AC only above 75 degrees allowed at my Airbnb

I just booked a long stay at an airbnb in the US, but there is no cancelation option. Before I booked the house rules in the listing were pretty basic. After booking, I received a "house manual" in addition to the house rules I had already read before booking. The house manual says that the air conditioner must be kept above 75, which hardly seems like providing the amenity. It also includes using only specific name brand cleaning products/personal hygiene items that are much more expensive than what I usually buy, among other new rules. Shouldn't these kind of things been disclosed BEFORE booking? How do I prevent this in the future? I usually message the host a couple of basic questions before booking to make sure it's a good fit, but I'm not sure how to throw possible question darts to sus these things out without sounding like I'm a high maintenance weirdo.

Edits: I'm not saying 75 is always unreasonable (although it certainly can be in the humid environment we're staying in). I'm bothered that it wasn't disclosed before booking in the house rules. For those asking it is central air/refrigerated air, not a swamp cooler.

Other things that were disclosed after booking were only buying and using a particular tp brand that is about 3 times the price of Charmin and having to refill things we use like the salt and pepper when we check out even though they were included as amenities. And, no, they are not on a septic system.
