Emergency No-Heat Furnace Repair in Big Bear
Free referrals to independent local heating contractors serving Big Bear Lake, Big Bear City, and nearby mountain communities.
If your Big Bear furnace stops working on a cold night, first rule out gas smells and carbon monoxide, then check the thermostat, breaker, filter, and snow-covered vents. If heat doesn't return, call for emergency repair and protect your pipes by opening cabinet doors and dripping faucets. After-hours labor often costs more.

What should you do first when the heat goes out?
- Safety first. If you smell gas or a CO alarm is sounding, leave the house and call 911 or Southwest Gas from outside.
- Quick checks. Thermostat on Heat and set above room temperature, furnace switch and breaker on, filter not clogged, blower door closed.
- Look outside. On high-efficiency furnaces, the two white PVC pipes must not be buried in snow or capped with ice. Clear them gently by hand.
- Reset only once. Many furnaces lock out after several failed ignition attempts. Turning power off for a minute and back on can clear a lockout one time. If it locks out again, stop and call.
How do you keep pipes from freezing while you wait?
- Open sink cabinet doors on outside walls so room air reaches the pipes.
- Let a pencil-thin stream of cold water run from the faucet farthest from the main.
- Close doors to unused rooms and keep the warmest room occupied.
- Use space heaters only if they are listed for indoor use, plugged directly into the wall, and at least 3 feet from anything that burns. Never use a gas oven, grill, or camp heater indoors.
Why do furnaces fail most on the coldest nights?
The coldest nights are when the furnace runs longest. Weak ignitors, dirty flame sensors, failing inducer motors, and clogged filters often show up then. On high-efficiency units, condensate lines can freeze, and drifting snow can block intake and exhaust pipes.
What does an emergency visit cost?
National estimates from HomeGuide put most furnace repairs at $125 to $480, but emergency labor often runs $140 to $210 per hour compared with $75 to $150 during normal hours. Ask for the trip or diagnostic fee and the after-hours rate when you call.
When should you call an emergency furnace pro in Big Bear?
Call for urgent help, and leave the house first where noted, if any of these apply:
- You smell gas (a rotten-egg odor): leave right away without flipping switches, then call 911 or your gas utility (Southwest Gas in the Big Bear Valley) from outside.
- A carbon monoxide alarm sounds, or people feel headache, dizziness, or nausea that eases outdoors: get everyone into fresh air and call 911.
- There is no heat and indoor temperatures are dropping toward freezing, especially with infants, older adults, someone with a medical condition, or water pipes at risk.
- The furnace trips the breaker repeatedly, smells like burning wiring, or shows scorch marks.
- You see flames outside the burner area, heavy soot, or a lazy yellow flame instead of a steady blue one.
- A vacant cabin's thermostat or smart sensor reports the house is losing heat during a cold spell.
If you smell gas or a carbon monoxide alarm goes off, leave the building first and call 911 or your gas utility from outside. Don't wait for a contractor.

What do people ask about furnace repair in Big Bear?
Is no heat considered an emergency?
It can be. In a home at Big Bear's elevation, losing heat during freezing weather risks frozen pipes, and it can be dangerous for infants, older adults, and people with medical conditions. Say so when you call so the contractor can prioritize.
Should I keep resetting the furnace?
No. One power reset can clear a lockout, but repeated resets can hide a safety problem. If the furnace locks out again, leave it off and call.
Can I run a space heater overnight?
Only an electric heater listed for indoor use, with tip-over and overheat shutoff, plugged directly into a wall outlet, and kept at least 3 feet from bedding, curtains, and furniture. Never use fuel-burning camp heaters or ovens for heat indoors.
