Whole-Home Surge Protection in Denver, CO

A whole-home surge protector — also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS) — is installed at the home's main electrical panel. When an abnormally high voltage event occurs on the power lines, the device intercepts the surge before it travels through your home's wiring. This provides protection for electrical equipment connected throughout the home, not just at a single outlet.

Yes — Colorado averages more than 500,000 cloud-to-ground lightning strikes per year, with the Front Range and foothills particularly active during summer thunderstorm season. Lightning-induced surges can travel through utility lines and damage equipment throughout a home. Beyond lightning, utility switching events, power restoration after outages, and internal surges from HVAC and large appliances also contribute to cumulative surge exposure.

Whole-home surge protection installation cost depends on the device selected, rating and configuration, and whether any related panel or grounding work is identified during the evaluation. A basic panel SPD installation is generally one of the less expensive electrical upgrades for the protection it provides. Call (720) 255-9702 for a project-specific estimate.

A panel-mounted SPD helps protect equipment against large external surges entering through the utility lines. However, it does not eliminate all surge risk: internal surges from motors starting and stopping within the home still travel on branch circuits, and very large events (such as a direct lightning strike to the service entrance) can overwhelm any protection device. A layered approach — panel SPD plus quality point-of-use surge protection at sensitive equipment locations — provides more comprehensive coverage.

Power strips and UPS devices provide point-of-use surge protection at specific locations. A whole-home panel SPD adds a first layer of protection that intercepts large surges before they reach any outlet in the home — protecting equipment that isn't plugged into a surge-protecting strip, including HVAC systems, built-in appliances, and any device on a standard outlet. The two types work best in combination rather than as either/or choices.

Most panel-mounted SPDs and point-of-use surge protectors have an indicator light showing their protection status. If this light is off or shows a 'fault' or 'unprotected' status, the device has been sacrificed protecting against a surge and needs replacement. After significant storm events, it's a good practice to check all surge protection devices to confirm they're still showing protected status.

No. A UPS provides backup battery power during an outage as well as surge protection. A surge protection device (SPD) only protects against voltage surges — it doesn't provide battery backup. For equipment where continued operation during a power outage is important (servers, medical devices), a UPS serves both functions. For general surge protection throughout the home, a panel SPD plus point-of-use devices is the typical approach.
