Furnace failures during cold snaps cause ER visits and burst pipes. Covers backup heat sources, emergency heating safety, pipe freeze prevention during outages, and generator integration.
Prepare Before the Outage
Step 1: Know your furnace shutoff and how to restart it. Step 2: Have backup heat sources ready: space heaters (one per main living area), fireplace or wood stove with dry wood, and propane heater with carbon monoxide detector. Step 3: Winterize pipes. Step 4: Have emergency contact numbers for your HVAC company and plumber. Step 5: Consider a portable generator that can power your furnace blower. Never use generators indoors or in attached garages.
Heating Safety During Outages
Carbon monoxide is the #1 danger during winter outages. Never use kerosene heaters, propane camp stoves, or charcoal grills indoors—they produce lethal CO. Place all fuel-burning heaters on a non-flammable surface. Ensure working CO detectors on every level. Keep fire extinguisher accessible. If using a generator, run it at least 20 feet from the house with exhaust pointing away from windows and doors.
