Dryer Maintenance
Lint, vents, and the small habits that keep your dryer safe and efficient.
How often should I clean my dryer vent?
Most homes should have their dryer vent professionally cleaned once a year. Households with long vent runs (over 25 feet), pets, or more than four loads of laundry per week should plan for every six months. The NFPA cites 'failure to clean' as the leading factor in U.S. dryer fires.

The top warning signs are: drying cycles longer than 45 minutes, clothes that come out hot but still damp, a hot laundry room or dryer exterior, a burning smell, visible lint around the outdoor vent hood, or the dryer shutting off mid-cycle. Any one of these warrants a professional inspection.

You can safely clean the lint trap, the first few feet of flex duct behind the dryer, and the outdoor vent hood yourself. Anything beyond that — long runs, roof vents, or rigid ducting through walls — should be done by a pro with a rotary brush system and a HEPA-filtered vacuum.

The vent cleaning is the same for both — lint is lint. But gas dryers carry a second risk: a blocked vent can back up combustion gases (including carbon monoxide) into your home. That makes timely vent cleaning especially critical for gas models, and a CO detector in the laundry room a must.

The International Residential Code limits dryer vent runs to 35 feet of 4-inch rigid metal duct, with a 5-foot deduction for every 90° elbow and a 2.5-foot deduction for every 45° elbow. If your measured run exceeds that, the dryer is working against code and cleaning alone won't fully solve the airflow problem — you may need a booster fan or a re-route.

The lint trap (or lint screen) is the small mesh filter inside the dryer itself — clean it every load. The vent is the four-inch duct that carries exhaust out of the house — it needs professional cleaning roughly once a year. Cleaning the trap does not clean the vent, and vice versa.
Read full answer →Do condenser (ventless) dryers need cleaning?
Yes — condenser and heat-pump dryers still have a lint filter and a secondary evaporator or condenser unit that both need regular cleaning. They don't have an exterior vent, so they don't need vent cleaning, but neglecting the internal condenser can reduce efficiency and shorten the lifespan of the unit significantly.

Yes — most dryers made after 2010 have thermal cut-off switches or airflow sensors that shut the unit down when internal temperature exceeds a safe limit, and a clogged vent is the #1 cause. It's a safety feature working correctly, but it's also a signal the vent needs immediate attention.

A sudden change in dryer noise is most often one of three things: drum rollers wearing down (a rhythmic thumping), a failing blower wheel (a high-pitched whine), or debris stuck in the lint-screen housing (scraping or rattling). None of these are vent-related, but all of them are worth investigating before they escalate.

With annual vent cleaning and routine lint-trap maintenance, a typical residential dryer lasts 10–13 years. Washers last 10–12 years for top-loaders and 7–10 years for front-loaders, though premium brands like Miele and Speed Queen routinely exceed 15 years. Neglecting vent cleaning can cut dryer lifespan roughly in half.
