Gas odor, a carbon-monoxide alarm, smoke, arcing, or fire requires evacuation and a call to 911 or the gas utility. Burning smells, repeated breaker trips, active water leaks, no heat in freezing weather, and dangerous indoor heat for vulnerable people also need prompt action.
Technical Consideration
What to do
| Sign | Action |
|---|---|
| Gas odor or CO alarm | Leave, then call 911 or the gas utility |
| Smoke, sparks, or burning smell | Shut off power if safe; call 911 if smoke continues |
| Water pouring from air handler or boiler | Shut system off; request urgent service |
| No heat below freezing | Protect pipes; request urgent service |
| Breaker trips repeatedly | Leave it off; request diagnosis |
What comes first in a safety emergency?
Do not troubleshoot gas, smoke, or carbon-monoxide conditions inside the building. Leave and call the appropriate emergency resource.
Wait for clearance before re-entering.
How can I protect the property safely?
If there is no electrical hazard and you know the correct control, shutting down leaking or malfunctioning equipment may limit damage.
During a no-heat event, open sink cabinets and let faucets drip to reduce freeze risk.
What information speeds up help?
Share system type, symptoms, alarm messages, breaker behavior, vulnerable occupants, access instructions, and what has already been turned off.
Photos of error codes and model plates help too.
