Does Your System Have HVAC Surge Protection?
If you find yourself pondering this question, your HVAC system may still be vulnerable to power surges. To protect your system from these unpredictable events, consult a skilled HVAC technician from Wilcox Energy. They will offer tailored advice and solutions to enhance your system’s resilience to power surges and unexpected power failures.
Understanding Power Surges
A power surge occurs when an unexpected spike in electrical voltage surpasses the standard levels within a power supply system. Such surges often result from abrupt electricity flow disruptions caused by lightning strikes or power outages. Additionally, the activation or deactivation of large electrical appliances, including air conditioners, refrigerators, or elevators, can trigger these voltage spikes.
Although a power surge may last only a brief moment, typically just a fraction of a second, its effects can be devastating. The surge of excess electrical energy can overload and harm the delicate electronic components within devices and appliances. This damage can cause them to malfunction or, in severe cases, lead to complete failure.

Differentiating Power Surges, Power Outages, and Brownouts
Power surges, power outages, and brownouts all stem from issues within the electrical power supply, yet they each describe distinct phenomena. Here’s a concise overview:
- Power Surge: This refers to a rapid and transient spike in electrical voltage, usually enduring merely a fraction of a second. Triggered by lightning strikes, power outages, or the activation of high-powered electrical machinery, power surges can damage electronic devices and appliances. Using surge protectors is commonly advised.
- Power Outage: This event occurs when the electrical power supply to a specific building or region is interrupted, leading to a total loss of power. Various factors, such as severe weather conditions, equipment failures, or planned maintenance activities, can trigger power outages.
- Brownout: This occurs when voltage is reduced within the electrical power supply system. The effects of a brownout are typically noticeable, such as dimming or flickering lights and reduced power to appliances. Causes of brownouts include excessive demand on the power grid, equipment malfunctions, or issues within a building’s or area’s electrical system.

HVAC Components Vulnerable to Power Surges
Power surges can compromise several critical components of an HVAC system, potentially leading to significant functionality issues and repair costs.
HVAC Control Board
Often referred to as the “brain” of the HVAC system, the control board is crucial for proper function but vulnerable to damage from power surges. A compromised control board disrupts communication with the thermostat, leading to malfunctions in heating or cooling. This can significantly impact comfort levels, particularly during periods of extreme temperatures.
HVAC Compressor Motor
The compressor motor in your HVAC system, identifiable as a box from which wires protrude, plays a pivotal role by compressing low-pressure, cool refrigerant into a high-pressure, hot state.
This motor, the heart of the compressor, is particularly prone to damage from power surges. It consists of numerous wires that transform electrical energy into kinetic energy. A surge can cause these wires to overheat and potentially combust. If the motor is damaged, it will not function properly, causing a failure in the compressor’s overall operation.
HVAC Relay Switch
The relay switch in your HVAC system activates or deactivates certain high-voltage components. Typically, this switch includes an electrical contactor surrounded by a coil. Should the voltage exceed specific levels, the coil is prone to burning out, leading to a broken circuit and causing the relay switch to malfunction.
HVAC Capacitor
The capacitor, an essential oval-shaped component within your HVAC system, stores the electrical charge to power various electrical components. If exposed to a power surge, the capacitor may sustain damage, potentially disrupting the smooth operation of your HVAC system and causing performance issues.

- Use High-Quality Wiring: High-quality wiring and components significantly reduce the likelihood of power surges damaging your HVAC system. Hiring a professional electrician to conduct the installation is crucial to ensure that the wiring and components are set up correctly and safely.
- Maintain Your HVAC System: Regular maintenance is vital to preventing surge-related damage. This includes routinely cleaning or replacing air filters, monitoring refrigerant levels, and examining electrical connections to ensure they are secure and in good condition.
- Consider a Whole-House Surge Protector: A whole-house surge protector is an excellent investment for extensive protection. Installed at your home’s main electrical panel, this device guards all your appliances, including the HVAC system, against power surges. It provides a blanket of security that helps keep your entire electrical infrastructure safe.
Warranty and Insurance Considerations for HVAC Surge Damage
It’s important to note that the warranties provided by HVAC manufacturers typically exclude coverage for damage caused by power surges. While homeowners’ insurance may offer some recourse, proving claims for surge damage can be difficult, especially since the damage can accumulate over time. Consequently, you might find yourself responsible for expensive repairs resulting from scenarios like lightning strikes, overloaded electrical circuits, or issues with your appliances.
