00:00Did you know a guy will come to your house, snake a spinning brush through your dryer vent,
00:05and hand you a bill between $100 and $3 and $186, $200 and up, if the pipe goes through a
00:11roof?
00:12Meanwhile, a 30-inch lint brush is $8 or $9, and a 12-30 foot kit that chucks into the
00:18drill you
00:18already own is $31 to $40 at the hardware store. Most of that $200 visit is lint you can pull
00:24yourself in an afternoon. Here's the part that should bother you. You already clean the little
00:29screen in the door. That screen is a strainer, not the pipe. The hot, wet air still has to crawl
00:34through a 4-inch tube, around a crushed foil accordion behind the machine, and not a flap
00:39on the siding. Lint packs that tube like felt. Clothes take two cycles. The laundry room gets
00:45weirdly hot, and the National Fire Protection Association's own dryer fire numbers keep
00:49pointing at the same first fuel, dust, fiber, lint, and a failure to clean. I do this once a year
00:55now.
00:56I'm not writing a $150 check for a pipe I can reach with a brush. By the end of this,
01:01you will know the 30-second flap test, the housing under the screen that the screen never gets,
01:06how to pull the crushed hose and actually brush the wall pipe, the cheap kit versus the leaf blower
01:11trick when the foil accordion is the real problem, and the one setup where you should still pay the
01:16$200. I left the kits, the government how-to, and the fire numbers in the description if you want
01:22the labels later. Right now, I'm walking you through it like we are in the laundry room.
01:26Here's what it does, in normal language. Your dryer is a hair dryer in a box. It blows hot air
01:31through wet clothes, and that air has to leave the house. If the exit is stuffed, the air sits there,
01:36the drum stays wet. The thermostat keeps calling for more heat, and you run a second cycle you did
01:41not need. A clean 4-inch pipe is a chimney. A dirty one is a sock. The brush does not
01:47magic anything.
01:48It rakes the felt off the wall so the chimney works again. Here's the recipe. First, the free test,
01:54and you do this before you buy a brush. Walk outside, find the dryer flap on the siding, start a
02:00load,
02:00or just turn the dryer on empty for a minute. That flap should kick open, and you should feel a
02:05firm
02:05push of warm air. If it barely twitches, if you see lint hanging like a beard, or if it is
02:11a screened vent cap
02:12packed into a gray pancake, the pipe is sick. A screen on a dryer cap is a lint trap in
02:17the worst possible
02:18place. Pull the screen if you can. Single flap or the louvers. No mesh. Second, unplug the dryer. Gas line
02:25stays put. You are not disconnecting gas. Pull the machine forward. If it is heavy, a moving blanket
02:31under the feet saves the vinyl. On the back is a hose, usually a shiny crushed accordion clamp to a
02:374-inch
02:37stub. Loosen the clamp with a screwdriver. Pull the hose off. Look inside. If it is a gray felt sock,
02:44that is your $200 visit sitting in your hand. Third, the $8 brush. This is the one people skip
02:50because the screen looked clean. Pop the lint screen out. Shine a light down that slot. There's a whole
02:56cavity under there. The screen never scrapes. A long, skinny lint trap brush. Walmart has them
03:01around $8.99. Goes down that slot. Twist, pull, and you will bring up a gray mouse you did not
03:07know you
03:07owned. Vacuum the slot with the hose. That cavity is why a clean screen still cooks a load for 70
03:14minutes. Fourth, the wall pipe. This is the actual vent. From the hole in the wall, feed a dryer vent
03:21brush kit. Home Depot's ever-built drill-powered kit is about $31 with a 4-inch head and snap-on
03:28rods.
