in the trunk where there isn't one already, brush and vacuum the length of it, then handle the branch runs off it. The old joints are often taped or sealed by hand over the decades, so we work around what's there rather than pulling it apart.

In Independence the problem is usually wetter than it is dusty. Summer dew points here are high, and an unfinished basement holds that moisture against cold metal. The two places it shows up are the evaporator coil and the return plenum right above the furnace. Condensation sits there, picks up the fine dust coming off a limestone and clay soil basement floor, and you get growth that no amount of brushing the supply runs will fix. If that's what's happening, we tell you the ducts aren't the whole story and look at the coil and plenum. Cleaning around a wet plenum without addressing the humidity buys you a few weeks.
