No Heat

A dead heating system in subzero weather moves ahead of routine work, so call and say what time it stopped.

When this becomes an emergency

What a pro does

Power comes first, because a system with no power looks exactly like one that's failed. That means the breaker, the service switch beside the unit, the door interlock on the blower panel, and the low-voltage fuse on the control board, all of which are cheap to check and expensive to overlook. Once power is confirmed, attention moves to the thermostat circuit and then through the ignition sequence in order, watching for whichever safety device pulled the plug. Most no-heat calls end at a control that did its job correctly for a reason worth finding. Throwing parts at the symptom is how people pay twice.

Frequently asked questions

Yes, and so is the plain wall switch beside the equipment, which gets flipped by anyone mistaking it for a light.
Cold air settles. A thermostat mounted at shoulder height reads the warmest layer in the room, so the living space feels worse than the number on the display.
Once is fine. A breaker that trips again immediately is reacting to a real fault, and repeated resets risk damage to the control board or the motor drawing the current.
It does. An interlock switch behind that panel cuts power when the door is off, so a panel left slightly proud after a filter change can leave a perfectly good furnace dead.
