What Affects the Cost of a Generac Generator?
The cost of a Generac generator isn’t just about the equipment. It’s about delivering consistent, automated power tailored to your home’s specific needs. Several key factors influence the total installed price:
- Size and capacity – how much of your home you want to back up
- Fuel type – natural gas or propane generator setup
- Installation of a Generac power transfer switch
- Distance to gas lines and electrical panel
- Site preparation, permitting, and any required upgrades

Why a Whole House Generator Beats a Portable
A portable generator might seem like a convenient, less expensive fix. But when it comes to safety, reliability, and ease of use, a Generac whole house generator offers significant advantages:
Safety: The American Red Cross recommends permanently installed generators as a safer alternative to portables, which pose a greater risk of carbon monoxide poisoning if used improperly.
Convenience: Whole house systems start automatically within seconds of an outage. No hauling equipment, refueling, or running extension cords through your home.
Efficiency: These units run on your home’s natural gas or propane supply, which is typically less expensive than gasoline and doesn’t need to be manually refilled.
Hands-off operation: Whether you’re home or away, a standby generator turns itself on during an outage and off when utility power returns.
Full-home coverage – Depending on the size of your unit, it can power everything from your lights and appliances to your furnace, internet, sump pump, and more.
A properly installed Generac standby system is built to protect your entire home, safely and automatically, day or night.
Why the Cost Is Worth It
So, how much does a Generac generator cost you ask? Maybe a better question is: what does it cost not to have one? In Colorado, power outages are often more than just inconvenient. They can be very expensive. Spoiled groceries, frozen pipes that can burst and flood basements, lost work hours, and heating or cooling failures can all add up fast.
A Generac generator keeps your home running automatically: quietly, safely, and without you lifting a finger. It’s not just about comfort, it’s about protection and reliability.
