Generac Generator FAQ
What is a Generac generator?
A Generac generator is a backup power system that automatically provides electricity to your home or business during an outage. Generac is one of the most trusted names in standby power, offering models for whole-house coverage or just essential circuits.
How does a Generac generator work?
Generac generators are permanently installed outside, similar to an AC unit. They connect to your home’s electrical panel and run on natural gas or propane. When the power goes out, the Generac generator automatically turns on within seconds and keeps running until utility power is restored.
What size Generac generator do I need?
The right size depends on what you want to power. Smaller Generac generators can run essentials like refrigerators, lights, and sump pumps, while larger units can power your entire home, including HVAC systems. A professional installer can calculate your electrical load and recommend the right model.
How long can a Generac generator run?
Generac generators can run for as long as you have a fuel supply. With natural gas, they can run indefinitely during an extended outage. With propane, run time depends on the size of your tank. Many homeowners keep enough fuel for at least several days of continuous power.
How often should a Generac generator be serviced?
Generac recommends servicing once a year or after every 200 hours of use. Routine maintenance includes oil and filter changes, battery checks, and system testing to make sure the generator is ready when you need it.
How loud is a Generac generator?
Most Generac standby generators run at around 65–70 decibels, similar to the sound of a central AC unit. Generac designs its generators with quiet operation in mind, especially for residential neighborhoods.
Does a Generac generator add value to my home?
Yes. Having a Generac standby generator can increase property value because it provides peace of mind and convenience. Potential buyers see it as a major upgrade, especially in areas where power outages are common.
What is the warranty on a Generac generator?
Most residential Generac generators come with a 5-year limited warranty. Extended warranties may also be available through authorized dealers or installers.
How much does a Generac generator cost?
The cost depends on the size and installation requirements. Smaller standby models can start around $5,000 installed, while whole-house Generac generators may range from $9,000–$15,000 or more. The best way to get an accurate price is through a free in-home or virtual consultation.
Can a Generac generator power my entire home?
Yes, many Generac models are designed for whole-house power. With the right size unit and an automatic transfer switch, you can keep everything in your home running — from lights and appliances to heating and cooling.
