Most homes here heat with a heat pump, with electric auxiliary strips for the coldest weather. A common complaint is a heating bill that spikes without explanation, and the usual cause is auxiliary heat running when it should not — a failed sensor or a control fault leaving expensive resistance heat carrying the load the heat pump should be handling.
For the smaller number of homes with gas furnaces, the annual inspection is a safety item rather than a comfort one. Heat exchanger integrity and correct venting are what that inspection is for.

Most often auxiliary heat running when it should not. In a heat pump system, electric resistance strips are meant to supplement in genuinely cold weather.
A failed outdoor sensor, a control fault or a system stuck in emergency heat leaves them carrying the whole load, at several times the running cost.
Before the first cold snap, not during it. Systems here sit unused for most of the year and reveal their faults on the first cold night — which is the night every heating contractor in the region is already booked.
Autumn is the cheap time to find out.
Yes, and for safety rather than efficiency. The inspection checks heat exchanger integrity and correct venting, and a cracked exchanger is a combustion-gas risk regardless of how few hours the unit runs.
Light annual use does not remove that.
