Because it was represented as a feature when someone decided to rent the place.
Pardon? It wasn’t on the lease, so it wasn’t.
For example, nothing requires an outlet or switch to work, as long as it’s safe, but we expect that to work. I doubt anything requires all burners on a stove to work, but it’s certainly expected. Nothing requires windows to open but it’s expected.
Actually, codes and legislations do! Your entire comment is misguided yeesh. AC IS different since no codes, legislations, or the lease requires it. A stove is require by code, legislations, and lease, so if it doesn’t work, that’s an issue.
So you understand the very important distinction now….? Probably not, but do you?
