Warmer days and blooming landscapes signal the arrival of spring, but the season also brings sudden storms that can cause power surges—putting your HVAC system at risk. A well-maintained system is your best defense against unexpected breakdowns when you need cooling the most.
At Mainstream Electric, Heating, Cooling & Plumbing, we’ve spent over 20 years helping Spokane homeowners safeguard their homes from electrical surprises and HVAC issues. Stay ahead of potential problems and avoid costly repairs with regular AC maintenance, so you can enjoy spring without a hitch.
How Spring Power Surges Impact Your HVAC System
Power surges happen when there’s a sudden spike in voltage, often caused by lightning strikes, fallen power lines, or the restoration of electricity after an outage. These jolts travel through your home’s electrical wiring and can overwhelm sensitive appliances, including your HVAC system.
HVAC systems are particularly at risk because they rely on delicate components like circuit boards, motors, and compressors. Even a single surge can cause immediate damage or gradually wear down your equipment, reducing its lifespan.
Recognizing the link between power surges and HVAC damage is key to addressing the issue and ensuring your system stays operational when you need it most.
Signs Your HVAC System Was Damaged by a Power Surge
If your HVAC system isn’t working after a power surge, there are clear warning signs to watch for. One of the most obvious is a system that won’t turn on at all, which likely means the electrical components were damaged.
Another indicator is warm air blowing out of the vents when your system is set to cool. This could point to a damaged compressor or an electrical issue. Strange noises like buzzing or grinding, unusual odors such as burning plastic, or frequent circuit breaker trips are also signs of trouble.
Don’t ignore these symptoms, as they may signal deeper damage that needs immediate attention.
Troubleshooting Your HVAC System After a Power Surge
Check Your Circuit Breakers
Start by inspecting your circuit breakers. Look in your home’s electrical panel for any switches in the “off” position. Reset the tripped breaker by flipping it back to “on.” If it trips again immediately, avoid forcing it back on. This could indicate a larger electrical issue that needs professional help.
Inspect Your Thermostat
Double-check your thermostat settings. Power surges can sometimes reset them to factory defaults or an unintended mode. Make sure the thermostat is set to the desired temperature and mode. If the screen is blank, check its power source or replace the batteries.
Look for Visible Damage
Take a closer look at your HVAC unit for any visible issues, such as burnt wires, melted fuses, or scorch marks. If you notice damage, avoid touching the unit and contact a technician right away.
Prioritize Safety
While basic troubleshooting can be helpful, safety should always come first. If you’re unsure about the problem or see signs of electrical damage, call an HVAC professional instead of attempting repairs yourself. Mishandling electrical issues can be dangerous and might worsen the damage.
Emergency Solutions for Power Loss and HVAC Failures
When power surges disrupt your home, being prepared can make all the difference. Backup generators can keep essential systems like your HVAC running during outages.
Whole-home surge protectors are another effective solution. Installed at your electrical panel, they guard your home against voltage spikes, protecting valuable appliances like your HVAC system. If your system has already failed, reaching out to an emergency service provider is a smart move. Mainstream offers 24/7 emergency services to quickly address HVAC failures and restore comfort to your home.
Focus on Your Circuit Breaker Panel
Your circuit breaker panel plays a significant role in protecting your home’s electrical system. An outdated or overloaded panel struggles to handle modern electrical demands, leaving your HVAC system vulnerable during a surge.
Upgrading to a modern panel can reduce risks and improve your home’s reliability. Newer panels distribute power more effectively and handle surges better. Mainstream offers professional upgrades and maintenance to ensure your panel meets your home’s needs.
Protecting Your Heat Pump
Heat pumps are especially sensitive to power surges because they rely heavily on electrical components. Installing a dedicated surge protector for your heat pump is a smart way to prevent damage.
Regular maintenance is also important for keeping your heat pump in good shape. Scheduling annual inspections with a professional technician ensures your system is ready to handle seasonal demands.
Preventing Future HVAC Problems
Taking steps now can save you from headaches later. Installing whole-home surge protection is one of the best ways to shield your HVAC system from voltage spikes.
Routine HVAC inspections are equally important. During these checkups, technicians can identify potential issues, clean your system, and prepare it for peak performance. Additionally, securing outdoor units with protective covers and clearing debris can prevent physical damage during storms.
When to Call a Professional
Some HVAC problems are too complex to fix on your own. If your system still isn’t working after basic troubleshooting, it’s time to call an expert. Attempting to repair electrical components without training can lead to safety risks and might void your warranty.
A licensed HVAC technician has the tools and experience to diagnose and fix your system efficiently. Acting quickly can prevent further damage and get your system back up and running.
