What size generator do I need for my house?

Q: Is a natural gas generator less expensive than using electricity?

• <div><p>Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It&rsquo;s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator&rsquo;s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.</p></div>

Q: What is the life expectancy of a whole house generator?

• <div><p>Whole-house generators can last<b> 20 to 40 years</b> with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.</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>
