Q: Does installing a generator increase home value?

• <div><p>Yes,<a href="https://www.angi.com/articles/generator-installation-avoid-electrical-disasters.htm"> installing a generator</a> usually increases your property value because buyers are getting the added peace of mind knowing they&rsquo;ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly. </p></div>

Q: How do I know what size of whole house generator to choose?

• <div><p>Generators are usually sized by running watts and starting watts. Ideally, you&rsquo;ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. <a href="https://www.angi.com/articles/electrical-load-calculation.htm">Calculate your home&rsquo;s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</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>

Q: How close can a transfer switch be to a generator?

• <div><p>Generally, you&rsquo;ll want to keep between <b>60 and 70 feet</b> between the generator and the transfer switch. There are a few reasons for this, including:</p><ul><li><p>The distance reduces the noise coming from the generator into your home.</p></li><li><p>It increases efficiency because you won&rsquo;t have a voltage drop from this short of a distance.</p></li><li><p>Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. </p></li></ul><p></p></div>

Q: Is it better to repair or replace a malfunctioning generator?

• <div><p>It&rsquo;s usually better to repair your generator if it isn&rsquo;t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around <b>$300</b> on average, while <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">installing a new whole-house generator costs</a> around <b>$5,000 </b>on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.</p></div>
