Whole house surge protection Houston homeowners rely on is essential during storm season to keep appliances, HVAC, and smart devices safe from damaging voltage spikes. If you’ve ever lost a TV, fridge board, garage door opener, or Wi-Fi gear after a storm, you already know the pain. The smartest defense? Whole house surge protection—installed at your main electrical service—so voltage spikes never make it to your appliances in the first place.

Lightning strikes, grid switching, and utility hiccups send voltage spikes through your home’s wiring.

Even a single surge can destroy costly electronics (HVAC control boards, refrigerators, TVs, gaming consoles, smart devices). Smaller “everyday” surges slowly weaken components, leading to random failures months later—right when you least expect (and need) them.

A professionally installed whole house surge protector stops those spikes at the panel, protecting every circuit and outlet at once. Pair it with point-of-use protectors for layered safety.

What Causes Power Surges in Houston?

Lightning and Gulf storms during hurricane season
Utility grid switching and neighborhood outages/restorations
Large appliance cycling (A/C compressors, pool pumps) creating internal surges
Downed lines or transformer issues after high winds

Surge protectors are not just for “big strikes.” Micro-surges add up—quietly damaging electronics over time.

Whole House vs. Power Strips: What’s the Difference?

Power strips (with MOVs) protect only what’s plugged into them—and only that outlet.
Whole house surge protection mounts at your electrical panel and shields every circuit (kitchen, laundry, home office, smart devices, garage, outdoor equipment).

For best results, use both: whole house protection at the panel + quality point-of-use protectors for sensitive electronics.

What a Whole House Surge Protector Actually Does

A whole house SPD (Surge Protective Device) monitors incoming voltage and diverts dangerous spikes to ground in milliseconds—before they reach your appliances. Benefits include:

Protection for HVAC systems, refrigerators, washers/dryers, ovens, microwaves
Coverage for computers, TVs, game consoles, mesh Wi-Fi, smart home devices
Longer lifespan for electronics (less “mystery” breakdowns)
Peace of mind during Houston’s stormy months

Signs You Need Whole House Surge Protection

You’ve replaced a control board or motherboard in HVAC/refrigerator/garage door opener
Frequent breaker trips or flickering lights during storms
You rely on home office gear (modem, router, NAS, desktop)
You’ve invested in smart home solutions and can’t risk downtime
You use pool equipment (pumps, heaters) that’s surge-sensitive

The Smart Choice Installation Process

Safety inspection of your panel and grounding/bonding
Right-sizing the SPD for your panel and loads
Clean, code-compliant install at the service equipment (short lead lengths for performance)
Labeling, testing, and homeowner walkthrough (LED indicators, replacement guidance)

Good to Know: Panel Health & Surge Protection

Surge protection works best when your electrical system is in good shape. If your panel is outdated, overloaded, or has recalled breakers, consider a panel upgrade at the same time as your surge install for maximum safety and reliability.

Frequently Asked Questions

Do I still need power strips?
Yes—use them for ultra-sensitive devices. Think of it as layered protection: whole house at the panel + point-of-use at the outlet.

Will the SPD stop lightning completely?
No device can guarantee 100% lightning elimination, but a properly installed whole house SPD dramatically reduces surge energy entering your home.

What about warranty/indicator lights?
Quality SPDs include status LEDs. If the unit ever sacrifices itself during a major event, we’ll advise on replacement. Ask about manufacturer warranties.

Is maintenance required?
We recommend a quick visual check of the indicator lights a few times per year, and a professional check during your routine electrical inspection.
