Q: How do I know what size generator I need?

• <div><p>When <a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">choosing the right size generator</a> for your needs, consider a few items to help calculate the wattage you&rsquo;ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:</p><ul><li><p>Refrigerator: 600 watts</p></li><li><p>Large dehumidifier: 700 watts</p></li><li><p>Large window air conditioner: 1,400 watts</p></li><li><p>Water heater: 3,000 watts</p></li></ul><p>Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. </p></div>

Q: What size generator do I need for a 1500-square-foot house?

• <div><p>A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the <a href="https://www.angi.com/articles/how-many-watts-house.htm">total wattage</a> of the devices that you&rsquo;d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.</p></div>

Q: Can a 10,000-watt generator run a central AC unit?

• <div><p>A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.</p></div>

Q: What size generator do I need for my house?

• <div><p><a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">Generator size requirements</a> vary wildly among properties, but typical generator sizes are listed below based on home square footage:</p><ul><li><p>1,000 sq ft: 6&ndash;9 kW</p></li><li><p>1,500 sq ft: 7&ndash;10 kW</p></li><li><p>2,000 sq ft: 10&ndash;14kW</p></li><li><p>2,500 sq ft: 12&ndash;16kW</p></li><li><p>3,000 sq ft: 16&ndash;20kW+</p></li></ul><p>Unfortunately, home square footage isn&rsquo;t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you&rsquo;d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.</p></div>

Q: How do I know what size of whole house generator to choose?

• <div><p>Generators are usually sized by running watts and starting watts. Ideally, you&rsquo;ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. <a href="https://www.angi.com/articles/electrical-load-calculation.htm">Calculate your home&rsquo;s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</p></div>
