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’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.</p></div>

Can a natural gas generator work without electricity or in a power outage?

• <div><p>Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a <a href="https://www.angi.com/articles/cost-install-generator-transfer-switch.htm?entry_point_id=33797025">transfer switch</a> (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.</p></div>

Q: What are the disadvantages of a standby generator?

• <div><p>While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.</p></div>

Q: How can I reduce carbon monoxide emissions from my natural gas generator?

• <div><p>Carbon monoxide emissions aren&rsquo;t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. </p></div>

Q: Is using a generator safe?

• <div><p>As long as your generator is used as recommended by the manufacturer, it&rsquo;s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator&rsquo;s placement and set-up meets safety standards when installing or repairing your back-up power source.</p></div>
