Whole-House Surge Protection in Lawrenceville, GA
Georgia gets a lot of lightning, and the grid delivers plenty of smaller surges on its own. A panel-mounted surge protective device is inexpensive insurance for everything in your home that has a circuit board.
Most people picture a direct lightning strike, but the bigger threat is the steady stream of smaller transient surges — from utility switching, nearby strikes, and large motors like your AC compressor cycling on and off. Each one chips away at the electronics in your HVAC, appliances, TVs and computers.
How whole-house surge protection works
A surge protective device (SPD) installs at your main panel and clamps voltage spikes before they spread to your branch circuits, diverting the excess energy to ground in nanoseconds. It's your first layer of defense. Point-of-use protectors (power strips) at sensitive electronics are the second layer — you want both.
What it protects
- HVAC systems — the control boards are expensive and surge-sensitive
- Kitchen appliances, washers and dryers with electronic controls
- Water heaters, well pumps and pool equipment
- LED lighting and dimmers
- Home theater, computers, networking and smart-home hubs
- EV chargers and standby generator controls
- Garage door openers
Installation
For a modern panel with an open double-pole slot, installation takes under an hour: we mount the SPD, land it on a short dedicated breaker, and verify the indicator. Older or full panels may need a breaker added or a small load-center change first — often a good moment to talk about a panel evaluation.
Ratings that matter
We install UL 1449-listed Type 2 devices with a solid joule rating, a low let-through (clamping) voltage, and a status indicator or alarm so you know when the unit has taken enough hits to need replacement. Many carry a connected-equipment warranty from the manufacturer.

FAQ
Whole-House Surge Protection in Lawrenceville, GA — Questions
Is whole-house surge protection worth it?
For the cost, yes. A single surge event that takes out an HVAC control board or a refrigerator often costs more than the device and installation combined, and Georgia lightning season makes surges routine.
Do I still need power strips if I have a panel surge protector?
Yes. The panel device handles the large transients; plug-in protectors at computers, TVs and audio gear catch the smaller stuff that gets through and add a layer of protection.
How long does a surge protector last?
It depends on how many surges it absorbs. Quality units have an indicator light; when it changes or goes out, the device has done its job and should be replaced. Many last 5 to 10 years.
Can you add surge protection without upgrading my panel?
If your panel has space and is in good condition, yes - it is a quick add. If the panel is full or is a defective brand, we will discuss options.
