Should I Choose a Generac or KOHLER Home Backup Generator?
Published October 14, 2026 2 views
Quick Answer
Choosing between Generac and KOHLER depends on your specific household needs, budget, and power requirements. Generac is a market leader known for its extensive service network, user-friendly mobile monitoring, and a wide range of models suited for various residential sizes. KOHLER is frequently recognized for its robust build quality, premium enclosures that resist harsh weather, and industrial-grade reliability. Both brands are highly reputable and offer dependable automatic backup power for residents in Passaic County. When deciding, consider the availability of authorized local technicians for maintenance and warranty support. Ultimately, the best choice is often guided by a professional load calculation of your home's electrical demands to ensure your generator provides consistent, safe power during an outage.
Understanding Standby Generators
A residential standby generator is a permanent backup system that monitors utility power and activates automatically when an outage occurs. Unlike portable units, these systems run on your home’s existing natural gas or liquid propane supply, eliminating the need for manual refueling.
Sizing and Capacity
Proper sizing is the most critical step. We perform a load calculation to determine how many appliances—such as HVAC systems, refrigerators, and lighting—can be supported by the generator. Oversizing can lead to unnecessary fuel consumption, while undersizing may cause the unit to shut down under heavy load.
Fuel Considerations
Most installations in Passaic County utilize natural gas. However, if natural gas is unavailable at your property, liquid propane is a common alternative. We verify that your gas meter and piping system can accommodate the required BTU demand of the generator to ensure it performs at its rated capacity.
Installation and Code Compliance
Installing a standby generator is a complex project requiring proper electrical and gas permits.
- Automatic Transfer Switch (ATS): This component senses the utility power loss, disconnects your home from the grid, and connects it to the generator. It prevents the dangerous practice of backfeeding, which can harm utility workers.
- Placement and Setbacks: We must adhere to manufacturer guidelines and local municipal zoning ordinances regarding placement, including clearances from windows, doors, and combustible materials.
- Electrical Panels: Depending on your electrical service, we may perform a managed installation that prioritizes essential circuits to ensure efficient power distribution.
Maintenance and Reliability
Regardless of the brand, consistent maintenance is essential. This includes regular oil changes, filter replacements, and checking the battery and electrical connections. Whether you choose Generac or KOHLER, scheduling annual service with a professional ensures your system is ready to function when the power grid fails.
