Respond to HVAC Sparks or Smoke Emergencies

Cost Savings

Checklist Tasks

• Shut off the main HVAC breaker to instantly cut power and prevent fire escalation.
• Inspect the HVAC unit for melted wires or burnt connectors to find sparking sources.
• Check for lingering smoke or odors in nearby rooms to detect hidden duct fires.
• Photograph all visible damage before touching components to document for insurance.
• Feel ductwork and walls for abnormal heat to spot possible internal fire spread.
• Remove flammable items within 6 feet of the unit to reduce ignition risk.
• Test carbon monoxide and smoke detectors to ensure they work during the emergency.
• Do not reset or restart the HVAC until a licensed technician inspects all components.
• Record the model and serial numbers for accurate emergency service requests.
• Check the air filter for scorching or soot, which may reveal airflow ignition points.
• Inspect thermostat wiring for melting or discoloration to catch electrical faults.
• Ventilate by opening windows and doors to disperse smoke and reduce inhalation risk.
