A properly sized system will be based upon the worst of the heating or cooling conditions.

Luckily an inverter heat pump can run down to about 25% full load so even with them coupled and in an imbalanced heat/cool environment you can still see good performance year round.

They are required by code to do a load calculation, so you might wish to continue shopping around until you find one to do it.
