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’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>

What are the pros and cons of using a natural gas generator?

• <div><p>Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">installation costs</a>, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. </p></div>

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>

What size generator do I need for a 1500-square-foot house?

• <div><p>A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the <a href="https://www.angi.com/articles/how-many-watts-house.htm">total wattage</a> of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.</p></div>

Responded quickly. Job very well done. Installers were polite, efficient, cleaned up (including vacuuming) before leaving. It also provided advice on how to maintain and how long to wait for caulking to cure before painting. I would definitely hire again for such work.
