I just got an old car and need to keep my garage dry and well-ventilated.

Right now my biggest problem is that I have about 3 feet of 4-inch dryer exhaust hose going from my laundry room to a hole that feeds the exhaust right into the garage. It blows a lot of warm and humid air into the garage.

  1. Should I do the work to redirect this hose to the outdoors?
  2. Can I avoid that by getting another length of hose, connecting it to the exhaust hole, and letting the output end sit under the garage door?
  3. Any other ideas?

    If by well ventilated you have lots of air coming in and going out, then maybe nothing needs to change. Adding extra pipe/hose and venting dryer outside is cheap also, as long as you don't need excessive length, around 10 or 15 feet be okay if only using 3 feet now. Check for change in dryer times.

My neighbor had a handy man run about 20 feet of 4" PVC sch 40 pipe and 3 elbows through his garage and exit through the wall. The dryer runs fine with no change in the dryers performance.

    That will be fun in a lint fire. Not that many other commonly used dryer vents (the accordion hose junk, foil or not) won't also be. I stick to solid metal for dryer ducts.
