Q: Can a portable generator power an entire home?

• <div><p>A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a <a href="https://www.angi.com/articles/installing-whole-house-generator.htm">whole-home generator</a> instead. </p></div>

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: 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&rsquo;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>

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

• <div><p>In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between <b>$50 and $250</b>, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you&mdash;and might be required to do so by your building department&mdash;but you&rsquo;ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.</p></div>

Q: What types of fuel do generators take?

• <div><p>Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:</p><ul><li><p>Natural gas: $2,000&ndash;$21,000 per year </p></li><li><p>Liquid propane: $2,000&ndash;$21,000 per year</p></li><li><p>Diesel: $3,000&ndash;$20,000 per year</p></li><li><p>Gasoline: $500&ndash;$3,000 per year</p></li><li><p>Solar generator: $2,000&ndash;$25,000 per unit</p></li><li><p>Battery backup: $10,000&ndash;$25,000 per unit</p></li></ul><p></p></div>

Very fast efficient service. The televised sewer inspection was pricey. The sewer rodding service was in line with what others charge. Their technician was courteous and helpful. He was at my house about an hour after I called. Very respectful and professional.
