Power Surges Affect Your AC
December 11, 2023

In the scorching heat of summer, your air conditioning (AC) unit becomes a beacon of relief. However, power surges, often overlooked, can pose a serious threat to your AC unit’s functionality. Understanding how power surges affect your AC unit and implementing preventive measures is crucial for ensuring its longevity and optimal performance.
The Impact of Power Surges on AC Units
Power surges, sudden spikes in electrical voltage, can wreak havoc on the delicate electronic components of your AC unit. These surges can occur due to various reasons, including lightning strikes, utility grid fluctuations, and faulty wiring. The consequences of power surges on your AC unit can range from minor disruptions to severe damage, leading to costly repairs or even replacement.
1. Compressor Damage:
One of the most vulnerable components is the compressor. Power surges can overload the compressor, causing it to malfunction or fail entirely. Replacing a compressor is a significant expense, making prevention crucial.
2. Capacitor Failures:
AC units rely on capacitors to start and run efficiently. Power surges can cause these capacitors to fail, resulting in a loss of cooling capacity and increased energy consumption.
3. Electronic Control Board Issues:
The electronic control board is the brain of your AC unit, regulating various functions. Power surges can damage this critical component, leading to erratic behavior, frequent breakdowns, or a complete shutdown.

Protecting Your AC Unit
Now that we understand the potential damage, let’s explore effective ways to safeguard your AC unit from power surges.
1. Install Surge Protectors:
Invest in quality surge protectors and install them at key points in your electrical system. These devices can detect voltage spikes and divert excess energy, protecting your AC unit and other electronic appliances.
2. Whole-House Surge Protection:
Consider installing a whole-house surge protector at your main electrical panel. This provides a comprehensive defense against power surges, safeguarding not only your AC unit but also other household electronics.
3. Unplug During Storms:
Lightning strikes are a common cause of power surges. To minimize the risk, unplug your AC unit and other sensitive electronics during thunderstorms. This simple step can prevent potential damage.
4. Regular Maintenance:
Keep your AC unit in top condition through regular maintenance. Periodic inspections by a professional technician can identify and address potential issues before they escalate, reducing the risk of damage from power surges.
5. Voltage Stabilizers:
Consider installing voltage stabilizers, especially in areas with frequent power fluctuations. These devices regulate voltage, ensuring a stable supply to your AC unit and preventing damage from sudden surges.
Conclusion
In the battle against power surges, proactive measures are your greatest allies. By understanding the impact of surges on your AC unit and implementing protective strategies, you can ensure a cool and comfortable indoor environment without the constant threat of malfunction or breakdown.
