About 2,900 home dryer fires get reported in the U.S. every year. Most people assume it's an electrical problem or a bad heating element. It's not. It's lint. Lint that built up in the vent line because nobody cleaned it out. I've been doing dryer vent cleaning in Orlando for years, and most homeowners don't think about their vent until the dryer takes two hours to dry a single load. Or until the fire department shows up.
A clogged vent also wastes energy. Your dryer has to run longer and hotter to push moist air through a restricted line. Higher electric bills, more wear on the machine. In Orlando's humidity, your dryer is already working harder than it would up north because clothes come out of the washer holding more moisture. Add a partially clogged vent to that and you've got a machine running at its limit every single load.
Warning signs your dryer vent is clogged
Longer dry times are usually the first thing people notice. A load that used to take 45 minutes now takes an hour and a half. The dryer can't push air out, so it just keeps running.
Other signs to watch for:
- The top of your dryer is hot to the touch during a cycle. Warm is normal. Hot enough to flinch is not.
- Your laundry room feels humid or warm while the dryer runs. If the vent is blocked, all that moisture goes right back into the room.
- You smell something musty or like hot lint. That smell is exactly what you think it is.
- The exterior vent flap barely opens when the dryer is on. Go outside and check while it's running. You should feel a strong push of warm air.
- You can't remember the last time you cleaned the vent. That means it's overdue.
In Orlando and Winter Park, I see a lot of homes where the dryer is on an interior wall and the vent runs 15 or 20 feet through the attic to reach the exterior. Those long runs through Florida attics are bad. The attic heat bakes the lint inside the duct and makes it harder over time. I've pulled sections of 4-inch aluminum duct out of attics packed with lint compacted like felt. Solid enough that you could hold the duct vertically and nothing would fall out.
How to clean your dryer vent yourself
If your vent run is short and mostly straight, you can handle this yourself. Check out our guide on DIY vs pro appliance repair. Here's how to do it properly.
First, unplug the dryer. If it's gas, turn off the gas supply valve too. Pull the dryer away from the wall so you can access the back. You'll see a 4-inch duct connector coming off the back of the dryer, attached to the vent line with a clamp or foil tape. Disconnect it.
Look inside the duct and inside the dryer's exhaust port. You'll probably see lint caked around the edges. Pull out what you can by hand, then grab a dryer vent brush kit. Long flexible rods with a brush head on the end, about $30 at any hardware store. Feed the brush in, spin it, pull it back. Repeat until it comes out clean.
Now go to the exterior vent opening outside your house. Remove the cover if you can and brush from that end too. Working from both ends is the only way to get the full length clean. I can't tell you how many times homeowners brush from the inside and think they're done, but there's a solid plug of lint sitting near the exterior opening.
While you have things apart, check the condition of the vent duct itself. If you're using white vinyl flex duct, replace it. That stuff is a fire hazard and isn't even up to code anymore. You want either rigid aluminum duct or, if you need flexibility, semi-rigid aluminum. The corrugated white plastic stuff traps lint in its ridges and can melt if the dryer overheats.
Reconnect everything, push the dryer back, and run it on air-dry for 10 minutes to blow out any loose lint you dislodged. Check the exterior vent while it runs. Strong airflow means you did it right.
When to call a pro for dryer vent cleaning
DIY works fine for short, simple runs. But if your vent goes more than 10 feet or has multiple elbows, a brush kit from the hardware store probably won't cut it. Every 90-degree turn adds the equivalent of about 5 feet of straight duct to the air resistance. A vent that goes up into the attic, turns twice, and runs 15 feet to the roof? You're not getting that clean with a hand brush. We use rotary brush systems powered by a drill that can reach 30 feet or more.
Condos and townhomes in Orlando and Kissimmee are another story. A lot of multi-story units have vents that run vertically through walls and come out on the roof. You can't reach those from inside, and you're not climbing a three-story building with a vent brush. The vents in these communities are often in terrible shape because they've never been cleaned since the building went up.
Also call someone if you pull your dryer out and find a bird nest in the vent. This happens more than you'd think. Birds love the warm exhaust air and they'll build right inside the exterior flap if it's broken or missing. I've found fully intact nests packed with lint and feathers blocking vents completely.
And if your dryer keeps tripping the thermal fuse, the vent is the first thing to check. A restricted vent causes the dryer to overheat, which blows the fuse. Replacing the fuse without fixing the vent just means it'll blow again in a few weeks. I replace thermal fuses all the time for people who've already gone through two or three because nobody looked at the vent. Check out our guide on why your dryer runs but won't heat.
How often should you clean your dryer vent in Orlando?
At minimum, once a year. If you have a large household doing laundry daily, every six months. Check out our guide on vacation rental appliance maintenance. If your vent run is long or goes through the attic, every six months regardless.
In between full cleanings, clean the lint screen before every single load. No exceptions. And once a month, wash the lint screen with soap and water. If you use dryer sheets, they leave an invisible film on the mesh that blocks airflow even when the screen looks clean. Try running water over yours right now. If the water pools on the mesh instead of passing straight through, that film is there and needs to be scrubbed off.
Florida's humidity makes lint stickier. Check out our guide on Florida appliance lifespan. It doesn't just sit loose in the duct like it would in a dry climate. It clings to the walls and layers up until it hardens. That's why annual cleaning in Orlando is the bare minimum, not some overly cautious recommendation.
