HVAC Not Working After Power Outage: What To Do With Your Unit After A Natural Disaster

Living in the Carolinas, we know that severe weather—hurricanes, tornadoes, and flooding—can happen unexpectedly. Your home's HVAC system plays a critical role in maintaining comfort, but it's important to prioritize safety after any natural disaster before attempting to turn on your heating or air conditioning unit. At CALL DAD, we specialize in residential HVAC services and are here to help you navigate these crucial steps. 

^{Inspecting Your HVAC Unit for Damage After a Natural Disaster} 

Before you even consider turning on your HVAC system, take the following safety precautions:

^{1. Look for Visible Damage} 

• Flooding: If your area has experienced flooding, your HVAC unit may have been submerged in flood water. Check for visible water damage, especially around the outdoor unit (condenser). Electrical components exposed to water can be dangerous, and powering up the unit prematurely can lead to costly repairs or further damage.
• Wind Damage: Hurricanes and tornadoes can throw debris at high speeds. Inspect the outdoor unit for dents, missing panels, or bent fan blades. If debris has entered the unit, internal damage may have occurred.
• Electrical Components: Look for signs of electrical damage, such as exposed wires or broken connections, around your system. Flooding can cause short circuits or blow fuses, while high winds may have dislodged key components.

^{2. Check the Circuit Breaker} 

Strong winds or surges from storm damage can cause your circuit breaker to trip. Before assuming the worst, check your electrical panel to see if the HVAC system’s breaker has been flipped to the “off” position. Additionally, it is crucial to inspect the entire system after a power surge to ensure all components are functioning properly and to prevent further damage.

^{3. Remove Debris Around the Unit} 

If debris, such as branches or leaves, is piled around your outdoor condenser unit, clear it away. It is also important to check both indoor and outdoor components of a split system for debris. This ensures proper airflow and can help prevent future damage to the system. However, don’t attempt to open the unit or remove internal debris unless you’re a professional.

^{4. Inspect for Gas Leaks and Serious Health Hazards Involved (for Gas Heating Systems)}

In the aftermath of a tornado or hurricane, gas lines can become damaged. It is also crucial to check electric furnaces for damage, as they are at risk of corrosion and other reliability issues if exposed to floodwater. If you smell gas or suspect a leak, leave the premises immediately and contact your utility provider. Never attempt to power on a gas furnace or HVAC unit if you suspect there’s a gas leak.

^{What to Do If Your HVAC Unit Doesn’t Turn On}

Even if everything appears normal, your HVAC system may still fail to power on after a natural disaster. Here’s what you should do:

^{1. Double-Check the Thermostat} 

Before assuming there’s a larger issue, check your thermostat. If the thermostat isn’t functioning properly, it is also important to check the refrigerant system to ensure there are no leaks or damage. If the thermostat isn’t functioning properly, your HVAC unit won’t turn on. Ensure it has power, is set to the right mode (cooling or heating), and that the settings haven’t been accidentally changed during the storm.

^{2. Listen for Unusual Noises} 

If the system is attempting to start but isn’t running smoothly, it could be an indicator of internal damage. It is important to check the air conditioner for unusual noises. Unusual sounds like grinding, clanking, or buzzing are signs that something isn’t functioning properly inside the unit. Turn it off immediately to prevent further damage and call a professional.

^{3. Call a Professional for an Inspection} 

Even if your HVAC system seems okay, having a professional inspect it is the safest course of action. It is especially important to have a professional inspect the HVAC equipment to ensure it remains safe and functional during severe weather events. At CALL DAD, our team of trained technicians can ensure your system is working safely and efficiently after severe weather. We’ll check for electrical issues, internal damage, and perform any necessary repairs or maintenance to prevent future issues.

^{When to Replace or Restore Your HVAC Unit After a Natural Disaster}

In some cases, severe flooding or wind damage may mean that your HVAC unit requires replacement rather than repair. It is crucial to assess flood damaged HVAC systems to determine if they need replacement. If your system has been submerged in water or experienced extensive physical damage, repairs may not be cost-effective or safe. Call a professional to assess the extent of the damage and provide you with the best course of action.

^{Safety Precautions for Your HVAC System}

After a natural disaster, it’s crucial to take safety precautions before using your HVAC system. Here are some essential steps to follow:

1. Perform a Visual Inspection: Look over your HVAC system for any visible signs of damage. Check for water damage, debris, or any issues with the electrical components.
2. Check for Electrical Hazards: Ensure there are no exposed wires or water damage to the electrical components of your system. These can pose serious safety risks.
3. Replace Filters: Even if your system appears undamaged, replace the filters. This helps maintain good air quality and ensures your system runs efficiently.
4. Test Carbon Monoxide Detectors: Make sure your carbon monoxide detectors are functioning correctly. This is especially important if you have a gas furnace.
5. Check for Blockages: Inspect your HVAC system for any blockages or malfunctions that could lead to carbon monoxide emissions. Safety should always be your top priority.

Taking these precautions can help ensure your HVAC system is safe to use after a disaster.

‍

^{Flood Damage and Insurance Coverage}

Flood damage to your HVAC system can be extensive and costly. Understanding your insurance coverage and available assistance can help ease the financial burden. Here’s what you need to know:

1. Flood Insurance: Check if your homeowner’s insurance policy includes flood insurance. This coverage can help cover the cost of restoring your HVAC system after flood damage.
2. FEMA Assistance: If you live in a federally declared disaster area, you may be eligible for assistance from FEMA. This can help cover the cost of replacing or cleaning and testing your HVAC system.
3. Document Damage: Take photos and videos of the damage to your HVAC system. This documentation is crucial for supporting your insurance claim.
4. Contact Your Insurance Provider: Report the damage to your insurance provider as soon as possible. They can guide you through the claims process and help you understand your coverage.

By understanding your insurance options and documenting the damage, you can streamline the process of restoring your HVAC system.

‍

^{Power Outages and HVAC Systems}

Power outages are common during natural disasters and can impact your HVAC system. Here’s what you need to know to protect and reset your system:

1. Power Surges: Power surges can damage the sensitive electrical components of your HVAC system. Installing a surge protector or a whole-house surge protection system can help prevent this.
2. Surge Protection: Ensure your HVAC system is protected from power surges by installing a surge protector. This can safeguard your system from electrical damage.
3. Reset the System: After a power outage, reset your HVAC system by turning off the power and then turning it back on. This can help clear any faults caused by the outage.
4. Check for Damage: Before turning your system back on, inspect it for any signs of damage, such as water damage or electrical issues. Ensuring your system is in good condition can prevent further problems.

By taking these steps, you can help protect your HVAC system from the effects of power outages.
