Key variables to cost

Every home is different, and so is every installation. These items often vary widely and will heavily influence cost:

• The generator size (kW) required to meet the home's power needs
• The landscaping and trenching depending on the placement of the generator on the property
• The amount of materials required
• Preparatory gas and electrical upgrades
• Additional supporting system equipment
• Required permits

All these factors make estimating installation costs unique. Average install costs (not including the generator) range from $5,000 - $10,000. Generac offers an in-home consultation program that connects homeowners with certified dealers who are experienced in identifying and assessing these factors.

Free assessment from an Independent Authorized Service Dealer (IASD)

The best way to know for sure is to get a free in-home assessment. Certified service dealers will ask questions to determine needs, assess the home's requirements, and provide a detailed quote. In-home assessments are not charged and homeowners are not pressured or obligated to follow through with an installation.

Sourcing a generator

Generators can be sourced through a variety of channels, including online, retail locations such as Lowes, Costco, Home Depot, or directly through authorized dealers. 

Solution Finder

Use the interactive Solution Finder to understand how the amount of power you want to use during a power outage impacts the range of power you’ll need in a generator.  To learn more about the right standby generator setup for your home and specific needs, welcome a local Authorized Dealer to your home for a free in-home assessment.
