Buying Guide for Whole Home Generators and Installation
Choosing the right whole home generator involves several key considerations to ensure safety, power adequacy, and efficiency. Additionally, professional installation plays a vital role in maximizing generator performance and compliance with local codes.
Power Capacity and Home Requirements
Assess your household power needs to determine the appropriate wattage. Consider appliances, HVAC systems, medical devices, and lighting. Whole home generators typically range between 8kW and 24kW and must provide enough capacity to power essential and high-demand circuits.
Fuel Type and Availability
Generators run on gasoline, propane, natural gas, or dual fuel. Dual fuel models offer flexibility, while natural gas generators provide uninterrupted fuel supply if connected to a permanent gas line. Propane is ideal for clean burning and long-term storage, but fuel availability may vary regionally.
Transfer Switch Integration
The transfer switch automatically shifts power from the grid to the generator. Ensure it matches your generator’s amperage and supports whole house load transfer where needed. Some models come with transfer switches included, while others require purchase and installation separately.
Installation Considerations
Professional installation is recommended to comply with electrical codes and ensure proper placement, ventilation, and transfer switch wiring. Certified installers evaluate site conditions, local permits, and generator placement for optimal operation and safety.
Noise Levels and Operating Features
Generators vary in noise output from quiet inverter models (~52 dBA) to larger standby generators (~67 dBA). Consider neighborhood noise regulations and your household’s comfort. Features like remote monitoring and auto-testing enhance user convenience and maintenance oversight.
Warranty and Service Support
The warranty period can reflect manufacturer confidence. Long warranties and accessible service networks provide assurance of lasting reliability. Check for extended warranty offerings and local authorized service providers for maintenance convenience.
