I live in an apartment. We are lucky that we have a washer/dryer in the unit, rather than having a shared coin-operated washer/dryer, but our dryer is so OLD and doesn't dry very well. I really think it's a large part of the reason our energy bill is $80-$90/month. Most loads (and not super-huge loads, either) take 2 or even 3 cycles to dry. We always empty the lint trap.
I've started hanging my work dress clothes back up after I come home in the evenings, to be worn a few more times before washing, as they aren't really dirty, but my BF's work clothes (he's a chef) get filthy, greasy, & sweaty, and need washing every wear.
I know our dryer has a white OLD vinyl hose (vent duct? Not sure of the term) that truly starts to crumble if you touch it. It's not even secured to anything - just pressed against a hole in the wall. I know that those old ones aren't considered very safe, and most people have the ones that look like tinfoil. (You can see how handy I am - NOT!) Is this something I could replace myself, and would it make a real difference in energy efficiency? Is there anything else I can do to this dryer?
