What's the frugal thing to do with a mildewy window A/C unit?
Of course, that means our window unit racks up work hours like nobody's business. We've had this particular window until for a few years now, and this year it really exploded with mildew. We tried cleaning it as best we could at the beginning of the summer, but we can't get the case off the exterior of the A/C, because one of the screws is fused with rust. By the end of the summer, it was gross with mildew all over again. We love going DIY whenever we can, but in this case it seems we're just not equipped to get the job done ourselves.
My question is: Are there any stores/services/common small businesses/etc. that would do a thorough disassembly, cleaning, and tune-up on a window unit like ours? Does anybody ever pay to maintain window units? Or are they one of those stupid appliances that are cheaper to replace outright than to maintain/repair? (Like mini fridges.)
