We excluded any generators lacking safety features, such as automatic shut-off. Models with low power output for whole house use were also removed. Reliability and user reviews played a major role in this decision.
What we did not do
No products were tested hands-on. We did not take any lab measurements or create subjective scores. Our focus was on data collection and analysis to offer an informed guide.
How often this page is updated
This page will be updated every 3 months or as new models enter the market. We track changes in specifications and user reviews to ensure the information stays current.
What to look for
Power Output
Power output is important for a whole house generator. Look for models with at least 12,000 watts for adequate coverage. This ensures you can run essential appliances during an outage. Higher wattage models are ideal for larger homes.
Fuel Type
Generators can run on gasoline, propane, or natural gas. Some models are dual fuel, allowing you to choose between fuels for convenience. Propane generally burns cleaner and can be stored longer than gasoline.
Automatic Transfer Switch
An automatic transfer switch is essential for smooth operation. This feature detects when the power goes out and automatically starts the generator. It also switches the power source back when utilities are restored.
Noise Level
Noise level is an important factor to consider. Look for generators with noise ratings below 70 dB for quieter operation. This is especially important if you live in a suburban area or near neighbors.
Warranty and Support
A good warranty and customer support can save you time and money. Check if the manufacturer offers a long warranty period. Reliable customer service is essential for troubleshooting and repairs.
How to Choose Whole House Generators
Identify Your Power Needs
Start by calculating the wattage of the appliances you want to run. A whole house generator should have at least 12,000 watts for a medium-sized home. This ensures you can power essential systems during outages.
Offer of Automatic Transfer Switch
Choose a generator that includes an automatic transfer switch. This switch makes it easier to use the generator without manual setup. It will automatically start and switch power during an outage.
Consider Fuel Types
Select a generator based on your preferred fuel type. Gasoline is common, but propane offers cleaner burns. Dual-fuel options provide flexibility for different situations.
Check Noise Levels
Look for generators with noise levels below 70 dB for quieter operation. This is important if you want to avoid disturbing your family or neighbors during outages.
Review Warranty Options
A good warranty can protect your investment. Look for models with at least a 3-year warranty. This shows the manufacturer stands behind their product.
