Air duct cleaning removes the dust, debris and build-up from the supply and return ducts that carry heated and cooled air around your home. Chimney Sweep Bros cleans air ducts across Orland Park and the Southwest Suburbs — but we are going to be straight with you about it, because this is a service with a bad reputation for a reason. Most homes do not need their ducts cleaned on a schedule. Some genuinely do. We will tell you honestly which one you are, and we are insured, local, and reachable seven days a week on (708) 432-3430.
The honest version first: does your home actually need it?
The U.S. Environmental Protection Agency’s position on duct cleaning is refreshingly blunt, and we agree with it: routine air duct cleaning has not been shown to prevent health problems, and dust in ducts largely stays put rather than circulating. In other words, cleaning ducts “just because” on a yearly schedule is not something the evidence supports — and any company telling you every home needs annual duct cleaning is selling, not advising.
The EPA does, however, say you should have your ducts cleaned when there is a specific, identifiable reason. Those reasons are real, and this is when to call us:
- Visible mold growth inside the ducts or on other parts of the HVAC system. This is the big one. If you can see it, or the house has a persistent musty smell that gets stronger when the system runs, get it looked at.
- Vermin infestation — evidence of rodents or insects living in the ductwork.
- Substantial debris — ducts clogged with dust and debris to the point that it is visibly discharging from the supply registers into the room.
- After a renovation or major construction, especially drywall work or sanding, which pushes fine construction dust deep into every duct.
- After the house has sat empty, or you have just bought it and have no idea what is in the system.
- A new HVAC system going into old ductwork, or persistent allergy symptoms that improve when you leave the house and that you have not been able to trace to anything else.
Air duct cleaning is not dryer vent cleaning
People conflate these constantly, so to be clear: they are two different jobs on two different systems. Dryer vent cleaning clears the single duct that carries hot, lint-laden air from your clothes dryer to the outside — that one is a genuine fire-safety job that most homes really do need on a schedule. Air duct cleaning is the HVAC supply and return ducts that heat and cool the house. If your dryer is taking two cycles, that is the dryer vent, not this. If you have visible mold in the HVAC system, that is this.
What we actually do
- Inspect first. We look in the ducts before quoting anything. If they are clean, we will tell you they are clean and you will not have paid us to clean nothing.
- Source removal, done properly. A truck-mounted or high-powered portable vacuum puts the whole duct system under negative pressure, and agitation tools (brushes and compressed-air whips) dislodge the debris from the duct walls so the vacuum carries it away — not into your rooms.
- Supply and return, plus the registers. A real job does the full system, not just the few vents you can see.
- Contain the dust. The whole point of negative pressure is that what comes off the duct walls goes into the machine, not your living room.
- Address the cause where there is one. If there is mold, cleaning without fixing the moisture source means it comes straight back. We will tell you that rather than take your money twice.
The scam warning, because you should hear it from us
Air duct cleaning has more than its share of bad operators, and the tell is almost always the price. The “$59 whole-house air duct special” you see advertised is bait: nobody cleans a full, multi-system duct network properly for that, and the number exists to get a technician in your door to upsell you on things you may not need. Our own pricing starts at $99, and we are clear about what that is — an entry price for a basic, single-system clean with easy access. A larger home, more than one system, or real contamination costs more, and we quote it honestly after we have looked, rather than advertising an impossibly low whole-house number and inventing the difference once we are on site. See our pricing.
What clean ducts will and will not do
So expectations are right: a proper duct cleaning removes accumulated dust and debris, and where there was mold or a nest, it removes a genuine problem. What it will not do is cure allergies on its own, or dramatically lower your energy bills, or need repeating every year. Anyone promising those things is overselling. We would rather do the job you actually need, once, and have you call us back for the chimney.
Frequently asked questions
Does my home really need its air ducts cleaned?
Probably not on a routine schedule. The EPA has found that routine duct cleaning has not been shown to prevent health problems, and household dust in ducts largely stays put. You genuinely need it when there is a specific cause — visible mold in the system, a vermin infestation, ducts so clogged that debris is blowing out of the registers, or after major construction. If none of those apply, we will tell you honestly that you do not need it.
What is the difference between air duct cleaning and dryer vent cleaning?
They are two different systems. Air duct cleaning is the HVAC supply and return ducts that heat and cool your house. Dryer vent cleaning is the single duct carrying hot, lint-laden air from your dryer to the outside — a fire-safety job that most homes do need on a schedule. If your clothes take two cycles to dry, that is the dryer vent, not your air ducts.
Why do I see air duct cleaning advertised for $59?
Because it is bait. Nobody cleans a whole, multi-system duct network properly for that price — the number exists to get a technician through your door to upsell. Industry sources agree that a whole-house clean advertised under about $300 is either done poorly or hides its real cost in add-ons. Our own pricing starts at $99, but that is honestly an entry price for a basic single-system clean; a full multi-system home is quoted after we inspect it.
Will cleaning my air ducts help my allergies?
Possibly, but do not count on it as a cure. If there is mold or a vermin problem in the ducts, removing it can genuinely help. But routine cleaning of an otherwise-normal system has not been shown to improve allergies on its own — the EPA is explicit about this. We would rather set that expectation honestly than take your money on a promise we cannot keep.
How do I know if I have mold in my air ducts?
The signs are a persistent musty smell that gets stronger when the HVAC system runs, and in some cases visible growth on registers or inside the ducts. Mold is the single most legitimate reason to clean ducts. But cleaning alone will not fix it — if there is mold, there is a moisture source feeding it, and that has to be addressed or it comes straight back.
Should I get my ducts cleaned after a renovation?
Yes, this is one of the clearest cases. Drywall work, sanding and demolition push enormous amounts of fine construction dust deep into the duct system, and it keeps recirculating for months afterward. Cleaning after major construction is one of the times it is genuinely worth doing.
How often should air ducts be cleaned?
There is no fixed schedule, and be wary of anyone who gives you one. Unlike a dryer vent, HVAC ducts should be cleaned when there is a reason — mold, vermin, heavy debris, post-construction — not on the calendar. For most homes that means rarely, if ever.
Do you do the whole system or just the vents I can see?
The whole system — supply ducts, return ducts and the registers. Cleaning only the few vents you can see is one of the corners bad operators cut. If the job is worth doing, it is worth doing on the full system, and we inspect first so you know what you are actually paying for.
