Is Dryer Vent Cleaning Necessary? Experts Explain Why & How Often To Do It

Jul 24, 2025

Dryer vent maintenance is one of the most overlooked yet dangerous home tasks to neglect. You’re not alone if you’ve never considered it, but experts say basic upkeep prevents fire hazards and saves money.

A Fire Risk Hiding Behind the Wall

When it comes to household safety, few people think about the build-up hiding in their dryer vents. But according to the U.S. Fire Administration, lint-clogged vents are one of the leading causes of residential fires. The combo of high heat and trapped, flammable debris creates a hidden fire hazard—one that builds up quietly with every load of laundry.

Beyond the danger, dirty vents also affect how well your dryer performs. Blocked airflow forces the appliance to work harder, increasing energy bills and wearing out components faster.

So, Is It Really Necessary to Clean Your Dryer Vent?

Short answer: Yes. Experts recommend a professional cleaning at least once a year, but that can vary depending on your setup and usage.

You may need more frequent cleanings if:

  • Your dryer is in heavy use (multiple loads per day)
  • You notice signs like longer drying times, a burning smell, or hot surfaces
  • Your vent system has sharp turns or is longer than average (e.g. it exits through the roof)

What Happens If You Don't Clean It?

Beyond the obvious fire risk, here's what else can happen:

  • Appliance Wear: Overworked dryers are more likely to break down early.
  • Higher Energy Bills: Clogged vents slow down drying, forcing longer cycles.
  • Indoor Air Problems: Lint and moisture buildup can lead to mold, mildew, and allergens—especially if it recirculates back into your home.

Some professional technicians also offer air duct and HVAC vent cleaning, which may improve air quality by removing built-up dust and debris—though the health benefits of duct cleaning remain debated in scientific reviews. The U.S. Environmental Protection Agency recommends duct cleaning only if you see visible mold, pest infestations, or excessive dust interfering with airflow.

How Much Does It Cost to Clean Dryer Vents?

According to HomeAdvisor and Angi:

  • Roof vents: $150–$250
  • Standard cleaning: $103–$185
  • Second-floor vents: $110–$185
  • Ground-floor vents: $80–$150

Longer vents or ones with multiple bends typically cost more to clean. But considering the safety and energy savings, most homeowners find it's worth it.

Why More Homeowners Are Booking Professional Cleanings

The dryer vent cleaning industry is growing fast—and for good reason.

  • The global dryer vent cleaning services market is projected to hit $18.36 billion by 2025 (WK Information)
  • One report estimates $2.7 billion by 2033, growing at a 7% CAGR (DataIntelo)

Increased awareness, stricter building codes, and online booking tools are making it easier for homeowners to prioritize this once-forgotten task.

Companies specializing in this work often use HEPA-filtered equipment and certified technicians to ensure thorough, safe results—especially for properties with complex vent layouts or commercial-grade laundry systems.

How to Know You're Hiring a Pro

Reliable vent cleaning services will typically:

  • Provide flexible scheduling—even weekends
  • Offer transparent pricing and free estimates
  • Use specialized, professional-grade equipment
  • Be fully licensed, insured, and background-checked

New Jersey-based companies like Airflow Experts, for example, have seen growing demand from property managers and homeowners across all 21 counties. While every home is different, their technicians generally recommend annual dryer vent cleanings as a baseline for safety and efficiency.

Final Thought

Your dryer may be working harder than it needs to—and putting your home at risk in the process. If it's been over a year since your last dryer vent cleaning (or if you've never had one), now might be the time to act.
