Most of us don’t think about our home’s electrical system until something stops working. The air conditioner won’t start after a storm, the refrigerator’s control board is fried, or the TV never turns back on.
Often the culprit is a power surge, a split-second spike in voltage you never see coming. For homeowners in Georgetown and Sun City Texas, a whole home surge protector is one of the simplest, most practical upgrades you can make. Here’s a plain-English guide to what surges are, why they matter in Williamson County, and what to expect when a licensed electrician installs one.
What Is a Power Surge?
A power surge is a brief jump in voltage above the level your home’s wiring is designed to carry. It may last only a fraction of a second, but that’s enough to stress the sensitive circuit boards found in nearly every modern appliance. Surges come from two directions.
External Surges
These start outside your home and travel in on the power lines. Common sources include nearby lightning (it doesn’t have to hit your house), utility switching on the grid, and power being restored after an outage.
Internal Surges
Many surges start inside your own home. Motors and large loads, like your AC compressor, refrigerator, and pool pump, create small spikes as they cycle on and off. One small surge rarely causes visible damage, but repeated stress can wear electronics down over time.
Why Surge Protection Matters in Georgetown and Sun City
Our storms. According to Vaisala Xweather’s 2025 Annual Lightning Report, Texas recorded about 47 million lightning events in 2025, more than any other state. Part of that is our size, but anyone who has lived through a Central Texas spring knows how active our storms can be.
The cost. Insurance Information Institute data show Texas homeowners filed 4,188 lightning-related insurance claims in 2025, averaging $60,382 per claim, more than double the national average of $26,616. Those figures cover all types of lightning damage, not only surges, but they show what’s at stake.
The grid. Whether your power comes from Georgetown Utility Systems, Pedernales Electric Cooperative (PEC), or Oncor (all three serve parts of the Georgetown area), switching and restoration can send brief spikes down the line. Many neighbors remember the February 2021 winter storm, when Community Impact reported Georgetown residents going 12 hours or longer without power during rolling outages.
Our homes. Construction in Sun City began in 1995, and many established Georgetown homes were built before smart refrigerators, inverter-driven air conditioners, and home EV chargers were common. Today’s homes simply have more electronics worth protecting.
Why Power Strips Alone Aren’t Enough
Many people assume the strip behind the TV has them covered. Here’s the catch:
- A basic power strip is not a surge protector. Unless it’s specifically listed for surge protection, it just adds outlets.
- Plug-in surge protectors only protect what’s plugged into them. They can’t help your air conditioner, water heater, oven, or other hardwired equipment.
- They can’t stop a surge from traveling through your wiring to everything else in the house.
How a Whole-Home Surge Protector Works
A whole-home surge protector, also called a surge protective device (SPD), is installed at or right next to your main electrical panel. When a surge arrives, it limits the voltage by diverting the excess energy to ground, reducing how much reaches the circuits in your home.
Type 1 vs. Type 2
- Type 1 devices can be installed on the line side of the main breaker and are designed for surges coming in from the utility, such as lightning.
- Type 2 devices are installed on the load side of the main breaker, typically in or beside the panel, and help with residual lightning energy and surges generated inside the home.
The right choice depends on your panel, your service, and the manufacturer’s instructions. A qualified electrician will select a UL-listed device suited to your home.
What It Helps Protect
- HVAC systems, including control boards and inverter electronics
- Refrigerators, ovens, induction ranges, washers, and dryers
- EV chargers and garage door openers
- Pool equipment and electronic water heater controls
- Smart TVs, computers, routers, and home office equipment
- Smart thermostats, doorbells, and security systems
- GFCI and AFCI devices, smoke alarms, and other safety equipment
Layered Protection: The Smart Approach
The best protection works in layers:
1. At the panel: A whole-home SPD is your first line of defense for every circuit.
2. At sensitive equipment: Listed plug-in surge protectors add a second layer for TVs, computers, and home office gear.
3. On other incoming lines: Surges can also enter through cable, internet, or phone lines. Ask whether those connections need protection, too.
A Note for Sun City Residents
Sun City Texas has more than 9,000 homes and an estimated 17,000 residents, according to the Sun City Texas Community Association. For many households, the electronics that matter most are health and comfort essentials: oxygen concentrators, CPAP machines, lift chairs, adjustable beds, and medication refrigerators.
The FDA’s guide for people who use powered medical devices at home suggests asking your device manufacturer or medical provider whether a power surge could stop your device from working and, if so, what type of surge protector you need. Pair that advice with whole-home protection at the panel. And remember, surge protection is not backup power. If a device must keep running during an outage, ask your provider about battery backup.
Surge Protection Is Now Part of the Electrical Code
Beginning with the 2020 edition, National Electrical Code (NEC) Section 230.67 requires a Type 1 or Type 2 surge protective device for services supplying homes, including when service equipment is replaced. Texas adopted the 2023 NEC statewide in September 2023, and the City of Georgetown now lists the 2026 NEC among its adopted codes, which keeps this requirement in place.
If you’re planning an electrical panel upgrade or service replacement, surge protection will be part of the plan. If your home was built before these rules, adding an SPD brings it closer to today’s standard.
Why a Licensed Master Electrician Should Install It
Installing a whole-home surge protector means working inside your main electrical panel, so it is not a DIY project. The device must be compatible with your panel, wired correctly with solid grounding and bonding, and installed to manufacturer instructions and applicable code. A professional can also spot other issues, such as a worn panel or loose connections, while the cover is off.

4. Walkthrough: You learn what the status indicator lights mean and when to call.
Frequently Asked Questions
Is a whole home surge protector in Georgetown, TX worth it?
For most homes, yes. Central Texas sees frequent thunderstorms, and modern HVAC systems, appliances, and EV chargers rely on sensitive electronics. A whole-home surge protector adds a first layer of protection for hardwired equipment that plug-in strips can’t reach.
Will it stop a direct lightning strike?
No surge protector can guarantee protection from a direct strike. A whole-home SPD limits surges on your electrical circuits, including those from nearby lightning and utility switching. It reduces risk, but it is not a guarantee.
Do I still need plug-in surge protectors?
Yes, for sensitive electronics like TVs, computers, and medical devices. Whole-home and point-of-use protectors work together. Just make sure your plug-in units are listed surge protectors, not basic power strips.
How long does a whole-home surge protector last?
SPDs wear out over time and after absorbing large surges. Most have status indicator lights. Check them periodically and call an electrician if a light changes or goes out.
Can surge protection be added to an older Sun City home?
Often, yes. A home’s age alone doesn’t mean you need a new panel. An electrician will check your existing panel first and explain any needed repairs before you approve the work.
