The Paper Test

Step 1: Turn On the Dryer Safely

Number one, this is called the paper test and it’s one of the easiest ways to tell if your dryer vent is clogged. Simply turn on your dryer and be really careful when you open the door. There’s going to be a button that lets the dryer run and then it’s a safety feature that turns off when the door opens. So just hold your finger on that button and then turn it on air only so it doesn’t get hot.

Step 2: Use a Piece of Paper

Then take a piece of paper—any type of paper or just like white printer paper—and have the dryer running. Put that piece of paper up to where the lint tray is and you should be getting a nice snap. The paper should be snapping right there and it should be very strong.

Step 3: Check for Suction Problems

If you’re not getting any type of suction when you put the paper there, then it could mean that your dryer vent is clogged.

Step 4: Try It with a Top Lint Tray

Also, you could do this if your lint tray is on the top. It’s a little bit easier—just take the lint tray out and then hold the paper there on the top of the dryer and it should be snapping in, trying to get sucked through that duct.

When Airflow Seems Fine but Drying Still Fails

Now, if you are getting good air flow and the paper is snapping but your dryer is still not working well, this could mean that there’s other problems.
Number one is it could be disconnected from the wall, so all the lint and dust could be just blowing behind the dryer. We see this a lot of times when there’s like a countertop or like built-in cabinets around the dryer and you can’t see behind there after you attach it.
Also, if there’s a disconnection in the attic—a lot of times in the attic the vents will start to deteriorate due to the humidity and the heat. It can be disconnected and all the dust and lint could be blowing into the hot attic and then this will cause your clothes not to dry as well as they should.
So, the paper test isn’t a sure thing, but it just lets you know if there’s air flow or not.

Checking the Outside Temperature

Another thing you could do to test if your dryer is clogged is check the outside temperature of the dryer. When the dryer is running, the outside temperature should be under 100°, about like 80 to 90°.
If it’s really hot to the touch, or if you have a temperature reader and you’re getting like 100° or hotter than that—or if it’s so hot that you could crack an egg and fry an egg on it—then your vent is probably clogged.

Inspecting the Vent Exit

Another thing you could do is actually go out to the exit of the vent. This will either be on the side of the house, which is easier because you don’t have to climb on the roof, or it could be on the roof.
If it is on the roof, please hire a professional, someone trained to go on roofs, because it could be dangerous. Then go up there and if you have an airflow meter you could hold it next to it to see if you’re getting air flow. But if not, you could just put your hand there and it should be blowing pretty hard.
If it’s not blowing hard or not blowing at all, then you need to have your vent checked. Also, it could be caused by the inside of the dryer being clogged.

Ways to Inspect Your Dryer Vent Exit

  • Check the vent exit location
    Go out to the exit of the vent. It will either be on the side of the house (easier to access) or on the roof.
  • Hire a professional if it’s on the roof
    If the vent exit is on the roof, do not attempt it yourself. Please hire a professional trained to go on roofs, since it can be dangerous.
  • Use an airflow meter
    If you have an airflow meter, hold it next to the vent exit to measure whether you’re getting proper airflow.
  • Do a hand check
    If you don’t have an airflow meter, place your hand near the vent exit. It should be blowing air pretty hard.
  • Identify weak or no airflow
    If it’s not blowing hard—or not blowing at all—then your vent likely needs to be checked.
  • Consider an internal blockage
    Weak airflow could also mean the inside of the dryer itself is clogged, not just the vent.

Final Tip

Most homes: every 12 months.
Heavy use, big family, pets, long/roof vents: every 6 months.
After any “warning signs” (slow drying, hot dryer, burning smell), schedule cleaning sooner. Book professional dryer vent cleaning in Atlanta with our team.

  • Clothes take 2+ cycles to dry
  • Dryer or laundry room is unusually hot or humid
  • Burning or musty smells
  • Lint around the vent cover/flap not opening fully
  • Dryer auto-shuts off or feels very hot to the touch

Try the paper test: run the dryer on air-only, hold the door switch, and place a sheet of paper over the lint screen opening. Strong suction = good airflow. Weak/no suction = likely blockage.
Also check airflow at the exterior vent; the flap should open and blow strongly.

  • Visual inspection of the vent path and transition hose
  • Mechanical brushing and high-powered vacuum extraction from dryer to termination
  • Clearing the exterior hood/flap and obstructions (lint, nesting)
  • Re-seating connections and airflow check at the end
  • Recommendations if repairs or upgrades are needed
  • For thorough, start-to-finish service, book our dryer vent cleaning service.

Price varies by vent length, number of turns, roof vs. side-wall exit, and obstructions (nests, severe blockages).

  • You can maintain the lint screen and gently vacuum the transition hose, but full vent cleaning usually needs pro-grade brushes, vacuums, and roof-safe tools.
  • DIY often misses deep lint, elbows, and roof hoods—leaving risk behind.
  • Best: rigid or semi-rigid metal duct for in-wall/attic runs.
  • Short UL-2158A–listed transition duct behind the dryer.
  • Avoid white vinyl or plastic ducting.
  • Many codes and manufacturers allow up to 35 ft equivalent length, minus reductions for elbows (often 5 ft per 90° bend, 2.5 ft per 45°).
  • Check your dryer’s manual for exact limits; longer runs may require a booster fan.
  • Lint trap: catches some lint; clean before/after each load.
  • Vent: carries moisture and lint outdoors; needs periodic professional cleaning to remove buildup you can’t reach from the lint screen.

Yes. We coordinate access with property managers/HOAs and can schedule multiple units efficiently.
