Before you call
Quick checks you can do yourself
- Set the thermostat to Heat, a few degrees above room temperature.
- Replace the furnace filter if it is dirty.
- Make sure the furnace door is closed tightly; a loose panel keeps it from starting.
- Check the furnace power switch (looks like a light switch) and its breaker.
- If you smell gas, do not touch anything: leave the house and call SoCalGas or 911.
Still not working? Call (323) 240-2373 or tap "Call me back". Do not open electrical panels or touch gas parts.

Furnace Blowing Cold Air? 7 Causes and What to Check
A furnace that blows cold air is often just set to fan On instead of Auto, or the burners shut off after a few seconds because of a dirty flame sensor, a clogged filter, or an ignition problem. Check the thermostat and filter first. If the burners do not light or keep shutting off, call a technician.

Furnace Turns On Then Shuts Off? Short Cycling Causes
A furnace that turns on and shuts off quickly is short cycling, usually because of a clogged filter causing overheating, a dirty flame sensor, a blocked vent or intake, or a thermostat problem. Replace the filter and check the thermostat first. If it keeps cycling, a technician should check the safety switches and venting.

Heat Pump Blowing Cold Air in Heat Mode? Causes
A heat pump that blows cool air in heat mode may simply be in defrost mode, which is normal and lasts a few minutes. If it blows cold air for a long time, check the thermostat mode and filter, then call a technician for possible reversing valve, defrost control, or refrigerant leak problems.

Dirty flame sensors and weak igniters fail first.

Every home with gas appliances should have working CO alarms.
Pro tip
Book the furnace tune-up in September or October, before the first cold snap fills the schedule.
