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: 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: What happens with the generator when the local power goes back on?

• <div><p>If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you&rsquo;ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.</p></div>

Q: What happens if my whole-house generator is too small for my AC?

• <div><p>An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home&rsquo;s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.</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>
