    Why neutral and hot reversed only when a/c is turned on?

    I have tenants that have 3 fairly new small a/c units all the same and when any of them are turned on my tester reads hot & neutral reversed. The 15 amp circuit that feeds these units has no ground wire. Is this normal or could these a/c units be wired wrong from the factory?
