When this becomes an emergency

What a pro does

Nine times out of ten this starts at the electrical panel and the service switch, not at the equipment. Those switches sit at the head of the basement stairs in a lot of older homes, look exactly like a light switch, and get flipped by anyone carrying laundry past them. A tech confirms power, then the low-voltage side, then the thermostat's call, then the sequence the equipment runs when it receives one. Each stage either passes the call along or it doesn't, and finding the break is mostly a matter of working that chain in order rather than opening panels at random. Something else worth naming: a total outage often turns out to be a safety device that did its job. Blocked venting, an overheated limit, a flooded condensate trap. Replacing whatever tripped without asking why it tripped just sets up the next outage. Verifying carbon monoxide alarms have working batteries comes first regardless.

Frequently asked questions

It's the service disconnect for the heating equipment, wired to look like an ordinary light switch. Flipping it off cuts the unit dead, and it's one of the most common reasons a system appears to have failed completely.
No. A lit screen only proves it has power. The call for heat travels over separate wiring, and a broken conductor or a loose terminal will leave the display looking perfectly normal.
Open cabinet doors under sinks on exterior walls, keep interior doors open so warmth spreads, and consider closing the water main if temperatures inside are heading toward freezing.
Not necessarily. Electrical faults and tripped safeties produce a silent stop, and those are often less serious than a failure that announced itself with grinding or banging beforehand.
