An inspection on our home (7years old) recently revealed that both our
air conditioning units have 40 amp circuit breakers instead of 30 amp
(the unit asks for 30 amps). How big of a deal is this? And if so, is
it an expensive thing to change?

Thanks in advance.


With this amount of information impossible to tell.

The maximum overcurrent device of an air conditioner needs to be adhered to,
just good sense.
Changing the disconnect at the unit to a fusible pull out is fairly cheap
and easy to do.
Depending on the length of the circuit just changing the breaker to a 30 may
create more problems.
