How to Choose Whole House Generators
Power Output
Look for a generator with enough wattage for your home. For most homes, a generator with at least 10,000 watts will cover essential appliances. Check the starting and running wattage. Starting wattage is typically higher than running wattage.
Fuel Type
Generators can run on gasoline, propane, or natural gas. Dual-fuel options give you flexibility. If you want longer run times and cleaner emissions, consider propane or natural gas.
Automatic Start Feature
Choose a generator with an automatic start feature. This will allow it to power on during outages without your help. Look for models with a reliable transfer switch to enable a smooth switch.
Noise Level
Check the noise level rating for the generator. Generators can be loud, so look for models that operate below 60 decibels for quieter performance. This is especially important if you live close to neighbors.
Size and Weight
Consider the size and weight of the generator. Ensure that you have enough space for it and that it’s easy to move if necessary. Portable generators are often lighter, while whole house models can be heavier.
