Runnells is a small town in southeastern Polk County, with plenty of acreages and country roads around it. Homes out here run the furnace hard in winter and the air conditioning hard in summer. Top Notch Chimney Sweep & Services, a family owned and operated company serving Central Iowa since 2002, cleans air ducts as well as chimneys, so one call can cover both.
What Collects in Your Ductwork

Every time your system runs, it moves air through the ducts. Over months and years, dust, pet hair, construction leftovers and general household debris settle in the duct runs. On rural properties, field dust and pollen during planting and harvest add to it. Homes with dogs, cats, or a recent remodel tend to collect more.
Some of that debris just sits there. Some of it gets pushed back out through the registers. A cleaning removes the buildup so your system is moving air through clean ductwork.
How We Clean Ducts
Our air duct cleaning service starts with a look at your heating and cooling system. Then we set up a powerful HEPA vacuum system, which keeps the dust we loosen contained instead of letting it blow back into your house. Specialized brushes work through the ducts to break the debris free, and the vacuum pulls it out.
While we’re in there, we check for holes, disconnected sections or other defects in the ductwork and let you know what we find. Leaky ducts waste the air you’re paying to heat and cool.
Good times to consider a duct cleaning
- After a remodel or any project that made a lot of dust
- When you move into a home and don’t know its history
- If you see dust blowing from registers when the system kicks on
- If it’s simply been years and you can’t remember the last time
Dryer Vents on the Same Visit
Lint in a dryer vent is a fire risk and makes your dryer work harder. If you’re having ducts cleaned, it makes sense to have the dryer vent cleaned at the same time.
And the Chimney
Many Runnells homes have a fireplace or wood stove too. An annual chimney sweeping removes creosote and lets us check the system before winter.
Why Indoor Air Deserves Attention
The EPA has ranked indoor air quality as one of the top five environmental risks to public health. Most people don’t think of their home as the dusty place, but with windows closed for much of the Iowa winter and again during summer heat, the same air moves through the ducts over and over.
That matters most for anyone with allergies, asthma or other breathing problems. Dust and debris in the ductwork can be stirred up and carried into the rooms where your family spends its time. A thorough cleaning removes it at the source rather than just catching what comes out the vents.
Humidity and the Duct System
Iowa summers get humid. When moisture finds its way into the ductwork, it can combine with the dust already there and give mold a place to grow. A musty smell when the air conditioning kicks on is one sign to pay attention to.
During a cleaning we look for any sign of moisture problems in the system and let you know what we see. Finding the source of the moisture matters as much as cleaning out what’s already there.
Keeping Ducts Cleaner Between Visits
A few habits slow the buildup down:
- Change your furnace filter on the schedule the manufacturer recommends, and more often during heavy use or after dusty work.
- Keep registers and return grilles clear of furniture and rugs so air can move freely.
- Close off or cover registers during sanding, drywall work or other projects that throw dust in the air.
- Vacuum the register covers when you clean the room.
These won’t replace a professional cleaning, but they help the ductwork stay cleaner for longer.
Country Homes, Country Chimneys
Out on the acreages around Runnells, it’s common to find a wood stove in a basement or shop, or an older brick chimney that’s been through many winters. Those deserve the same yearly attention as the ductwork. A chimney inspection with our camera shows us the condition of the liner, and it’s easy to schedule on the same day as a duct cleaning.
Booking both together means one visit, one set of drop cloths, and one crew that already knows your house.
Burning Wood the Clean Way
Many acreage owners near Runnells cut their own firewood, which is a great way to heat but comes with one rule: let it season. Freshly cut wood holds a lot of water, and burning it means a cool, smoky fire that coats the flue with creosote. Split it, stack it off the ground with the ends open to the air, and cover the top while leaving the sides open. Most wood needs at least a full season of drying before it burns well.
Burn hot fires with plenty of air rather than damping a stove down to smolder overnight. A smoldering stove is one of the fastest ways to build creosote, and creosote is what fuels a chimney fire.
One Thing Behind Several Risks
Carbon monoxide links all three of the systems we service. A blocked chimney flue, a clogged dryer vent on a gas dryer and a poorly venting gas fireplace can each push it back into the house. It has no color and no smell. Every home with fuel-burning appliances should have working carbon monoxide detectors, tested regularly, and a clear path to the outside for every vent and flue. Keeping the ducts, dryer vent and chimney clean is part of keeping a Runnells home safe through a long winter with the windows shut.
Detectors belong on every level of the house and outside each sleeping area. Replace them on the schedule printed on the unit, since the sensors wear out with age even when the batteries are fresh. If one sounds, get everyone outside first and call for help from there.
Certified People
Duct work is done by the same people who sweep chimneys, and they carry certifications in air duct and dryer vent cleaning. On the chimney side we have a CSIA Certified Chimney Sweep and a Certified Chimney Professional. Tom Hunkele, who owns the company, is a former President of the National Chimney Sweep Guild.
Duct cleaning isn’t something most homes need every year. How often depends on how much dust your household makes, whether you have pets, and what’s been going on in the house. We’ll give you a straight answer about whether your system needs it now or can wait.
We also serve Pleasant Hill and Carlisle.
