What's YOUR highest circuit breaker?

Home inspector said he couldn’t check the A/C because it’s too cold. I don’t quite understand that though–I mean, you can still turn it on and see if it works and blows cold air can’t you? What is it that I don’t know here?

ETA: My realtor said don’t worry about it because the home warranty will kick in if there turns out to be something wrong with it. But I’m not sure it’d be covered in this case, with the circuit breaker problems etc.
