Whole-home surge protection in Dallas
A surge protector at the panel guards AC boards, appliances and electronics from spikes.

Short answer: A whole-home surge protector mounts at your breaker panel and limits voltage spikes before they reach your circuits. It protects things you cannot plug into a power strip, like the AC control board, the fridge and the furnace.
Most surges are not lightning strikes. They come from the utility switching loads, from big motors in your own house cycling on and off, and from storms on the grid. Each surge wears down the electronics in modern appliances, HVAC boards and pool equipment.
A panel-mounted surge protective device is the first layer. Plug-in protectors at the TV and computer are the second. Together they cover the house, and the current code requires a surge device when a service is replaced or upgraded.
Whole-Home Surge Protection: signs to watch for

Typical installed surge protector
Includes the device and installation at an accessible panel.
Type 1 or Type 2
Type 1 surge devices can mount on the line side, ahead of the main breaker, and handle larger surges. Type 2 devices mount on the load side at a breaker in the panel and are the most common residential choice. Either one works best with short, straight leads and good grounding, which is why we check the grounding electrode system at the same time.
What moves the price
- Panel space for a two-pole breaker
- Type 1 versus Type 2 device
- Grounding repairs found on the same visit
Whole-Home Surge Protection in Dallas homes
North Texas gets a lot of lightning in spring and early summer, and the grid sees heavy switching on 100-degree days. A $3,000 heat pump with a fried control board is a common call after a storm week. A surge device at the panel costs much less than one board.

Questions people ask us
Will a surge protector stop a direct lightning strike?
Nothing stops a direct strike completely, but a panel surge device greatly reduces damage from nearby strikes and grid surges.
How long does a whole-home surge protector last?
Many last years, but each large surge uses up some capacity. Most have a status light that tells you when to replace it.
Do I still need power strips?
Yes. Point-of-use protectors at sensitive electronics add a second layer behind the panel device.
