Can Extreme Weather Damage AC Units?
Homeowners should be aware of the potential risks and take preventive measures to protect their AC systems.
Below are some common ways extreme weather can damage AC units.
- Effects of High Winds on AC Units
Strong hurricane winds can damage outdoor AC units. Winds over 100 mph can bend or break fan blades, leading to expensive repairs. Units in open areas are especially vulnerable to being toppled, which impacts their performance.
- Risks from Flying Debris
Debris is blown into the air by high winds and storms and can damage air conditioning units, particularly the condenser coils. If debris accumulates close to the unit, it will block airflow and make the system work harder, losing efficiency.
- Flooding and Water Damage
Flooding can short out electrical components in the unit and damage it. Long-term exposure can lead to rust and corrosion, which can wear down the unit over time.
- Power Surges and Electrical Issues
Power surges from storms can damage HVAC systems by blowing fuses or tripping circuit breakers. Power outages can also halt cooling, making backup power sources essential for maintaining comfort during extreme weather.
- Corrosion from Exposure to Saltwater
In coastal areas, saltwater can harm metal parts like condenser coils.
- Physical Damage from Storm Impact
Severe storms can harm AC units, causing dents or bent parts. Ignoring these issues can lead to bigger problems and more expensive repairs.
Signs of AC Unit Damage After Storms
Severe weather can take a toll on an air conditioning system, leaving homeowners with unexpected repair costs and discomfort. After a storm, it’s important to assess your AC unit for any signs of damage to prevent further issues.
Here are some key indicators that your system may need attention:
Burning Smell or Electrical Odors
A burning or electrical smell often indicates that electrical parts have shorted out. Ignoring these smells increases the fire risk.
Unusual Noises from the Outdoor Unit
Rattling, grinding, or screaming sounds may be due to loose parts, motor issues, or refrigerant leaks, which can result in costly damage if not inspected promptly.
Reduced Cooling Performance
When an air conditioning system does not cool effectively, it can be due to refrigerant leaks or airflow obstruction, which may be worsened by storms.
Ice Formation on Coils
Ice on the coils of an air conditioning system can be a sign of obstructed airflow or refrigerant leak, and the outdoor unit vents can be obstructed by storm debris. Neglecting ice buildup can destroy the compressor and be very costly to fix.
Physical Damage or Dents
Dents on the outdoor air conditioning unit can lead to weak airflow and efficiency issues. It’s essential to schedule repairs to restore its performance.
How to Protect AC Units from Extreme Weather
Severe weather conditions such as storms, floods, and high winds can cause extensive damage to air conditioning units. By taking preventative steps for your HVAC systems, you can make them run more efficiently and last longer.
Below are some simple steps homeowners can take to protect their AC units from harsh weather conditions:
- Secure the Unit to Prevent Movement
Securing the outdoor unit prevents damage during storms, especially tornadoes. Anchoring it to a concrete slab with bolts or brackets keeps it stable, and using ratchet straps or stakes offers extra support.
Regular inspections are needed to ensure the anchoring works in all weather conditions.
- Clear the Area Around the Unit
To ensure the AC unit works well, clear debris and trim bushes for good airflow. Outdoor furniture can pose a danger during storms and might damage the unit.
Regular landscaping and debris removal before bad weather can help reduce this risk.
- Cover the Unit During Storms
A strong cover protects the AC unit from debris and hail. Weatherproof covers guard against harsh weather.
After a storm, take off the covers to prevent moisture buildup, which can cause rust or electrical problems later.
- Elevate the Unit to Avoid Flooding
Flooding can harm air conditioning units, especially in areas that are prone to floods. Elevating outdoor units on a sturdy platform keeps them safe from water.
Additionally, ensuring proper drainage around the installation site prevents water accumulation and lowers climate risks.
- Install Surge Protection Devices
Lightning strikes and power outages can harm HVAC electronics. Installing a surge protector provides extra safety, and regular inspections help ensure it works effectively.
- Shut Down the Unit Before a Storm
Before a storm, turn off the AC to prevent electrical damage from water or power surges. Make sure everyone in the household is aware of this plan.
After the storm, inspect the unit carefully before turning it back on.
Protecting your AC unit from extreme weather can save you from costly repairs and unexpected breakdowns. With the right precautions, you can keep your system running efficiently no matter the conditions.
