EDIT: I've attached a rough map of the situation. The laundry room is the little room in the middle. The red dot is where the dryer vents into the garage.
My house is weird. Built mid-1970s. Upper Midwest.
One of the weird/annoying things about my house is the fact that the clothes dryer vent opens up into the house's attached garage rather than venting outside. This is an electric dryer, so the vent is just hot wet air -- nothing like CO or anything.
Ideally, I'd like the dryer to vent to the outside and not turn my garage into a stagnant humid swamp every time I dry clothes (most days, actually, because I have many children). But the laundry room isn't situated in a way that makes outside venting easy. It's on the main level, right in the middle of the floorplan. No basement access, so I can't add ductwork through the floor. No usable ceiling access either.
What options do I have to make this mess annoying? Add venting to the garage somehow?
They're not without tradeoffs, but ventless dryers (aka heat pump dryers) have made a lot of strides the past few years. They tend to take longer than traditional dryers I believe, but use 30% less electricity overall, and don't need a vent. There's an $840 tax credit in the inflation reduction act that covers them, but as far as I can find it hasn't been rolled out yet.
I have a Miele washer/heat pump dryer combo. From my experience, the dryer is about the same as what I'm used to from a conventional dryer (~45 minutes), but the washer takes a lot longer. As I understand it, the washer does a more thorough spin cycle so the dryer has to do less work.
That said, I have been very happy with mine.
