Air conditioning in unoccupied STRs?

[Paul Sandhu]

There was a construction crew that rented 7 of my houses/apartments.  They've been here about 6 weeks, and now they have a week off.  They all went home and are coming back in 5 days.  Would you leave the air conditioning on when they are gone, or would you turn it off and turn it back on the day they are supposed to arrive?  Their job is supposed to continue until the end of this year, so there is plenty more rent to be collected.  About $2500/week for all their places.

Leaving it on = higher electric bill.

Turning it off = house gets hot and the air conditioner freezes because it's overworked.
