How do you avoid surprises?
Ask for the diagnostic or trip fee when you call, get a written estimate before work begins, and ask whether the fee is credited toward the repair.
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.

It depends on the furnace's age and condition. HomeGuide suggests considering replacement for units that need frequent repairs or are more than 20 years old.
