Furnace Died on Christmas? What Every Inland Empire Family Should Do Next

Don't Panic — Work the Checklist

A furnace failure on Christmas Eve or Christmas Day is one of the most common emergency calls we receive. Even in the Inland Empire, overnight temperatures in December regularly drop into the 30s. If yours just quit, follow this checklist in order — many "furnace emergencies" resolve in five minutes without a technician.

Step 1: Check the Thermostat

It sounds obvious, but this is the fix in about 15% of emergency calls. Confirm:

• Thermostat is set to HEAT (not AUTO or COOL)
• Setpoint is at least 3°F above current room temperature
• Batteries are fresh (if applicable)
• Screen is on and responsive

Step 2: Check the Air Filter

A completely clogged filter can trigger a safety shutdown. If you can't remember when you last changed it, change it now. This resolves another 20% of "emergency" calls.

Step 3: Check the Furnace Switch and Breaker

There's usually a wall switch near the furnace that looks like a light switch — often labeled or unlabeled. Make sure it's ON. Then check your electrical panel for a tripped breaker labeled "furnace" or "HVAC." Reset if tripped, but if it trips again immediately, stop — that's a professional issue.

Step 4: Check the Gas Supply

If your stove uses gas, try to light a burner. No gas at the stove = no gas to the furnace. Contact your utility.

Step 5: Look at the Furnace Itself

Most modern furnaces have a small window or LED indicator. A blinking pattern indicates a specific error code — check the sticker inside the access panel or your owner's manual. Common codes:

• Slow flash: Normal, waiting for call for heat
• Rapid flash: Ignition failure or flame sensor issue
• Solid or off: Control board failure or power issue

Step 6: STOP if You Smell Gas or Notice a Sooty Smell

Leave the house immediately. Do not turn switches on or off. Call your gas utility from outside. This is a safety event, not a repair. Carbon monoxide is a serious risk with furnace malfunctions — the CDC's carbon monoxide guidance makes clear that any suspected exposure warrants immediate action.

What to Do Overnight if Repair Has to Wait Until Morning

• Gather everyone into a single small room and close the door
• Layer clothing — thin layers trap heat better than one heavy one
• Use safe space heaters (never propane or kerosene heaters indoors)
• Open cabinets under sinks on exterior walls to prevent pipe freeze
• Let a small trickle of water run from a faucet on the coldest wall
• Keep everyone hydrated — even in cold, hydration matters

Emergency Service — Even on Holidays

We keep a technician on-call for genuine heating emergencies year-round, including Christmas Day. Our furnace repair service covers Moreno Valley and the full Inland Empire with same-day response. If you're in the middle of an emergency now, don't work through a phone tree — request emergency service or call (951) 331-3310.

How to Prevent Next Year's Emergency

Almost every Christmas furnace failure was preventable. A fall tune-up catches the components that fail during the first cold snap — ignitors, capacitors, gas valves, pressure switches. Book your fall service in September or October and take Christmas off from HVAC worry. Ask about our current maintenance plan — members get priority emergency dispatch.
