The Short Answer
Once a year for a typical household; every six months for daily-laundry families, homes with shedding pets, or long and roof-vented duct runs; quarterly for laundromats and multi-unit setups. The best real-world gauge, though, is drying time — the moment loads start needing longer, the vent is due regardless of the calendar.
The Baseline: Once a Year
For most homes, an annual dryer vent cleaning is the right rhythm. Over a year, even careful households accumulate enough lint in the duct to noticeably slow drying and start creeping toward a fire risk — but not so fast that more frequent cleaning is usually necessary. Think of it like a furnace filter or a smoke-detector battery: a small, once-a-year habit that quietly prevents a large, expensive problem.
Your Schedule by Household
| Your Household | Clean It | Why |
|---|---|---|
| Couple or small household | Once a year | A few loads a week keeps lint accumulation modest |
| Busy family (daily loads) | Every 6 months | Volume doubles the lint; drying time is your gauge |
| Home with shedding pets | Every 6 months | Pet hair packs the duct far faster than fabric lint alone |
| Long or roof-vented run | Every 6–12 months | More distance and bends trap more lint per load |
| Laundromat / multi-unit | Quarterly or more | Constant use and high fire exposure — treat as commercial |
The Best Real-World Gauge
Calendars are a starting point; your dryer is the real authority. The moment a normal load stops drying in a single cycle, the vent is telling you it is due — earlier than a year if your usage is heavy, later if it is light. Pair that with a quick monthly glance: is the outside vent flap opening firmly when the dryer runs, and is the laundry room staying cool? Those two checks catch a building clog long before it becomes the warning signs in our clogged-vent guide.
“Don't set a reminder for the vent — let the laundry do it. When a towel needs two rounds, that's the alarm.”

DIY or Professional?
A short, straight duct is a fair DIY job with a rotary brush kit — the full method is in our how-to-clean-a-dryer-vent guide. Bring in a professional when the run is long or winding, terminates on the roof, refuses to clear with a brush, or has shown any warning sign. Our dryer vent cleaning service in Sherwood Park clears the full run with powered equipment and verifies airflow — and what that costs is broken down in the cost guide.
Frequency Questions, Answered
How often should a dryer vent be cleaned?
Once a year is the baseline for a typical household. Step it up to every six months if you run a load most days, have shedding pets, or your dryer vents through a long or roof-terminated duct. The single best real-world gauge is drying time — when loads start needing longer, the vent is telling you it is due, whatever the calendar says.
What happens if you never clean your dryer vent?
Lint keeps accumulating until airflow is choked. First drying slows and your power bill climbs; then the dryer overheats, aging its heating parts early and tripping its safety shutoff; and eventually the trapped lint beside the heat source becomes a genuine fire hazard. Every one of those is prevented by a routine annual cleaning.
Can I clean the dryer vent myself, or should I hire someone?
A short, straight duct is a reasonable DIY job with a rotary vent brush — our how-to guide walks through it. Hire a professional when the run is long, has multiple bends, or terminates on the roof, when a hand brush cannot reach the blockage, or when you have seen warning signs like a burning smell. Powered equipment clears what a brush cannot, and airflow gets verified afterward.
