Understanding Costco's Whole-Home Generator Installation Service

Costco has long been a trusted retail giant in the United States, and now, in 2026, they are stepping into the utilities market offering whole-home generator installation services for their members. As homeowners across the country seek reliable energy solutions amidst increasing weather-related power outages, this service is both timely and significant. This article explores the essential details of this service, addressing common questions and providing actionable insights for potential users.

What Exactly Is a Whole-Home Generator?

A whole-home generator is an automatic backup power solution that can keep your entire home running in the event of a power outage. Unlike portable generators, these systems are permanently installed outside your home, similar to a central air conditioning unit. They run on natural gas or liquid propane (LP) fuel and can power nearly every aspect of your home, depending on the size and capacity.

Convenience: Automatically turns on within seconds of a power outage.
Capacity: Capable of supplying power to multiple large appliances and systems.
Duration: Can run for days provided they have sufficient fuel supply.
