Randy and I talk with homeowners across Queen Creek, Scottsdale and the rest of the East Valley every week, and the same question keeps coming up: “What’s one thing I can do to make my home safer?” Our answer usually starts with surge protection. Here are five upgrades we recommend, beginning with the one that protects everything else.
Short answer: A whole-home surge protector is installed at your electrical panel and limits voltage spikes from lightning, grid switching and large appliances before they reach your wiring and devices. It works best paired with plug-in surge strips for electronics. Along with an inspection, LED lighting, smart controls and planning for new loads, it’s one of the most practical safety upgrades.
1. Why install a whole-home surge protector?
Monsoon lightning, utility switching and storm-related outages can all send brief voltage spikes through your wiring. Inside the home, large motors like AC compressors and pool pumps can create smaller surges every time they cycle. Over time, those spikes can damage the electronics in TVs, computers, refrigerators, HVAC controls, garage door openers and smart devices.
Plug-in surge strips protect only what’s plugged into them. A whole-home surge protector is mounted at or next to your main panel, so it helps protect every circuit in the house, including hardwired equipment like your AC, pool equipment and appliances.
How does a whole-home surge protector work?
It watches the voltage on your electrical service. When a spike comes in, it diverts the extra energy to ground before it can travel through your circuits. Most units have indicator lights that show whether the protection is still working.
Does it replace surge strips?
No. Think of it as layers. The panel unit handles large surges from outside, and good surge strips at your TV and computer catch what’s left. No surge device can stop a direct lightning strike to your home, but layered protection greatly reduces everyday risk.
Is surge protection required by code?
The current electrical code requires whole-home surge protection when a home’s electrical service is installed or replaced, so we include it on every job that touches the panel and recommend it for every home. Code editions are adopted by each city or county, and your electrician will know the local requirement.
Many homeowners add surge protection during a panel upgrade or an electrical panel inspection. Installation means working inside the panel, and sometimes coordinating with SRP or APS, so it’s a job for a licensed electrician.
2. When should I schedule an electrical safety inspection?
Many hazards, like loose connections, overloaded circuits or a worn-out panel, aren’t visible from the outside. Arizona heat and monsoon storms put extra stress on electrical parts. A home electrical inspection is worth scheduling when you buy a home, before a remodel or a big new load, in an older home, or after storm damage. Randy checks the panel, outlets, GFCIs and grounding, then explains what he finds in plain language.
3. Is it worth switching to LED lighting?
Yes. LEDs use much less energy than incandescent bulbs, last far longer and run cooler, which matters in hot Arizona attics and enclosed fixtures. Today’s LEDs come in warm, dimmable and color-tunable options, so you don’t have to give up good light. Recessed LEDs remove countertop shadows in kitchens, and layered lighting adds depth to living spaces. Our lighting installation team can help you plan fixtures, not just bulbs.
One tip: if your LEDs flicker or buzz on a dimmer, the dimmer may not be compatible. That’s an easy fix for an electrician.
4. Do smart lighting controls and devices save energy?
They can. Smart thermostats can adjust the temperature when you’re away, and smart lighting lets you turn off forgotten lights from your phone, set schedules and create vacation modes. Smart switches and dimmers need proper wiring and, in many cases, a neutral wire in the switch box, so they’re best installed by an electrician. See our lighting controls page and our post on smart home electrical trends for ideas.
5. How do I prepare my electrical system for future needs?
EV chargers, induction cooktops, heat pump water heaters, pools, spas, casitas and home offices all add load. Even if those projects are a year or two away, it helps to know whether your panel has room. Randy can do a load calculation and tell you whether you need a panel upgrade, a subpanel or just a new circuit. For an EV charger on a tight panel, he usually recommends a power-monitoring, load-managing charger first. If an EV is on your list, start with our guide on EV charger installation and our post on future-proofing your electrical system.
Home safety upgrade checklist
- Add a whole-home surge protector at your panel (we recommend it for every home)
- Use quality surge strips for TVs, computers and gaming systems
- Schedule an electrical inspection if you’ve bought, remodeled or had storm damage
- Replace remaining incandescent bulbs with LEDs
- Check that dimmers are LED-compatible
- Plan smart switches and controls with an electrician
- Find out whether your panel has room for future loads
When should I call an electrician?
Call us if breakers trip often, lights flicker when the AC starts, an outlet feels warm or buzzes, or you notice a burning smell. If you see sparks or smoke, stop using that outlet or appliance and keep everyone away. Turn off the breaker only if you can reach it safely and the area is dry, and call 911 if there’s smoke or fire. Never open your panel to check a surge protector yourself. We answer emergency calls 24/7.

Frequently asked questions
What does a whole-home surge protector do?
It’s installed at your electrical panel and diverts voltage spikes to ground before they travel through your circuits. That helps protect hardwired equipment like your AC and appliances, plus everything plugged into your outlets.
Do I still need surge strips with whole-home surge protection?
Yes. Use quality surge strips for sensitive electronics like TVs and computers. The panel unit handles larger surges, and the strips add a second layer of protection.
Can a whole-home surge protector stop lightning damage?
No surge device can stop a direct lightning strike. Whole-home surge protection limits the much more common surges from nearby strikes, utility switching and large appliances.
Is surge protection required when I upgrade my panel?
Yes. The current electrical code requires whole-home surge protection when a home’s service is installed or replaced, so we include it on every job that touches the panel and recommend it for every home. Your electrician will know the local requirement.
Can I install a whole-home surge protector myself?
No. It’s installed inside or beside your electrical panel, which has parts that stay energized even with the main breaker off. Have a licensed electrician install it.
How do I know if my surge protector is still working?
Most whole-home units have indicator lights. If a light shows the protection is used up, or after a major storm, call an electrician to check it. Don’t open the panel yourself.
