What Happens During a Professional Dryer Vent Cleaning Visit?
A lot of St. Augustine homeowners put off calling because they’re not sure what the visit actually involves. Here’s a straightforward walkthrough of what to expect from start to finish.
Before We Start
We ask a few quick questions first — how long the dryer takes to finish a load, when the vent was last cleaned (if ever), and whether you’ve noticed any specific issue like a burning smell or the dryer shutting off mid-cycle. This tells us what to look for once we’re at the vent itself.
The Before Airflow Check
We take a digital airflow reading at the exterior vent exit before touching anything. This gives us an actual number for how restricted the vent is, rather than guessing from how long your dryer has been taking to dry a load.
The Cleaning Itself
Rotary brush pass. A flexible rotary brush runs the full length of the duct, breaking up compacted lint along the walls of the vent — not just what’s reachable from either end.
High-power vacuum extraction. As the brush loosens material, a high-power vacuum pulls the loosened lint out of the line so it doesn’t just get pushed further down or left sitting in the duct.
Exterior hood and flapper check. We check that the flapper opens freely and closes fully, since a stuck-open or stuck-shut hood causes its own problems separate from lint buildup.
The After Airflow Check
Once the duct is clear, we take a second airflow reading at the same spot. Comparing the before-and-after numbers is the most honest way to show the vent is actually clear — not just to tell you it’s done, but to show you.
How Long It Takes
Most single-family home visits are a single, contained appointment. The exact time depends on the length of the duct run, how many bends it has, and how much buildup is inside — the kind of detail covered in our cost guide. If you’re weighing whether to attempt this yourself first, our DIY vs. professional guide walks through where a rod-and-brush kit falls short of a full rotary-brush-and-vacuum service.
