If you have gas air conditioning.

Theoretically possible; my grandparents had a gas refrigerator. Worked
well and quiet, too.

This air conditioner is a hybrid system that can run on either gas or
electricity. Therefore, it has both an igniter and 240V service. You'd
have this if you prefer gas, but that's unreliable.

That's perfectly fine -- as long as they're all part of the same circuit.
Wire-nutting together the neutrals from two different circuits is not fine.

It's *not* OK if they're on different circuits.

Exactly.
