Q: What size whole house generator do I need to run central AC?

• <div><p>To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right <a href="https://www.angi.com/articles/whole-house-generator-sizing.htm">generator size</a>. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.</p></div>

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

• <div><p>The <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">cost to install a whole-house generator</a> averages at <b>$5,200</b>, but costs can range from <b>$1,500 to $8,900,</b> depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don&rsquo;t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.</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: Do diesel generators have any important downsides?

• <div><p>While diesel is relatively stable, it won&rsquo;t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it&rsquo;s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn&rsquo;t always ideal for home use. </p></div>
