Living in Florida means preparing for hurricane season every year. While most homeowners focus on stocking supplies, securing windows, and protecting outdoor furniture, one important piece of equipment is often overlooked... Your air conditioner. Your HVAC system is one of the most expensive appliances in your home, and hurricanes can expose it to high winds, flying debris, flooding, power surges, and lightning. Fortunately, a little preparation before the storm can go a long way toward helping protect your investment.

Before a storm arrives, walk around your outdoor condenser and remove anything that could become airborne in high winds. This includes:

• Patio furniture 
• Potted plants 
• Garden decorations 
• Trash cans 
• Lawn tools 
• Toys 
• Loose branches 
• 
  

Even lightweight objects can become dangerous projectiles during hurricane-force winds and damage your outdoor unit.

As a hurricane approaches, it's a good idea to turn your air conditioner off at the thermostat.

If local officials expect widespread power outages, you can also turn the HVAC breaker off before the storm arrives. This helps reduce the risk of electrical damage caused by repeated power interruptions, voltage fluctuations, and sudden power restoration. Once the storm has passed, wait until power has been stable before turning your system back on.

Many homeowners think of surge protectors for televisions and computers, but your air conditioner is one of the most expensive electrical appliances in your home. Power surges caused by lightning strikes or utility restoration can damage sensitive HVAC components, including:

• Capacitors 
• Contactors 
• Circuit boards 
• Compressors 

Installing a professionally installed HVAC surge protector can provide an extra layer of protection during Florida's storm season. 👉 Related Article: Why Every Florida Homeowner Should Consider HVAC Surge Protection Before Hurricane Season

This is one of the questions we hear most often. Generally, no.

Your outdoor air conditioner is designed to withstand normal rain and weather conditions.

If a hurricane is approaching, placing a tarp or plastic cover over the unit can actually become a hazard if it isn't properly secured. If your manufacturer recommends a hurricane cover, use only a properly fitted, breathable cover and remove it as soon as conditions are safe after the storm passes. Never operate your air conditioner while it's covered.

Many homeowners worry that heavy rain will damage their air conditioner.

Fortunately, your outdoor condenser is built to operate in rain.

The bigger concerns during hurricanes are:

• Flying debris 
• Floodwater 
• Saltwater intrusion 
• Power surges 
• Falling tree limbs 

Rain alone rarely causes damage.

If your air conditioner has been submerged or partially submerged by floodwater, do not turn it back on. Floodwater may contain mud, salt, chemicals, and debris that can damage electrical components and create safety hazards. Instead:

• Leave the system turned off. 
• Inspect the area for visible damage. 
• Contact an HVAC professional before restarting the system. 

Attempting to operate a flooded system can lead to additional damage and may create electrical hazards.

Once it's safe to go outside, take a few minutes to inspect your outdoor unit. Look for:

• Fallen branches 
• Bent fan guards 
• Damaged refrigerant lines 
• Loose electrical disconnects 
• Standing water around the unit 

If you notice significant damage, keep the system off until it can be inspected.

Power often flickers several times after a hurricane as utility crews restore service.

Allow power to remain stable before restarting your air conditioner.

If your system doesn't start normally after power has been restored, don't continue resetting breakers or cycling the thermostat.

Call an HVAC professional to diagnose the problem safely.

Before the Storm

✅ Remove loose objects around your outdoor unit.

✅ Turn your thermostat off before severe weather arrives.

✅ Consider switching off the HVAC breaker if extended outages are expected.

✅ Install HVAC surge protection.

After the Storm

✅ Wait for stable power.

✅ Inspect the outdoor unit.

✅ Remove debris.

✅ Never restart a flooded system.

✅ Call a professional if anything looks damaged.

Every hurricane season, we receive calls from homeowners asking if they should cover their air conditioner or turn it off before the storm. The best thing you can do is prepare ahead of time. Secure the area around your outdoor unit, protect your system from power surges, and never restart an air conditioner that's been flooded. A few simple precautions before the storm can help prevent costly repairs afterward.

Yes. Turning your thermostat off before the storm helps protect your system from repeated power interruptions and voltage fluctuations.

No. Outdoor air conditioning units are designed to operate in normal rain. Floodwater, flying debris, and power surges are much greater concerns.

In most cases, no. Unless your manufacturer specifically recommends a fitted hurricane cover, it's generally better to leave the unit uncovered. Never use plastic or a loose tarp, and never run the system while it's covered.

Yes. Lightning and power surges can damage electrical components such as capacitors, contactors, control boards, and compressors. HVAC surge protection can help reduce that risk.

Do not restart it. Floodwater can damage electrical and mechanical components. Have the system inspected by a qualified HVAC technician before turning it back on.
