Hurricane Season HVAC Prep: How to Protect Your System Before and After a Storm
September is still air-conditioning season in North Carolina, but it’s also an important time to think about severe weather.
When a tropical storm or hurricane threatens our area, most homeowners know to secure outdoor furniture, charge devices, and gather essential supplies. Your HVAC system should be part of your storm preparation, too.
Outdoor HVAC equipment is designed to operate outside, but severe storms can introduce additional risks, including wind-driven debris, flooding, and electrical problems. Taking a few practical precautions can help protect your equipment and help you recognize when it needs professional attention after a storm.
1. Clear Loose Items From Around Your Outdoor HVAC Unit
Start with the area surrounding your outdoor condenser or heat pump.
Before severe weather arrives, remove loose objects that could be blown into the equipment. That may include patio furniture, toys, planters, lawn equipment, fallen branches, and other unsecured items.
You can also clear away leaves and existing debris around the unit.
The goal is simple: give your outdoor equipment a clear area and reduce the number of nearby objects that could potentially strike it during high winds.
2. Don't Block Your HVAC Unit While It's Operating
Your outdoor unit needs adequate airflow to operate properly.
Avoid wrapping or covering an operating condenser or heat pump with a tarp, plastic, or another material that restricts airflow.
If you're considering additional storm protection for your outdoor equipment, particularly anchoring or flood protection, talk with a qualified HVAC professional about what is appropriate for your particular system and property rather than improvising a solution.
3. Consider Flood Risk
Wind isn't the only concern during a tropical system. Heavy rainfall and flooding can also affect HVAC equipment.
If your outdoor unit is located in an area susceptible to flooding, don't wait until a storm is approaching to think about it.
FEMA identifies elevation and relocation among the mitigation strategies that can help protect HVAC components in flood-prone locations. These are improvements that should be properly planned and installed rather than attempted as last-minute storm preparation.
If floodwater reaches your HVAC equipment, don't assume the system is safe to operate simply because the water has receded. Have potentially flood-damaged equipment professionally evaluated before using it again.
4. Know What Is Normal for Your System Before the Storm
September can still put plenty of demand on an air conditioner in North Carolina.
Pay attention to how your system is operating before severe weather arrives.
Is your AC keeping your home comfortable? Is it maintaining the temperature you've set? Is it making unusual buzzing, humming, or knocking sounds? Is the system behaving differently than usual?
Peak City recommends having unusual HVAC noises and electrical issues evaluated rather than ignoring them.
Addressing an existing problem before severe weather arrives means you'll have one less unknown to deal with afterward.
5. Check Your HVAC Filter
Check your air filter and replace it if it's dirty.
Peak City's preventative maintenance checklist includes inspecting and replacing customer-provided filters, and keeping up with filter maintenance helps support proper airflow through your system.
It's an easy item to add to your household hurricane-season checklist.
6. Inspect the Area After the Storm
Once the storm has passed and conditions are safe, visually inspect the area around your outdoor HVAC equipment before returning to your normal routine.
Look for obvious damage, fallen branches, accumulated debris, displaced equipment, or signs that floodwater reached the system.
You don't need to open the equipment or attempt electrical repairs yourself.
If the unit appears damaged, has been exposed to flooding, repeatedly trips a breaker, or makes unusual sounds when operating, stop troubleshooting and call a qualified HVAC technician.
7. Don't Ignore Electrical Problems
Severe weather can bring power interruptions and electrical problems.
If your HVAC breaker has tripped, we recommend having the system checked even if resetting the breaker restores operation.
Repeatedly resetting a breaker without identifying why it is tripping isn't a good maintenance strategy. Peak City evaluates electrical components and connections during professional HVAC maintenance.
Preventative Maintenance Can Help You Know Where Your System Stands
You can't prevent every problem a major storm might cause, but you can go into hurricane season knowing your HVAC system has been properly maintained.
Peak City's preventative maintenance includes checking system operation, thermostat performance, safety controls, electrical connections, filters, motor amp draw, capacitors, drain operation, refrigerant levels, and cooling performance.
Regular maintenance is designed to help maximize energy efficiency, reduce preventable breakdowns, and extend the life of your HVAC equipment.
