Professional panel-mounted SPD installation with proper grounding verification. Protect your appliances, electronics, and HVAC before the next surge hits.
Most homeowners do not buy surge protection until after the surge.
That is a real pattern. The phone rings on a Monday morning, two days after the storm, and the call is about a refrigerator that stopped working, a microwave that came on but does not heat, an HVAC system that runs but does not cool, and a garage door opener that is now decorative. None of those failures looked like surge damage to the homeowner. They looked like equipment that died for no reason.
The surge protector that would have prevented most of it costs less than the cheapest item on that list.
This page is about installing the protection before the bill arrives, not after.
Type 2 SPD installed with shortest possible lead lengths, proper torque, and low Voltage Protection Rating (600V or lower). Status indicators included.
Additional Type 2 SPDs for detached garages, workshops, ADUs, and large additions where justified.
Type 3 surge suppressors for home theaters, servers, medical equipment, and high-value electronics.
Full grounding electrode system inspection and correction before SPD installation.
Surge protection does not announce itself. A whole-house surge protective device sits on the wall next to the panel, indicates green, and absorbs voltage transients silently for years.
The benefit shows up in things that did not happen: appliances that last longer, electronics that survive storms, HVAC equipment that runs longer between failures.
The dominant cause is cumulative: utility switching, neighbor HVAC cycling, motor inrush, and minor lightning activity. A whole-house SPD clamps the worst events and extends equipment life significantly.
