Limit switches, pressure switches and inducer motors checked in order.
Overheating from restricted airflow, a dirty filter or an oversized furnace.
Banging, squealing or a burning smell checked before the next cold night.
Venting, heat-exchanger visual check and carbon monoxide concerns raised in plain language.
