Most Popular Generac® Generators for Homeowners
The Guaranteed Lowest Rate On Installs Are In September
Generac Guardian 24kW
The Guardian 24kW delivers more power in the same compact footprint as smaller models, making it one of the most popular whole-home choices for Middle Tennessee families. With extra capacity beyond the 22kW, it’s perfect for larger homes, households with multiple HVAC systems, or anyone who wants to keep more circuits — like kitchens, laundry rooms, offices, and entertainment spaces running seamlessly.
Generac Guardian 26kW
The Guardian 26kW is the strongest air-cooled standby generator on the market — built for homeowners who want absolute assurance their lifestyle will continue uninterrupted during a power outage. With industry-leading capacity, it can handle estate-sized residences, multiple HVAC units, well pumps, workshops, or even future demands like EV charging stations.
Generac Guardian 22kW
The Generac Guardian 22kW is the best-selling standby generator in the country for good reason — it delivers the ideal balance of power, price, and performance. With enough capacity to cover nearly every circuit in a typical Middle Tennessee home, it easily handles larger appliances like central HVAC systems, well pumps, and refrigerators without hesitation. Compact yet powerful, it fits seamlessly alongside your home, runs quieter than most A/C units.
Generac Guardian 18kW
The Guardian 18kW is a smart entry point for homeowners who want reliable backup power at a lower cost. It’s sized to comfortably run the essentials — kitchen appliances, lighting, sump or well pumps, and a heating or cooling system, while using advanced load management to stretch performance further. Compact in footprint and quieter than most central air units, the 18kW blends into your property without being intrusive.
