What would you do in this awkward landlording situation?

[Gwen Fyfe]

I rented out one of my properties a couple months ago. I vaguely remember that I thought there was central air in this one because I had glanced at the thermostat and it had a "cool" option (yeah, they all start to blend together) and that I mentioned this on a couple of the tours.

I must have mentioned it when the people who became my tenants took the place, because I just got a text saying the central air isn't working. (It's very hot in Cleveland right now.) Thinking about it now, I don't think that house actually does have central air. I think it just has a thermostat with a "cool" option. D'oh.

Tenant's text says "we're paying for central air" which isn't really true, they're paying a pretty reasonable rent for the area. I also checked their lease and AC isn't listed as something I provide on it. But I don't want to be a jerk. And they're generally good tenants.

What would you do?
