Gas Smell Near the Furnace or Water Heater

What to do right now if you smell gas in a Utah home: leave, then call 911 and Enbridge Gas Utah from outside.

Safety first. If you smell gas (a rotten egg smell) or hear hissing near a gas appliance, leave the building now. Do not use light switches, phones or anything that can spark inside. From a safe place, call 911 and your gas company (Enbridge Gas Utah emergency line: 1-800-767-1689). (Source: Enbridge Gas) If a carbon monoxide alarm sounds or people feel headache, dizziness, nausea or confusion, get everyone outside to fresh air and call 911. (Source: U.S. Centers for Disease Control and Prevention; U.S. Environmental Protection Agency) Do not try to repair gas, refrigerant or electrical parts yourself.

Do this first. Get everyone outside. Call 911 from outside. Do not stay to look for the problem.

Can I fix this myself?

Only the simple checks listed above. Gas, refrigerant and electrical work needs a trained HVAC technician.

Can this site tell me what is wrong with my furnace or AC?

No. Utah HVAC Help is general information, not a diagnosis. Gas, refrigerant and high-voltage electrical parts need a trained HVAC technician. If you smell gas or a CO alarm sounds, leave the building and call 911 and your gas company from outside.
