Portland summers are full of character. From surprise heatwaves to sudden storms, they often bring more than just warm days. But, alongside the rise in temperatures comes something less thrilling for homeowners—unexpected power surges.
Even a split-second power surge can wreak havoc on your home’s electronics and appliances. Think fried laptops, blinking clocks, or even major damage to your HVAC system.
Want to protect your home’s electronics and avoid costly replacements? This guide explains what causes summer power surges, what’s at risk, and how you can safeguard your home effectively.
What Causes Summer Power Surges?
Understanding the common triggers for power surges can help you take precautions before they cause harm. Here are a few key culprits, especially during Portland summers:
1. Lightning Strikes
Though relatively rare in the Pacific Northwest compared to other regions, summer thunderstorms can produce lightning that disrupts power grids. A single strike that hits the wrong spot can send a surge rippling through your lines in seconds.
2. Extreme Heat and Energy Demands
When heatwaves cause neighborhoods to crank up their air conditioning units, the sudden shifts in electricity usage can overload circuits or spark fluctuations in the power grid.
3. Grid Fluctuations in Aging Infrastructure
Many Portland neighborhoods still run on older electrical systems. Grid fluctuations or downed lines in these areas can create power surges as the system struggles to meet modern demands.
4. Appliance Cycling
Large appliances like HVAC systems, refrigerators, and washers naturally cycle on and off during use. These power-hungry devices can cause small, localized surges in your home’s electrical system.
What Can a Surge Damage?
The damage caused by power surges might surprise you. With homes increasingly relying on “smart” technology and high-value electronics, modern households are more vulnerable than ever.
Here’s a look at what’s at risk in your home:
1. Electronics
- Smart TVs
- Laptops and desktops
- Routers and modems
- Gaming systems
2. Appliances
- Refrigerators
- Microwaves
- Coffee makers
3. Home Systems
- HVAC systems
- Water heaters
- Washers and dryers
- LED lighting
- Security systems
Replacing damaged electronics and appliances can be costly—not to mention disruptive if those devices play a key role in running your home.
How to Tell If You’ve Experienced a Surge
Sometimes, power surges are so brief that they go unnoticed until it’s too late. However, there are some telltale signs to watch for:
- Blinking Clocks or Flickering Lights: Sudden disruptions to your power source can reset certain devices or cause your lights to dim.
- Shutdowns or Restarts: Your devices may unexpectedly power off or reboot.
- Buzzing or Burned-Out Electronics: That strange buzzing sound from your device could indicate internal damage caused by a surge.
- Tripped Breakers or Damaged Outlets: Higher-than-usual voltage can trip circuit breakers or even char outlets in severe cases.
If you notice any of these signs, it’s a good idea to evaluate your home’s electrical system.
How to Protect Your Home
Power surges might be unpredictable, but protecting your home doesn’t have to be complicated. Here are four effective strategies to minimize your risk:
1. Use Surge Protector Power Strips
This affordable solution is a must for sensitive electronics like computers, TVs, and office equipment. A surge protector adds an extra layer of defense, preventing smaller surges from damaging your devices.
2. Install a Whole-Home Surge Protector
For comprehensive protection, have a licensed electrician install a whole-home surge protector at your electrical panel. This device shields your entire home, ensuring major appliances and smaller electronics are safe.
3. Unplug During Storms or Vacations
If you know a storm is coming or you’ll be away from home for some time, unplug high-value or rarely used items. Taking these devices off the grid entirely is the simplest way to keep them safe.
4. Keep Your HVAC System Maintained
Faulty HVAC systems or systems that draw irregular power can trigger minor surges. Routine maintenance helps ensure your unit runs efficiently and safely, reducing the risk of electrical issues.
When to Call a Pro
Some power surge issues require more than DIY solutions. Here are a few situations where you should reach out to a professional electrician:
- Frequent Flickers or Tripped Breakers: These may indicate underlying electrical problems in your home.
- Appliance Malfunctions: If your appliances regularly act up post-surge, have them inspected for damage.
- Major Upgrades: Installing new appliances, solar systems, or generators? A pro can ensure your electrical system supports these additions safely.
- Whole-Home Surge Protection: To safeguard all electrical systems, work with a licensed electrician to install a surge protector designed for your home’s needs.
Keep Your Electronics Safe All Summer
Power surges may be unavoidable, but the damage they cause doesn’t have to be. By proactively protecting your home’s electronics and investing in professional solutions like whole-home surge protectors, you can enjoy Portland’s summer months without worry.
