Air Duct Cleaning in Pleasant Hill, MO

Frequently Asked Questions

Our crawlspace ducts are old and beat up. Is cleaning worth it, or should those runs just be replaced?

That's the first thing we look at before quoting anything. A lot of Pleasant Hill homes have duct runs sitting low in a crawlspace over bare or barely sealed ground, and after enough years of soil moisture the flex liner tears, the insulation sags wet, or a boot pulls loose at the floor register. Cleaning does nothing for any of that. If the inner liner is shredded or a run is holding damp, we'll tell you it needs replaced instead of cleaned. Where the ductwork is still intact and just loaded with dust, cleaning is the right call and it holds. We'd rather crawl it first and give you a straight answer than clean something that's failing.

Why do our supply registers smell musty, especially in the rooms over the crawlspace?

This is probably the most common complaint we hear in town. When duct runs pass through a crawlspace with exposed dirt, they pick up ground moisture and the stale air that sits down there. Any gap at a joint, a loose boot, or a torn section of flex lets that air get pulled into the supply side and pushed up through the floor registers. Cleaning the ducts removes the settled dust and debris that holds the odor, but if the crawlspace itself is damp and open to the dirt, the smell comes back. We'll point out where air is getting in and what the crawlspace is contributing so you're not paying to chase the same problem twice.

With the fields around here, how often should we actually have the ducts cleaned?

More often than a house in the middle of a subdivision in the suburbs. Row crop and hay ground on the edges of town kicks up field dust all season, harvest adds chaff, and ragweed runs heavy through late summer. If you run windows open in the fall or have a gravel drive, that load builds fast in the return side. For most homes here a cleaning every few years is reasonable, sooner if you're on acreage, have livestock nearby, or have someone in the house with allergies that flare in August and September. Changing filters more often between cleanings does a lot of the work for you.

What makes one Pleasant Hill house cost more than another?

Mostly layout and access, not square footage. The older frame homes near the historic core often had heating retrofitted into a house that wasn't built for ductwork, so runs are short, odd, and tucked into tight spots that take longer to reach. Acreage builds outside the natural-gas footprint tend to have long trunk runs and more registers to pull. A basement system with open joists is quicker than a low crawlspace where we're working flat on our backs. Homes with two systems, or a heat pump plus a propane backup, mean two sets of ducts. We walk the house and tell you what you're dealing with before we start.
