WHOLE-HOME
SURGE PROTECTION
Protect every appliance and device in your home from power surges. Panel-level installation throughout Maryland and Washington DC. One surge can destroy thousands of dollars of electronics in an instant.
Why Whole-Home Surge Protection Matters
A single power surge can destroy thousands of dollars of electronics instantly. HVAC systems, refrigerators, televisions, computers, and smart home devices are all vulnerable. In Maryland and DC, where thunderstorms are frequent and power grid fluctuations are common, whole-home surge protection is one of the most cost-effective investments a homeowner can make.
Point-of-use surge protectors, the kind you plug into the wall, protect only what is plugged directly into them and wear out over time without any visible indication. A whole-home surge protector installed at the main electrical panel intercepts surges before they reach any device in the house.
Installation typically takes under two hours and the equipment carries a manufacturer warranty.
When You Need Surge Protection
- Maryland or DC home that experiences frequent thunderstorms
- Had power surges that damaged appliances or electronics in the past
- Home office with computers, servers, or networking equipment
- Recently installed a new HVAC system, EV charger, or major appliances
- Smart home devices, home theater, or high-end audio-video equipment
- Building or renovating and want surge protection installed as part of the project
- Current point-of-use surge protectors are several years old
Protection Options
Whole-Home Surge Protector
Installed at or near the main electrical panel. Intercepts voltage spikes before they travel through your home's wiring. Protects every outlet and hardwired appliance in the house.
Panel-Level Surge Protector
Higher-capacity device mounted directly inside the panel. Recommended for homes with significant electronics investments, home offices, or properties where equipment downtime is costly.
Point-of-Use Combined Protection
A whole-home or panel-level device handles major surges at the panel, and point-of-use suppressors at sensitive devices provide a second layer of protection for computers and audio-video equipment.
Sub-Panel Surge Protection
For detached garages, workshops, or outbuildings with their own sub-panel. Protects equipment in those spaces independently.
Commercial Surge Protection
Commercial-grade devices rated for higher service amperages and more demanding equipment environments for light commercial properties in Maryland and DC.

Frequently Asked Questions
Is a whole-home surge protector necessary if I already use power strips?
Power strip surge protectors offer limited, localized protection. They do not protect hardwired appliances like HVAC systems, refrigerators, dishwashers, or water heaters. They also degrade with each surge they absorb and give no indication when they have stopped working. A whole-home surge protector at the panel addresses every outlet and every hardwired device in the house.
What causes power surges?
Most power surges do not come from lightning. The majority are internal, caused by large appliances cycling on and off. Air conditioners, refrigerators, and HVAC systems draw significant power when they start up, and that fluctuation creates small surges constantly. Lightning strikes are dramatic but less common. External surges can also come from utility grid switching and downed power lines. A whole-home surge protector handles all of these.
How do I know if my electronics have been damaged by surges over time?
Surge damage is often gradual rather than sudden. Electronics that fail earlier than expected, appliances that behave erratically, or smart home devices that drop their connections frequently can all be signs of cumulative surge damage. The best approach is to install protection before damage occurs rather than waiting for a visible failure.
How long does installation take?
Most whole-home surge protection installations take between one and two hours. The device mounts at or inside the main panel, connects to a dedicated breaker, and is tested before we leave. There is typically a brief power interruption during installation. We confirm the interruption window with you in advance.
What is the difference between a whole-home and panel-level surge protector?
A standard whole-home surge protector is mounted near the panel and provides solid baseline protection for most residential applications. A panel-level device is installed directly inside the panel and is rated for higher surge currents. For homes with significant electronics, home offices, or properties in areas prone to utility fluctuations in the DC metro region, the panel-level device is the better choice.
