Get matched with top generator install pros in Henderson, NC

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: 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>

Q: Where can you install a whole-house generator?

• <div><p>Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.</p></div>

Q: Do I need a permit to install a home generator?

• <div><p>Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.</p></div>

Q: Can a 10,000-watt generator run a central AC unit?

• <div><p>A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.</p></div>

"I need my automatically starting generator to work any time the regular power goes out. When I lost electricity last summer, the generator did not start. I found Larry locally, he was very professional on the phone. I was impressed when he came to my house and as he diagnosed the problem he did not just tell me, but showed me the problem (which was a problem with the board as well as a battery problem). He fixed the problem quickly and for a fair price. I was impressed and will hire him again if I ever have a problem again."
