How Often Should You Clean Your Dryer Vent?
Short answer: once a year, for almost everybody. Here’s the longer answer, because “it depends” is only useful if you know what it depends on.
The Annual Standard
Most fire safety and appliance guidance points to once-a-year cleaning for a typical household.
Once a year is the standard most manufacturers and fire safety organizations recommend, and it’s what we tell most customers who ask us straight out. It’s frequent enough to stay ahead of a fire risk and keep your energy bills in check, without being so often that you’re paying for cleanings you don’t need.
When You Need It More Often
A few situations push that timeline shorter. A large household running multiple loads a day builds up lint faster than someone living alone. Pet owners deal with extra fiber and hair going through every wash-and-dry cycle. A long or multi-bend vent run gives lint more places to collect along the way. And here in St. Augustine, our humidity plays a role too — moist air makes lint pack down and mat together faster than it would in a drier climate, which is part of why we don’t recommend stretching much past twelve months even for a lighter-use household.
Short-term rental properties are their own category, often needing service twice a year given how constant the turnover and dryer use tend to be.
The Air Duct 3–5 Year Confusion Explained
If you’ve seen a “3 to 5 years” recommendation somewhere, that’s for HVAC air duct cleaning, not dryer vent cleaning — two completely different systems on two completely different schedules. Dryer vent cleaning is annual because it’s directly tied to fire risk from a specific appliance running heat through it constantly. HVAC ducts don’t carry that same heat-and-lint combination, so they can go much longer between cleanings. Mixing up the two timelines is one of the most common points of confusion we run into.