03:28The 12-foot extendable one is the short-run kit. Hole at me's 30-foot Amazon kit is about $40
03:34if your pipe
03:34takes a tour through the joists. Chuck it in a drill on low. Clockwise in, clockwise out. Add a rod
03:40as
03:40you go. Do not floor the trigger and corkscrew a hole in a vinyl duct. Have a shop vac running
03:45at
03:46the wall hole so the felt comes towards you instead of deeper into the house. If you can reach the
03:50outside cap, pull the cap and brush from that end too. Two directions beat one heroic shove. Fifth, the
03:57proof. Reattach a smooth pipe. We will get to that. Clamp it. Plug back in. Run the dryer five minutes.
04:03Go outside. The flap should jump. Inside, the cabinet should not feel like a space heater.
04:09Next. Load. Time it. If you are at 70 minutes and you land near 40, that second cycle is gone.
04:16An electric dryer is a couple of kilowatt hours a load. At about 45 cents a run. A bonus cycle,
04:22every wash day is real money by December. The brush paid for itself and the extra electricity you stop
04:26buying. If this is already useful, subscribe. It is free. Members get the longer tests I keep off the main
04:32upload. I put the ever-built kit, the 30-foot brush, the PNNL steps, and the price ranges in the
04:38description so you can check the builds if you want to try this. The extras that save a failed
04:43Saturday are next. Now the $0 version if the kit is a Tuesday trip. A vacuum hose and a long
04:49sock or a
04:50dryer sheet rubber banded over the hose end will slurp the last two feet of crushed accordion. A leaf blower
04:55on
04:56lowest setting, aim from the dryer stub toward the outside cap, is the government how-to's other
05:01option. Lowest setting, cap off, someone watching the yard so you do not paint the siding with a lint
05:06cannon. It is messy. It works on a straight short run. It does not replace a brush on a pipe
05:12with two
05:12elbows. The accordion hose is the quiet villain. Foil crushed duct kinks the second you shove the dryer
05:18back. And every kink is a lint shelf. If that hose is gray and crispy, throw it out. Semi-rigid
05:24or rigid
05:25metal as short and as straight as you can make it, with the dryer sitting a few inches off the
05:29wall
05:30so you did not accordion a new clog on day one. That swap is $10 to $20, and it is
05:35the reason some
05:36people clean the vent every year and still cook loads. They cleaned a crushed straw. While the back
05:41is open, vacuum the floor under the dryer and the little intake slots low on the cabinet. Dust bunnies
05:47there get sucked in and join the felt. Wipe the moisture sensor bars inside the drum with a bit of
05:52rubbing alcohol on a cloth. The two metal strips. If those are filmed with fabric softener, the dryer
05:58thinks the clothes are wet forever and it will not shut off. That is a two minute extra. And it
06:03is why
06:03a clean vent still runs a ghost cycle. Outside, pop the cap once a season, even if the brush felt
06:08easy.
06:09Wasps, a bird nest, a plastic bag from the neighbor's can. The flap can look fine and still be a
06:15cork. If you
06:16find a nest or a pipe you cannot reach without a roof ladder, that is the $200 job. Roof vent,
06:2125 feet,
06:22in the wall. A 90 degree elbow you can feel but not see. Pay it. The brush is for the
06:28run you can
06:28actually enter. Pretending otherwise is how people snap a rod off in the joists and then really need
06:34the guy. Do this about once a year or the week the loads start taking a second round. Pet hair
06:40and
06:40towels pack a pipe faster than dress shirts. If you dry a house of hoodies every weekend, do not wait
06:46for
06:46a birthday. Keep the kit in the laundry closet. The $31 ever built is the one I would actually buy
06:51if I were
06:51starting from zero. 4 inch head, rods, drill chuck. The $8 wand is for the slot under the screen and
06:58you want both. The $40 30 footer is only if you measured a long run. Buying 30 feet for a
07:044 foot
07:04hop to the siding is how you store plastic you will never snap together. If this gets a gray mouse
07:10out
07:11of a pipe you forgot you had, send it to whoever just booked a $200 vent cleaned for a hose
07:16they could
07:16have pulled themselves. Take care and I will see you in the next one.
