Panel-mounted surge protective devices that defend every circuit in your home from lightning, utility grid events, and internal voltage spikes. Up to $50,000 connected equipment warranty.
Central Texas storms produce voltage transients that degrade electronics over time. A whole-home SPD (surge protective device) protects every circuit at the panel for a fraction of the cost of replacing damaged appliances.
Mounts directly in your main panel. Protects every circuit downstream. Square D Surgebreaker, Eaton CHSPT2ULTRA, and Siemens FirstSurge are our standard installations. $450–$700 installed.
Installed at the meter base, before your main panel. Provides primary protection against utility-side surges. Required by some insurance carriers. $700–$1,100 installed including meter coordination.
Outlet-level surge protectors at sensitive equipment (computers, AV racks, medical devices). Layered defense after Type 1 and Type 2 catch the bulk of surges.
Most Square D Surgebreakers include up to $50,000 connected equipment warranty. Some homeowners insurance carriers offer policy discounts for installed SPDs.
Lightning strikes — about 5% of damaging surges. Direct strikes are catastrophic. Nearby strikes (within a few hundred yards) induce surges through the utility lines and can reach your panel.
Utility grid events — about 35% of damaging surges. Substation switching, downed line restoration, and grid imbalances send transients down the lines into your home.
Internal sources — about 60% of damaging surges. Large motor start-ups (AC compressor, well pump, refrigerator), microwave magnetron, and even hair dryer use create transient spikes that compound damage to electronics over time.
A whole-home SPD plus point-of-use protectors at sensitive equipment is the gold standard. The cost ($500-$1,200) is less than replacing a single high-end TV, computer, or smart appliance after a surge takes them out.
