Dryer Vent Cleaning Cost Calculator

Dryer vent cleaning typically runs $80 to $200-plus per vent, with most standard residential jobs around $100 to $170 and a service-call minimum of about $80 to $100. The vent configuration is the biggest driver — a short, direct run is cheapest, a roof-terminated vent the most because of the harder, at-height access — followed by the lint buildup (a heavy years-of-clog job takes far more work than a lightly-maintained vent) and the access. It's a relatively affordable but genuinely important safety service.

Mostly fire safety. As a dryer runs, flammable lint builds up inside the vent, restricting airflow and making the dryer overheat — and clogged dryer vents are a leading cause of house fires each year. Cleaning removes that lint and cuts the risk sharply. It also restores airflow so clothes dry faster and the dryer uses less energy and lasts longer, and on gas dryers a clog can back carbon monoxide into the home. In short, it's cheap insurance against a real, preventable hazard, plus a nice efficiency bonus.

At least once a year for an average household. Heavy users (large families, daily loads) should do it every 6 months, and long or complex vents that trap more lint may need more frequent cleaning. Clean it right away regardless of schedule if you notice the warning signs. And separate from the vent, clean the lint trap after every load — that's basic maintenance, not a substitute for cleaning the duct run to the exterior.

The most common is clothes taking longer to dry or needing multiple cycles. Others: the dryer, clothes, or laundry room feel unusually hot at the end of a cycle; a burning or musty smell; more lint than usual around the dryer or at the exterior vent; the exterior flap not opening when the dryer runs; the dryer shutting off mid-cycle from overheating; or excess humidity in the room. A burning smell or overheating is urgent — stop using the dryer and get it cleaned. If it's been over a year, buildup is likely even without obvious signs.

They clean different systems. Dryer vent cleaning clears the single exhaust duct running from your clothes dryer to the outside — a fire-safety and efficiency service, usually $80 to $200. Air duct cleaning cleans your HVAC system's whole network of supply and return ducts for indoor air quality, a larger job at $300 to $700-plus. Different ductwork, different purpose, different frequency: dryer vents get cleaned at least yearly as a safety priority, HVAC ducts far less often. Make sure you're booking the one you actually need.

You can do basic maintenance with a DIY kit — flexible brush rods that attach to a drill, plus a vacuum. Unplug the dryer (shut off the gas on gas models), disconnect it from the vent, clean behind it and the transition hose, brush out the duct from both ends, and clean the exterior flap. That handles a short, accessible vent and helps between professional cleanings. But long or complex runs, roof-terminated vents, and heavy clogs need a pro's powerful equipment and reach — and roof work is unsafe to DIY. A good approach: DIY maintenance plus a periodic professional deep clean.

It happens often, especially where the exterior cover is missing or stuck open — the warm, sheltered opening attracts birds and small animals. A nest blocks airflow just like a lint clog (worse, since the nesting material is flammable) and the pests can damage the duct. It needs to be removed and the vent cleared, which a pro can do as part of the cleaning (the calculator has a bird-nest/pest-removal add-on). Live animals may need humane removal, and active nests can be legally protected in some areas. Preventing it comes down to a proper pest-resistant vent cover.

Sometimes the technician finds a problem worth fixing while they're there. A cracked, stuck, or missing exterior vent cap (~$70) lets pests in and won't seal — replacing it protects the vent and improves airflow. The flexible transition hose behind the dryer (~$60) can crush, kink, or use flammable foil that should be swapped for rigid or semi-rigid metal per code. If your ducting is improperly routed or too long, rerouting/reconnecting it (~$150) fixes airflow at the source. These are optional add-ons that come up when the vent has underlying issues, not just lint.

A camera inspection (~$50) sends a scope down the duct to confirm it's fully clear and spot damage, crushed sections, or hidden nests — useful for a long or complex run, or when you want proof the job's done. Sanitizing or deodorizing (~$40) treats the vent to knock out musty or mildew odors that can develop in a damp or long-neglected duct. Neither is essential on a routine clean, but the inspection is reassuring on a problem vent and sanitizing helps if you've noticed a smell. Both are offered as add-ons so you can include them when they fit.

A standard, accessible residential vent is usually 30 to 60 minutes — disconnect the dryer, clean behind it and the transition hose, run brushes and a vacuum through the full duct to the exterior, clean the flap, reconnect, and test airflow. Longer or complex runs, roof-terminated vents needing ladder or roof access, and heavy clogs or nests take 1 to 2-plus hours. Multiple vents add time, as do add-ons like a camera inspection or a vent-cap replacement. Most single-vent jobs are a quick, one-visit service.
