Gas and Carbon Monoxide Safety
If you smell gas or suspect a carbon monoxide leak, leave the building immediately, call your gas utility or 911, and do not operate any HVAC equipment. Do not attempt to repair a gas appliance yourself.
After the immediate hazard is cleared by your utility or emergency services, request professional HVAC repair to inspect and repair the equipment.
Install and maintain carbon monoxide detectors on every floor of your home. If a detector alarms, treat it as an emergency and evacuate.
When to Request Emergency HVAC Service
Request emergency service for no heat during freezing weather, no cooling during a heat advisory, a furnace or boiler that has stopped working, or an AC failure in extreme heat.
For burning smells, unusual noises, or warning signs from your equipment, see our HVAC emergency warning signs guide before deciding whether to request immediate service.
