Winter is not the same
Cold shifts charging behavior in ways users forget by spring. The gaps that open are rarely technical; they are duties nobody pinned down while the weather was still warm and forgiving, and a mild autumn is the worst time to assume winter will be fine.
The sound view
Settle the boundary of responsibility early. Winter makes vague agreements expensive, so write who does what before the temperature drops and the fault actually arrives on a freezing morning, because no one wants to negotiate blame in the snow.
Plan the season
Build a seasonal maintenance plan and put wear parts on a replacement cycle. This lowers the odds of sudden failure when demand peaks in the cold and crews are stretched thin already, and a planned part swap beats an emergency truck roll. A planned part swap beats an emergency truck roll, and the winter that was prepared for in autumn is the one that passes without the call nobody wanted to receive on the coldest night.
