Get matched with top generator install pros in Landrum, SC

Q: Can I plug my generator directly into my house?

• <div><p>No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding&mdash;power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.</p></div>

Q: What can I run on different generator sizes?

• <div><p>Here&rsquo;s what you can run with different wattages and types of generators:</p><p>Portable generator:</p><ul><li><p>2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. </p></li><li><p>4,000 watts will keep two large appliances operating and a few smaller devices.</p></li><li><p>8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.</p></li></ul><p>Partial to whole-house generator:</p><ul><li><p>20,000 watts and above will make it seem like your home&rsquo;s power is still on.</p></li></ul><p></p></div>

Q: How many days can a standby generator run continuously?

• <div><p>The <a href="https://www.angi.com/articles/how-long-can-whole-house-generator-run-continuously.htm">amount of time a standby generator can run continuously</a> is around <b>3,000 hours</b> on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home&rsquo;s natural gas supply are the best option for extended usage, as these won&rsquo;t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won&rsquo;t last as long, as these require fuel storage and regular refueling to stay running.</p></div>

Q: What’s the lifespan of a natural gas generator?

• <div><p>When properly maintained, natural gas generators can last a long time, as much as <b>20 to 40 years</b>. They have relatively few needs compared to generators with other fuel types. However, the generator&rsquo;s lifespan ultimately depends on how often the generator is used and for how long it&rsquo;s left running.</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>
