Choosing the Right Generac Generator for Your Home
Choosing a standby generator should be based on the electrical loads you want the system to support rather than home size alone. Refrigeration, HVAC equipment, lighting, cooking appliances, well or sump pumps, and other electrical loads can all affect generator-sizing requirements.
Coolray can evaluate your home's electrical demand and discuss Generac generator options that fit your backup-power goals. Some homeowners may want to power selected essential circuits, while others may want broader whole-home coverage.
The final generator size should be determined through an electrical load assessment rather than assuming a specific kilowatt rating is appropriate for every home of a certain size.
Not sure which generator is right for your home? You’re not alone. Here’s a quick breakdown to help you choose between two of the most popular whole-home options:
22kW: Solid choice for most medium to large homes. Keeps the essentials running—like your fridge, lights, sump pump, and even your central AC.
If you want to stay comfortable and connected during an outage without powering every single appliance.
24kW: Perfect for larger homes or families with higher energy needs. Think multiple HVAC systems, electric ovens, laundry machines, and more.
If you want your home to run almost like normal during an outage, this is the way to go.

Generac Generator FAQs
How do I know what size generator my home needs?
Generator sizing depends on which appliances, HVAC equipment, circuits, and other electrical loads you want powered during an outage. A professional load assessment can help determine an appropriate generator capacity.
How does a whole-home generator turn on during an outage?
A standby generator works with an automatic transfer switch. When utility power is lost, the system detects the outage and transfers designated electrical loads to generator power.
Where can a standby generator be installed?
Generator placement depends on manufacturer requirements, property layout, fuel connections, electrical access, and applicable codes.
Does a Generac generator require maintenance?
Yes. Standby generators require periodic maintenance to check oil, filters, spark plugs, electrical connections, the transfer switch, and overall system operation.
Can Coolray maintain a generator after installation?
Yes. Coolray provides maintenance for air-cooled generators, including inspection and routine service items.
