HVAC Earthquake Risks
Earthquakes can topple outdoor units, rupture gas lines, break refrigerant connections, and damage ductwork. Proper securing prevents many issues.
Outdoor Unit Securing
Equipment should be bolted to a concrete pad. Vibration isolators help but shouldn't replace proper anchoring. Check your unit's mounting.
Flexible Gas Connections
Modern code requires flexible gas connectors for furnaces and water heaters. These connections can withstand seismic movement without rupturing.
Automatic Gas Shutoffs
Consider installing a seismic gas shutoff valve. These automatically close when earthquake shaking is detected, preventing gas leaks and fires.
Post-Earthquake Safety Checks
After an earthquake, smell for gas (leave immediately if detected), visually inspect equipment, and have a professional check before resuming operation.
Emergency Preparedness
Know how to manually shut off gas. Have flashlights accessible. Keep a professional's contact information handy for emergency service.
