Whole-Home Surge Protection in Longmont, Colorado

Longmont homeowners and businesses count on Three Crowns Electric for whole-home surge protection. We've been serving Boulder County since 2002 — our trucks are on Longmont streets every week, from Old Town Longmont and Prospect New Town to the neighborhoods that need us most.

Type 2 whole-home surge protective devices installed at the main panel to protect HVAC equipment, smart home systems, home office electronics, TVs, appliances, and anything else plugged into the house from lightning strikes and utility-side voltage spikes. The Front Range gets more lightning than almost any other part of Colorado, and whole-home surge protection is affordable insurance.

We cover every Longmont neighborhood — Old Town Longmont, Prospect, Mountain Brook, Southmoor Park — and zip codes 80501, 80503, 80504. Whether you're in a 1970s ranch or a brand-new build, the scope is the same: diagnosis first, written quote second, work starts only when you say go.

Frequently Asked Questions

Common questions about Surge Protection in Longmont.

Do the surge strips I have throughout my house do the same thing?

No. Point-of-use surge strips catch small spikes but they can't handle a real lightning-induced surge — those voltages and currents blow right through them. A whole-home Type 2 device at the main panel catches the spike upstream of everything, so your plug-in strips have a much easier job.

How much does whole-home surge protection cost?

Typical range is $300 to $800 installed, including the device itself, a dedicated breaker, and labor. A single mid-grade Type 2 unit from a manufacturer like Siemens, Eaton, or Square D with a decent joule rating and a visible status light is usually the right call for a Northern Colorado home.

Does this replace the surge protection in my AC unit or electronics?

No — layered protection is better. A Type 2 at the panel is your first line, catching the biggest hits. Point-of-use strips and built-in protection in your AC, TV, or computer handle what gets past. Together they catch almost everything. Alone, neither is enough.

How long does a surge protector last?

Most Type 2 devices have a status LED that tells you when the device has absorbed too many surges and needs replacement — usually after a handful of direct hits or several years of service. We install units with a visible status light so you can check it during annual walkarounds.
