Know when to leave rather than troubleshoot

Leave for a natural-gas odor or carbon-monoxide alarm and contact the gas utility or emergency services from a safe location. Do not operate switches, flames, vehicles, or HVAC equipment in the affected area.

Turn equipment off for urgent mechanical or electrical signs

Smoke, sparking, a burning electrical smell, repeated breaker trips, severe banging or grinding, water near electrical components, and rapidly spreading leakage warrant shutdown and professional guidance.

Prepare concise information for dispatch

Share the safety condition first, then the system type, observed symptoms, when they started, which components still operate, and whether children, older adults, pets, or vulnerable occupants are affected by indoor temperatures. Same-day appointments may be available subject to technician availability. No-heat and no-cooling calls receive priority dispatch seven days a week; priority dispatch does not guarantee arrival or repair completion.
