The National Fire Protection Association (NFPA) recommends cleaning dryer vents at least once per year. But depending on your household size, dryer usage, and vent configuration, you may need cleaning more frequently. Here's how to assess your specific situation.

Factors That Increase Cleaning Frequency

• Large household (4+ people) with heavy laundry loads
• Pets that shed — pet hair dramatically increases lint accumulation
• Long dryer vent runs (over 25 feet) or multiple elbows
• Flexible plastic or foil duct (vs. rigid metal) — lint accumulates faster
• Older dryer with less efficient lint trap
• Drying heavy items like towels, blankets, and jeans frequently

Signs Your Dryer Vent Needs Cleaning Now

• Clothes take more than one cycle to dry
• Dryer is hot to the touch during operation
• Laundry room is unusually warm or humid when dryer runs
• Burning smell during dryer operation
• Dryer shuts off before cycle completes (thermal overload protection)
• Visible lint around the dryer vent opening outside

The Fire Risk

Dryer fires are one of the leading causes of home fires in the United States — the NFPA reports nearly 14,000 dryer fires annually. Lint is highly flammable, and a clogged dryer vent creates the perfect conditions for ignition. In Colorado Springs, where many homes have longer vent runs due to construction styles, the risk is elevated.

Professional vs. DIY Cleaning

While homeowners can clean the accessible portion of the dryer vent with a brush kit, professional cleaning reaches the full length of the vent run, removes compacted lint that brushes can't dislodge, and inspects the vent for damage or improper installation. We recommend professional cleaning annually and DIY cleaning between professional visits.
