First: you're not stuck until morning. We run 24-hour emergency repair all winter. But a five-minute check sometimes gets the heat back on before we're even in the truck — and if not, it protects your home and speeds up our diagnosis.
What should I check on the thermostat first?
Confirm it's set to HEAT and the setpoint is above room temperature. If the display is blank or unresponsive, replace the batteries. It's the least dramatic fix in HVAC and it resolves more no-heat calls than anyone likes to admit.
Could the breaker or furnace switch be off?
Yes. Furnaces have a wall switch near the unit that looks exactly like a light switch — and gets flipped by accident. Check it, then check the breaker panel. If the breaker trips again after one reset, stop; repeated resets on a tripping circuit are how electrical problems get worse.
Can a clogged filter shut the heat off?
Yes. A fully clogged filter can shut a furnace down on safety limit. If the filter looks like felt, swap it. Make sure supply registers are open — closing vents to "push heat" elsewhere backfires.
How do I protect plumbing while the house is cold?
Open cabinet doors under sinks on exterior walls and let faucets drip slightly. Frozen pipes turn a furnace problem into a much more expensive night.
What should I tell the technician when I call?
Does the blower run? Any clicking, booming, or burning smell? Did it fail gradually or all at once? Thirty seconds of symptoms on the phone means we arrive with the right parts on the truck.
