Key takeaways
- USFA estimates about 2,900 residential clothes dryer fires a year, causing about 5 deaths, 100 injuries and $35 million in property loss[1].
- Failure to clean was the leading factor contributing to ignition, at 34%, and dryer fires peak in fall and winter, highest in January[1]: a natural seasonal add-on.
- Sell it where it fits: on every dryer repair, on washer and dryer installs and in a fall safety campaign to past customers.
- Price by vent route and access, not a single flat number, and quote roof and long-run vents separately.
Why vent cleaning fits an appliance business
Appliance repair technicians already see the problem every week. A dryer that takes two cycles to dry a load, overheats or trips its thermal fuse is often not broken at all. The vent is restricted. Cleaning it fixes the complaint, protects the dryer and reduces fire risk. For a repair business, that makes dryer vent cleaning one of the most natural add-ons available: it uses skills and customers you already have, and it gives you a reason to call customers back every year.
It also suits the slow parts of the appliance calendar. Unlike holiday oven calls or summer refrigerator calls, vent cleaning can be scheduled, routed and sold in advance.
What the fire data says
The US Fire Administration's study of clothes dryer fires in residential buildings estimated about 2,900 such fires reported to fire departments each year, causing an estimated 5 deaths, 100 injuries and $35 million in property loss[1]. Failure to clean, at 34%, was the leading factor contributing to ignition, and dust, fiber and lint, at 28%, and clothing not on a person, at 27%, were by far the leading items first ignited[1].
The report explains the mechanism: lint is highly combustible, it builds up in the dryer and the vent, and accumulated lint reduces airflow. Vents can also be blocked by the nests of small birds or other animals, or by damage to the venting itself, so the dryer cannot exhaust properly[1]. Dryer fires are part of a larger picture: there were an estimated 344,600 residential building fires in the US in 2023[2].
The seasonal angle
USFA found that clothes dryer fire incidence in residential buildings was higher in the fall and winter months, peaking in January at 11%[1]. That gives you a clear marketing window. A campaign in September and October reaches customers before the peak, and it fills the weeks between the end of summer refrigerator calls and the start of the holiday oven rush.
- September: email and mail offers to past dryer repair and install customers.
- October: phone follow-up with customers who own gas dryers or long vent runs.
- November and December: offer cleaning on every dryer repair ticket and holiday move-in visit.
- January to March: book remaining requests on slower days, and target landlords and property managers before spring turnovers.
Equipment and training
Buy a proper kit
Rotary brush system with flexible rods long enough for your longest typical run, a high-power vacuum, transition duct and clamps, foil tape rated for ducts, and replacement exterior hoods.
Add inspection tools
A small inspection camera to see inside the vent and an airflow or pressure gauge to show the before-and-after difference to the customer.
Train for the route
Teach technicians to trace the full vent path, find concealed joints and recognize crushed or disconnected sections behind walls and in attics.
Set roof and ladder rules
Decide which roof vents you will service, require fall protection and a second person where needed, and refer jobs you cannot reach safely.
Document every job
Photos of the lint removed, the vent condition, the exterior hood and the transition duct, plus airflow readings if you take them.
What a good visit includes
- Inspect the lint trap, the trap housing and the area behind and under the dryer.
- Disconnect and inspect the transition duct; replace plastic or foil-type ducts with materials the dryer manufacturer allows.
- Clean the full vent run from inside and outside, and vacuum the dryer's internal lint path where accessible.
- Clear and check the exterior hood or roof cap, making sure the damper opens freely and is not screened in a way that traps lint.
- Reconnect, seal joints and run the dryer to confirm airflow at the exterior.
- Show the customer what was removed and leave a short report with photos and any recommended repairs.
Never leave a vent that is crushed, disconnected inside a wall or venting into an attic or crawl space without telling the customer in writing. These are safety findings, not upsells.
