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: 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>

Q: What’s the normal lifespan of a diesel generator?

• <div><p>You can expect a diesel generator to last for up to <b>30,000 hours of use</b>, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. </p></div>

Q: How much does portable generator installation cost?

• <div><p>Costs range from $500 to $2,500, depending on generator type and installation complexity.</p></div>
