Q: Can you run a whole-house generator constantly?

• <div><p>Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.</p></div>

Q: How much does it cost to install a generator?

• <div><p>The typical <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">cost of a home generator</a> is around <b>$5,000</b>, but prices range from <b>$400 up to $13,000</b>, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between <b>$500 and $2,000</b> or a partial-home generator for between <b>$2,000 and $6,500</b>. Whole-home generators usually total between <b>$5,000 and $13,000</b>, with some models climbing as high as <b>$18,000</b>.</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: Can you switch fuel types for a whole-house generator?

• <div><p>In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.</p></div>

Q: Is it worth it to install a whole house generator?

• <div><p>A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home&rsquo;s value, especially in areas prone to extreme weather and power outages. </p></div>