Pricing structure
Vent jobs vary more than they look. A short, straight run through an exterior wall is quick. A long run with several bends, a roof termination or an unreachable section takes much longer. Build a price structure that reflects that, and quote before you start.
| Component | How to price it | Notes |
|---|---|---|
| Standard cleaning | Base price for a ground-level vent up to your standard length | Covers most single-family homes |
| Long or complex runs | Add-on per extra length or bend, or a higher tier | Confirm on arrival before starting |
| Roof or second-story terminations | Separate tier for ladder or roof access | Include safety equipment and a second person |
| Repairs and parts | Priced separately: transition duct, hood, damper, duct sections | Show the damaged part to the customer |
| Add-on during repair | Reduced price when combined with a dryer repair visit | No extra trip cost |
| Multi-unit and property managers | Per-unit pricing with a minimum | Schedule by building |
Use your real costs. Labor, vehicle time and equipment wear should be covered by the base price, with complex jobs carrying their own margin. Appliance repair businesses are small, 79.5% of establishments have fewer than five employees[3], so a clear price list that the office can quote without the owner saves real time.
Cross-selling without pressure
The best moment to offer vent cleaning is when the customer can see the reason. Train technicians to check the vent on every dryer repair and to show what they find.
Technician script: "Your dryer is working again. While I was here, I checked the vent and it is about half blocked with lint, which is why loads were taking so long. I can clean it today while I am here for less than a separate visit. Would you like me to do that?"
- On dryer installs: include a vent check and offer cleaning if the existing vent is old or long.
- On washer repairs: mention the dryer vent if the units are stacked or in a closet with poor access.
- On move-ins: new homeowners often do not know when the vent was last cleaned.
- For gas dryer owners: combine vent cleaning with a check of the gas connection and venting.
Appliance installations are common: in 2025, 22% of surveyed US homeowners installed a new appliance[4]. Every dryer install is a chance to start an annual vent cleaning reminder.
Gas dryers and multi-unit buildings
Gas dryers add a second reason to keep vents clear: a blocked vent can push combustion gases back into the home. Each year more than 400 Americans die from unintentional carbon monoxide poisoning not linked to fires, and more than 100,000 visit an emergency department[5]. On gas dryer jobs, check the gas connector and shut-off, make sure the vent is complete and sealed, and recommend a working carbon monoxide alarm in the home. If you smell gas or find signs of spillage, stop and follow your gas safety procedure.
Apartment buildings, condos and townhomes are a separate market. Long shared vent runs, roof terminations and units with no record of cleaning are common. Property managers value a written schedule, a per-unit report and photos they can file. Quote these jobs by building, schedule them with the manager's notice requirements in mind, and confirm roof access and safety arrangements before the day.
Example: a fall vent campaign
Example (fictional): a three-technician appliance repair shop pulls every customer with a dryer repair or install in the past four years. In late September it sends a short email explaining that dryer fires peak in winter and offering vent cleaning on set days in each part of town. In October the office calls customers with roof vents or long runs, who are most likely to need help. Each booked visit is routed by zone, and technicians photograph every vent. At the end of the season, the owner reviews jobs per day, repairs found and the share of customers who agreed to an annual reminder.
Making it annual
Vent cleaning works best as a recurring service. At the end of each visit, ask the customer whether they want a reminder next fall and record the answer. Households with heavy laundry use, pets, long vent runs or roof terminations may need more frequent cleaning; say so when it applies. Combine the reminder with other seasonal checks you offer, so the customer hears from you once with a useful message rather than several times. For other seasonal appliance work, see summer appliance calls and the holiday appliance repair rush.
Frequently asked questions
How often should a dryer vent be cleaned?
Many homes need it about once a year. Heavy use, pets, long vent runs and roof terminations can mean more often. Signs include long drying times and a hot dryer cabinet.
Why are dryer fires more common in winter?
USFA found that dryer fires in residential buildings were higher in the fall and winter months, peaking in January. Booking cleanings in early fall gets ahead of that peak.
Can an appliance repair company offer dryer vent cleaning?
Yes. It fits the skills and customers of an appliance business. Check local requirements for any vent replacement work and set clear rules for roof access.
What are the signs of a clogged dryer vent?
Clothes taking longer to dry, the dryer or laundry room getting very hot, a burning smell, lint around the door or exterior hood, and a hood damper that barely opens when the dryer runs.
