How to Protect Your HVAC During Storms?

Step 1: Secure the Outdoor Unit

The outdoor unit of your HVAC system is one of the most exposed parts of your home and requires proper safeguarding during severe weather.

• Clear the Surrounding Area: Remove loose items like garden tools, furniture, or decorations nearby. High winds can turn these into dangerous projectiles that damage the unit.
• Trim Nearby Vegetation: Cut back branches or overgrown plants that could break off and hit the unit during a storm.
• Use a Protective Cover: A heavy-duty, weather-resistant cover shields the unit from hail, rain, and flying debris. Ensure the cover is snug and doesn’t restrict necessary ventilation.
• Anchor the Unit: Secure the system with storm straps or ground brackets to keep it steady in strong winds. This prevents tipping or displacement.

Step 2: Turn Off the HVAC System

During a storm, your HVAC system is at risk of damage from power surges, water exposure, and debris. Turning it off can help protect its components.

• Switch Off at the Thermostat: Turn the system off at the thermostat to prevent it from running during the storm.
• Shut Off Power at the Breaker: Locate your home’s electrical panel and switch off the circuit that powers your HVAC. This step prevents electrical surges caused by lightning strikes or grid interruptions from damaging internal parts.
• Avoid Using the System: Resist the urge to turn it back on during the storm, even if there’s a temporary calm. Wait until the weather has cleared completely.

Step 3: Inspect for Damage Post-Storm

Inspect your HVAC unit after the storm has passed to determine if it’s safe to use and hasn’t sustained damage.

• Check for Visible Damage: Look for signs of impact, such as dents, bent fins, or debris around the outdoor unit. Ensure no parts appear loose or dislodged.
• Inspect for Flooding: If water has pooled around the unit, do not attempt to turn it on. Water exposure can damage internal components or cause electrical issues.
• Assess Electrical Connections: Ensure the power supply and wiring appear intact. Call a professional before using the system if you notice exposed wires or burnt marks.
• Listen for Unusual Sounds: Once it’s safe to restart, notice any strange noises, like rattling or buzzing, which may indicate internal damage.

Step 4: Add Protective Measures

Take additional steps to fortify your HVAC system to prevent future storm damage. These measures enhance protection and reduce the risk of costly repairs.

• Install Surge Protectors: Protect your HVAC system from electrical damage caused by lightning strikes or power surges with dedicated surge protectors.
• Elevate the Outdoor Unit: In flood-prone areas, raise the unit on a platform to protect it from water damage.
• Use Protective Cages or Covers: Consider installing a metal cage or permanent protective housing to shield the outdoor unit from flying debris and impacts.
• Secure Permanent Anchors: In regions prone to high winds or hurricanes, install heavy-duty brackets to keep the unit securely in place.
