What Summer Power Surges Can Do to Your HVAC System
Summer weather can put your HVAC system under significant strain, especially during periods of extreme heat, thunderstorms, and increased electricity demand. One issue homeowners may not immediately consider is the effect of power surges on air conditioners and other HVAC equipment. Even a brief electrical surge can potentially affect sensitive components and lead to unexpected cooling problems.
A power surge occurs when there is a sudden increase in electrical voltage. During the summer, surges may be associated with lightning, utility grid fluctuations, power outages, or electricity being restored after an outage. While some surges are noticeable, others may happen without any obvious signs.
How Power Surges Can Affect Your HVAC System
Modern HVAC systems contain several electrical and electronic components. A sudden voltage spike can place stress on parts such as capacitors, control boards, compressors, thermostats, and motors.
In some cases, a major surge may cause immediate equipment failure. Your air conditioner may stop running, fail to start, or begin behaving unpredictably. Smaller surges can be more difficult to identify because the system may continue operating while electrical components have experienced additional stress.
After a summer storm or power interruption, pay attention to changes in your HVAC system. Warning signs can include unusual noises, frequent cycling, difficulty starting, reduced cooling performance, a blank or malfunctioning thermostat, or circuit breakers that repeatedly trip.
What Should You Do After a Power Surge?
If your HVAC system is not operating normally after an outage or electrical event, avoid repeatedly resetting breakers or attempting complicated electrical repairs yourself. HVAC equipment combines high voltage electricity with mechanical components, making professional diagnosis the safer approach.
A qualified HVAC technician can inspect the system, test electrical components, identify damaged parts, and determine what repairs may be necessary.
Homeowners may also want to ask an HVAC professional about appropriate surge protection options. Protecting HVAC equipment from electrical fluctuations can provide an additional layer of protection for important system components.
