Exterior Dryer Vent 4" x 4" extension needed to get hot air away from house.
Elizabeth

We bought our house and the washer + dryer were always on the east side of the house.

Unfortunately the hot air from the dryer (outside goes up into the soffit) , because of it's location . Any idea of how to make an extension to fit on the outside of the house, hook up to a 4" diam ductwork of some sort to send the hot air away from the house?
Thank you,\\

Normally the hot air from the dryer is vented directly to the outside through the wall behind the dryer. The outlet is covered by a damper or a louvre hood.

If this can't be done you need to use sheet metal vents, with the minimum number of 90s. Flexible vents are acceptable but there is a limit on length.

Not knowing, seeing or inspecting your set up, it's almost impossible to tell you how to do your vent. Call a plumber.

It's hard to envision from your description, but the only way I could see a dryer vent going up the wall, then out of the soffit, is to use a 180 degree bend (goes from flowing skyward to pointing down at the ground), which is a big no-no. Dryer vents easily clog with lent and need to be cleaned periodically. You want the shortest, straightest and easiest-to-clean run possible. That's why they typically vent straight out of the wall to the outside. You will also find that most dryers are placed on exterior walls for this reason.

Fume or vapor vents may run upward, but particulate-carrying vents are best run level or downhill to reduce the chance of clogging which in this case can cause a hidden lint fire. That's code in one county I work in where there's also a limit of 40' run for a clothes dryer vent, and it must also be metal once it leaves the living space until it exits outside. Codes may differ where you are but it's good practice anyway.

I do not understand why you do not go straight out of the machine and then outside with a louver hood. going through the walls is only going to cause condensation inside the duct work.
