It is approximately correct as long as the temperature deltas are approximately the same for heating vs cooling.
(And as long as we're dispelling generalizations: Those deltas do vary wildly based on local climate, such that they're impossible to generalize and typify.
For instance: The city of Saint Paul, Minnesota [USA] has a very different climate compared to the city of São Paulo in Brazil, with accordingly-different heating/cooling deltas.
