How to Choose Whole House Generators
Power Output
Select a generator with enough watts to power your entire home. For a house with essential appliances, look for at least 5,000 to 10,000 running watts. Larger homes may need 20,000 running watts or more.
Fuel Type
Choose a generator that uses the fuel type most accessible to you. Gasoline is common, but propane or natural gas may be more efficient. Some generators offer tri-fuel capabilities for added flexibility.
Automatic Start
Consider a generator with an automatic start feature. This ensures it powers on during an outage without your intervention. Look for models that can detect power loss to activate automatically.
Noise Level
Check the noise level in decibels (dB). A quieter generator operates at around 60 dB. This is just above a normal conversation, which is preferable for residential use.
Portability Features
For portable generators, look for wheels and handles for easy transport. Some weigh less than 100 pounds, making them easier to move around. Consider how frequently you will relocate it.

Frequently asked questions
What is a whole house generator?
A whole house generator provides backup power to your entire home during an outage. It can automatically start and run essential appliances.
How do I determine the right size generator for my home?
To find the right size, add up the wattage of the appliances you wish to power. Aim for a generator that exceeds this total by at least 20%.
Can I run a whole house generator on different fuel types?
Yes, some whole house generators are designed to run on various fuel types, such as gasoline, propane, or natural gas. These are known as tri-fuel generators.
Is it safe to use a generator indoors?
No, generators should never be used indoors. They produce carbon monoxide, which is poisonous in enclosed spaces.
How often should I maintain my generator?
Regular maintenance is essential. Check the manufacturer’s guidelines but aim for service every six months or after extended use.
What to look for
Power Capacity
A generator’s power capacity is critical for ensuring it meets your needs. Look for models with enough wattage for your home. A typical small home may require 5,000 to 10,000 running watts, while larger homes often need 20,000 watts or more. Always consider the wattage of your essential appliances.
Fuel Efficiency
Fuel efficiency matters for both cost and convenience. Generators designed to run on gasoline or propane show different efficiencies. Tri-fuel generators can be advantageous as they allow users to choose the fuel type that is most convenient and cost-effective.
Noise Levels
Noise levels can affect your comfort and that of your neighbors. Look for generators that operate at around 60 dB for quieter performance. This noise level is similar to a normal conversation and less disruptive.
Size and Portability
If you need to move your generator, consider its size and weight. Some portable generators weigh less than 100 pounds, making them easier to transport. Check for features like wheels and handles for added convenience.
Warranty and Support
A good warranty can provide confidence. Most reputable brands offer warranties ranging from 2 to 5 years. This coverage can protect you from defects or issues that may arise after purchase.
