How Often Should You Really Clean Your Dryer Vent?

Let’s be honest, your dryer vent probably isn’t something you think about often. It’s out of sight, out of mind… until your clothes start taking forever to dry, your energy bill creeps up, or worse, you smell something burning.

But here’s the thing: a clogged dryer vent is more than just an inconvenience. It can put your home at risk, cost you more money over time, and wear out your dryer way faster than it should.

In this post, we’ll explain exactly how often you should clean your dryer vent, why it matters for your safety and your wallet, and how to know when it’s time to take action.

First Things First: What Is a Dryer Vent, Anyway?

Your dryer vent is the part that pushes hot, moist air from your dryer to the outside of your home. It may not look like much, but when it gets clogged with lint, dust, or debris, that airflow gets blocked.


Let’s take a closer look at
how often you should actually be cleaning it and why doing it regularly makes a big difference (especially in climates like ours here in Southern New Hampshire).

Why Cleaning Your Dryer Vent Matters More Than You Think

More than just being annoying, lint buildup in your dryer vent can be dangerous. According to the NFPA, dryers are involved in 92% of the ~15,970 annual home fires linked to laundry machines, and failure to clean vents contributes to about one-third of those incidents. Besides this, the frequency with which you clean your dryer vent contributes to the following:


Prevents House Fires
Lint buildup is highly flammable, and blocked dryer vents are a leading cause of house fires. A simple yearly cleaning can significantly reduce the risk.

Improves Dryer Efficiency
A clogged vent forces your dryer to work harder, making clothes take longer to dry. This not only wastes time but also drives up your energy bills.

Extends Dryer Lifespan
Excess heat and strain from restricted airflow cause your dryer to wear out faster. Regular maintenance helps avoid premature breakdowns and costly repairs.

Keeps Moisture and Mold Out
When moist air can’t escape, it may seep back into your home—especially during cold New England winters—creating ideal conditions for mold and mildew.

So, How Often Should You Clean Your Dryer Vent?

If you’re wondering how often this really needs to be done, you’re not alone.


General Rule of Thumb

For most households, the minimum recommended schedule for dryer vent cleaning is once a year. That’s often enough to prevent dangerous lint buildup, keep your dryer running efficiently, and avoid unnecessary wear and tear.


But You Might Need to Clean It More Often If…

Some homes need more frequent cleanings—every 6 to 9 months—depending on how much laundry you do and a few other factors. If any of these sound like you, consider bumping up the frequency:


  • πŸ‘• You do laundry nearly every day (big family or shared laundry)
  • 🐾 You have pets that shed (pet hair adds to lint buildup)
  • 🧺 You regularly use fabric softener or dryer sheets (they leave residue)
  • πŸ”§ Your dryer is more than 8–10 years old
  • πŸŒ€ Your vent hose is long, has lots of turns, or exits through the roof

Honestly, we know it’s a lot to keep track of and most of these things aren’t visible without pulling your dryer out or climbing into the attic.


That’s why so many homeowners choose to call in a professional. It’s one less thing on your to-do list and you’ll know for sure that everything’s up to code, running safely, and not putting your home at risk. That’s the difference professional cleaning can make.

How to Tell If Your Dryer Vent Needs Cleaning

Not everyone can tell if it’s time to clean their dryer vent, and that’s okay. These common signs are your dryer’s way of trying to tell you something’s wrong:


  • Clothes take longer than usual to dry – This often means air isn’t flowing properly due to a clogged vent.

  • Dryer feels hot to the touch – Excess heat can signal restricted airflow, which makes your appliance work harder than it should.

  • A burning smell while drying – Lint is highly flammable; if you notice a burning odor, stop using the dryer and check the vent immediately.

  • Lint is building up around the vent opening – Visible lint outside the vent can be a warning sign of a deeper clog.

  • It’s been over a year since your last cleaning – Even without symptoms, regular cleanings are recommended at least annually to reduce fire risk.



πŸ’‘Pro tip:
  If you’ve noticed any of these, it’s time.

Can I Clean It Myself? Or Should I Call a Professional?

While it’s definitely possible to handle some aspects of dryer vent maintenance yourself, most homeowners don’t have access to the tools or visibility to do a complete job. When lint builds up deep inside walls or in hard-to-reach bends, even a thorough DIY attempt might miss critical areas without you noticing it until it is too late. 


Below is a quick look at what you can expect from a DIY clean versus calling in a professional:

DIY Cleaning Professional Cleaning
βœ… You can clean the lint trap after every load βœ… Experts clean the entire vent system, not just what you can see
βœ… You can use a vacuum or brush kit to remove some lint βœ… Specialized tools reach deep into long or curved ducts for a thorough clean
❌ Hard to clean behind or inside walls βœ… Pros handle tricky vent runs, bends, and rooftop exits with ease
❌ Easy to miss buildup that’s out of sight βœ… Trained eyes spot hidden problems like tears, clogs, or disconnected ducts
❌ No guarantee it’s fully cleared βœ… Peace of mind knowing it’s done right and your home is safe
πŸ’‘ Good for in-between maintenance πŸ’‘ Best for full annual cleanings and safety checks

FAQS

  • How do I know if my dryer vent needs cleaning?

    ​​If clothes take longer to dry or you notice a burning smell, it’s time.

    We recommend it once a year, especially in areas like Amherst, Brattleboro, or Pelham where seasonal use varies. More often if you do lots of laundry.


  • Is it safe to clean your dryer vent yourself?

    Basic maintenance like cleaning the lint trap is safe, but deeper cleaning can be tricky. Many prefer pros for peace of mind and to save themselves the trouble.


  • What happens if a dryer vent is not cleaned?

    Lint buildup restricts airflow, strains your dryer, and increases fire risk. This is something especially important to stay ahead of in wooded areas like Rindge or Hinsdale.

  • Is dryer vent cleaning worth it?

    Yes, it improves dryer performance, lowers energy bills, and reduces fire hazards. In New England towns with historic or well-established homes, like Walpole or Peterborough, it’s especially smart upkeep.

    Pricing depends on vent length, location, and how hard it is to access. Homes with rooftop exits or long duct runs may cost a bit more. The best way to provide an exact estimate is for us to assess your specific situation.
