Home Generator FAQs: For Your Whole Home

March 3, 2025      

How big does a generator need to be to run my entire house?

The size generator you need varies depending on the size of your home and your electricity usage. That said, a generator that produces around 10,000 watts is suitable for a small 1,500 square foot home while 18,000 watts is enough to handle a 2,500 square foot home.

How much does it typically cost to have a whole home generator installed?

You’ll pay around $6,000 to $10,000 for a standby generator, depending on its output, plus an additional $3,000 to $5,000 to have the generator installed. While standby generators are expensive, you can expect one to add between 3% and 5% to the value of your home.

Do I need a generator for my home?

Whether a generator makes sense for your home depends on a variety of factors. If you live in a rural area with aging power lines and frequent bad weather, it probably makes sense to have a generator on hand to supply you with backup power during an outage. A generator may also be essential if any members of your household rely on any electrically powered medical equipment.
