Leave first. Call from outside.
If you smell gas or suspect a gas leak, leave the building immediately. From a safe place outside, call 911 and your gas utility. Avoid operating switches or devices in the building. Let responders determine when it is safe to return.
Treat a carbon monoxide alarm as urgent
Get everyone outside to fresh air and call 911 if a carbon monoxide alarm sounds or you suspect poisoning. Symptoms can include headache, dizziness, weakness, nausea, or confusion. Seek emergency help rather than using this website to diagnose the situation.
Keep temporary heating safe
Use portable heating equipment only as directed by its manufacturer. Outdoor fuel-burning equipment belongs outdoors; a stove or oven is not a space heater. If you cannot keep the home safely warm, arrange a safe place to stay.
Leave repairs to qualified professionals
Fuel, electricity, hot water, pressure, combustion, and refrigerants create risks that general online guidance cannot assess. Keep safety devices intact and leave equipment panels and repair work to qualified professionals.
This website cannot dispatch help
Denver Heating Repair is a VisibilityReady™ demonstration, not a heating provider or an emergency service. For a non-emergency heating problem, use the loss-of-heat guide to organize the information for a provider you arrange independently.
