Why Henderson Homes Need Whole-Home Backup Power

Southern Nevada's grid gets pushed to its limits every summer. Between triple-digit heat waves driving peak AC demand and monsoon storms that can knock out lines with little warning, Henderson homeowners lose power at exactly the times it matters most — when AC failure isn't just uncomfortable, it's a real health risk for anyone elderly, very young, or medically vulnerable in the house.

A properly sized whole-home standby generator keeps your air conditioning, refrigerator, well or sump pump, garage door, and medical equipment running automatically, with no manual intervention required.

FAQ

Whole-Home Generator Installation Questions

How long does the whole process take, start to finish?

Typically 2-4 weeks from your first call to a finished, inspected install — the on-site work itself is usually 1-2 days, with the rest of the timeline being permit approval and equipment delivery.

Will a whole-home generator run my entire house, including AC?

Yes, if sized correctly for whole-house coverage (typically 17kW or larger for a Henderson home with central AC). We confirm exact sizing during your free assessment based on your actual panel and equipment.

Does the generator turn on automatically, or do I have to start it?

Automatically. The transfer switch detects a power loss and starts the generator within seconds — you don't need to be home or do anything.

What brands do you install?

We install Generac, Kohler, and Briggs & Stratton standby systems, and can walk you through the tradeoffs between them for your specific home and budget.
