Protect your panel, appliances, HVAC, EV charger, and electronics from Texas lightning and grid surges. Type 1 & Type 2 surge protective devices installed at your panel by licensed Master Electricians — for homes and businesses across the Austin area since 1997.
A power surge is a sudden spike of voltage pushed through your wiring — and it doesn't take a direct lightning strike to do damage. Most surges come from inside the grid: utility switching, downed lines, transformer faults, and even large appliances like your AC compressor cycling on and off. Central Texas gets more than its share of thunderstorms and grid strain, and every spike puts your electronics, appliances, and HVAC in the line of fire.
A whole-home surge protector — also called a whole-house surge protector or surge protective device (SPD) — is installed right at your electrical panel that clamps those voltage spikes before they reach your circuits. It's the difference between protecting a power strip's worth of gear and protecting everything hard-wired in your home — your HVAC system, EV charger, refrigerator, oven, well pump, smart-home equipment, and every outlet in the house. As of the 2023 National Electrical Code (Section 230.67), surge protection is now required on dwelling units, including whenever a home's service panel is replaced — so if you're upgrading your panel, this is the moment to do it right.

Straight answers to what Austin homeowners ask us most about surge protector installation.
If you have anything electronic worth protecting — HVAC, appliances, an EV charger, computers, or smart-home gear — yes. Most homes see dozens of small surges a month, and roughly 80% of them come from inside the house (large appliances cycling on and off), not just lightning. A single big surge can destroy thousands of dollars of equipment. A whole-house surge protector is inexpensive insurance by comparison.
Most whole-house surge protector installations run in the low hundreds of dollars installed — the exact price depends on your panel, the device rating, and whether any grounding or panel work is needed. We give you an upfront, no-obligation estimate before we start, so there are no surprises.
Yes. The National Electrical Code has required surge protective devices on dwelling units since the 2020 edition (Section 230.67), and the 2023 code carries it forward — including whenever a home's service equipment or panel is replaced. If you're upgrading your panel, surge protection is now part of a code-compliant job.
A plug-in power strip only protects what's plugged into it. A whole-house surge protector is wired into your electrical panel, so it protects everything in the home — including hard-wired equipment like your AC, oven, well pump, and EV charger that can't plug into a strip. The two work best together: panel-level protection first, point-of-use protectors for your most sensitive electronics.
A whole-house surge protector greatly reduces damage from nearby strikes and grid surges by diverting excess voltage away from your circuits. No device can absorb a direct lightning strike, but proper panel-level protection — combined with good grounding and bonding, which we always verify — is your strongest, code-recognized defense.
