This happened to my parents in the 90s in Florida. They did a consultation with a lawyer and he told them to stop paying rent. So they did. Saved the money and used it to make a downpayment on their first house. I don’t know if it still applies but it’s probably worth a look.

True story?

I don’t know about other places, but in the U.S., generally if your house is fucked to the extent of being kindof uninhabitable (and I’d think no AC would qualify – though maybe depending on local climate, that might not so much be seen as the case?), your landlord would have to get it fixed or pay for a hotel stay until it was fixed.

Or maybe in your case, it’s more of a condo situation where you don’t have a landlord.

Or maybe I’m off base thinking a lack of AC in July would qualify as sufficiently uninhabitable to require your landlord to be responsible for an alternate dwelling.
