Frequently Asked Questions

Get answers to common questions about home standby generators, installation, and maintenance.

What is a home standby generator?

A home standby generator is a permanently installed backup power system that automatically turns on when utility power is lost. Unlike portable generators, standby units connect directly to your home's electrical panel and fuel supply (natural gas or propane), providing seamless, hands-free power restoration within seconds of an outage.

What size generator do I need?

Generator size depends on your home's electrical load. Small homes (1,000-1,500 sq ft) typically need 10-14kW, medium homes (1,500-2,500 sq ft) need 14-20kW, and larger homes may require 20-26kW or more. Key factors include the number and size of air conditioners, electric appliances, and whether you want essential-circuit or whole-house coverage. We carry units from 10kW to 150kW.

Natural gas vs propane: which is better?

Both fuels work excellently. Natural gas provides unlimited fuel supply (no tank refills) and is ideal if you have existing gas service. Propane offers slightly higher power output and works great in areas without natural gas. Most generators we sell are dual-fuel, allowing you to choose based on your situation.

How long does installation take?

Professional installation typically takes 1-2 days depending on complexity. This includes placing the generator on a concrete pad, connecting the transfer switch to your electrical panel, running fuel lines, and system testing. We recommend using a licensed electrician or authorized dealer for installation.

What maintenance is required?

Home standby generators require minimal maintenance. They automatically run weekly self-tests to stay ready. Annual service includes oil and filter changes, spark plug inspection, and battery check. Most manufacturers recommend professional maintenance every 200 hours of operation or annually, whichever comes first.

What is a transfer switch?

A transfer switch is the electrical component that safely disconnects your home from the utility grid and connects it to the generator during an outage. Automatic transfer switches (ATS) do this instantly without any action required. We offer transfer switches from 100 Amp for residential use up to 4000 Amp for large commercial applications.

Do you offer installation services?

We sell generators and transfer switches with nationwide delivery. For installation, we recommend working with a local licensed electrician or authorized dealer in your area. Many generator brands have dealer networks that can assist with professional installation and ongoing service.

What warranty coverage is included?

All generators we sell include the full manufacturer warranty. Generac, Kohler, and Cummins typically offer 5-year limited warranties. Briggs & Stratton leads the industry with a 7-year comprehensive warranty that covers parts, labor, and travel. Extended warranty options are available from most brands.
