Professional Whole-House Surge Protection Services

Power surges are brief spikes in electrical voltage that can damage or destroy sensitive electronics, appliances, and HVAC equipment. While most people think of lightning as the primary cause, the majority of damaging surges actually originate from within the home — from large motors cycling on and off (HVAC compressors, refrigerators, washing machines) and from utility grid fluctuations. The average home experiences 20+ internal surges per day.

A whole-house surge protection device (SPD) is installed at the main electrical panel and protects every circuit in the home simultaneously. It works by diverting excess voltage to the ground wire before it can reach your equipment — absorbing the surge in microseconds. This protects everything from computers and TVs to smart thermostats, HVAC control boards, garage door openers, and any appliance with electronic components.

Plug-in surge protector strips only protect the devices plugged into them and have limited surge absorption capacity. A whole-house SPD provides a first layer of defense at the panel, and can be supplemented with point-of-use strips at sensitive equipment for maximum protection.

Installation is straightforward for a licensed electrician — the SPD is mounted on or near the main panel, connected to a dedicated 2-pole breaker, and bonded to the ground bus. The entire installation typically takes 1 to 2 hours. Quality whole-house SPDs have indicator lights showing protection status and include a warranty that covers connected equipment damage up to a specified dollar amount.
