Heh, I never checked the humidity, as I loooooove me some humidity. 75 degrees and humid is glorious, in my opinion.
Hmmm? Don’t you just prop it in the window? What’s the extra installation?
MM, we recently (around April iirc) replaced an evaporative cooler with a one-hose room air conditioner.
We’re in Virginia, and it gets warm and humid here early on.
We have a pet chinchilla, and they are subject to strokes at temperatures of 80 degree F or higher. In Virginia, our indoor air temp was pegging 78+ in March. Chins also are near-desert animals and high humidity is not desirable, although I don’t know if it’s directly harmful.
We have chilled water central air in our condo, which works pretty well, but only after the chilled water supply is turned on. That happens at a specific time each year (negotiated between our condo board and the provider), and if it gets hot and humid before that time, bye-bye chinchilla, potentially.
The evap cooler labored mightily but did not seem to help much. I understand it works better in dry areas.
The room A/C unit was around $300 or $350 iirc (a pretty good price) from Hime Depot. The exhaust tube fits through a barrier you can put either horizontally or vertically in your window.
The first night we turned it on, it knocked the temp in the bird room down 8 degrees in 20 minutes. It’s plenty powerful enough for one room…sometimes I had to turn it off or turn the setting warmer to keep it from getting too cold.
It probably consumes a ton of electricity – sometimes the lights seem to dim when it cuts in – but we pay a flat fee to the condo association every month, so we don’t see any bill. 
We don’t feel guilty about it because we run it only to keep our animal alive.
Unfortunately I do not remember the brand and model. But some quick googling leads me to think it’s this one, or somethign very close:
You’ll need to look into square footage and getting the right BTU or cubic cooling capacity for your square footage, but the one we got (which I think is the one I linked to) works very well in a standard (15x 20 foot, I vaguely recall from measuring it years ago?) bedroom.
For our purposes, we are very pleased with this unit, and frankly surprised at the difference in effective power between it and the (admittedly cheaper) evaporative cooler.

This week I bought a Kenmore 10,000 BTU model with two tubes, no water tank.
Yes it’s pricey, but I have casement windows in my apartment, so I was going to be spending the same amount of money for a vertical unit, then I’d have to bolt it into place, into one room. Lame
The big advantage is that it really is portable. It’s a piece of cake to wheel it into my daughter’s room, blast it in there for an hour before she goes to bed, then wheel it where needed for the rest of the evening.
The window blockers w/holes don’t really fit the windows in my apartment terribly well, but I’ll adjust that over the next few days. I’ll probably end up cutting something to measure out of some corrugated cardboard I have lying around.
