I'm in a bit of a tough spot as the HVAC in my apartment is broken and it could take months to fix. It's super hot outside—101 degrees F—and my portable AC unit is working, but it's struggling to keep the apartment cool, which is around 82 degrees. My bedroom feels a bit cooler, but I want to find ways to cool the living space. Has anyone had experience with swamp coolers or evaporative coolers in situations like this? I have high ceilings and large windows that don't open vertically. Another AC unit would be ideal, but I'd prefer to avoid the hassle of setting that up if I can. I noticed some swamp coolers online, but they don't have many reviews. I live in Maryland, where humidity can be an issue. Any advice?

Evaporative coolers aren't the best in humid climates like MD. I really think getting another portable AC is your best shot. If you can, look into 'over the sill' or similar window units that might fit your unusual window setup better. Those are often more efficient than standard units!
It really depends on the humidity levels. If you go for the simplest method of just blowing air through a wet cloth, you might end up with a more humid space, which isn't great. If you can find a model that has both interior and exterior functions, that could work better, but they tend to be pricier. Overall, an additional portable AC seems like a safer bet for your situation.
Yeah, evaporative coolers can work well in outdoor spaces, but if you're indoors, they could actually make it more humid, especially in a humid area like Maryland. I'd recommend going for that second AC unit instead—just make sure it’s a dual-hose model. Also, positioning a couple of fans near the ground can help distribute the air more effectively.

I appreciate the tips! I’d love to go for those types of window ACs, but my windows open like flipping a book, which makes things tricky. But I’ll definitely consider your advice for a portable AC!
