Get matched with top generator install pros in Wilmer, TX

Q: How long can a whole-house generator run continuously?

• <div><p>Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.</p></div>

Q: How do I know what size of whole house generator to choose?

• <div><p>Generators are usually sized by running watts and starting watts. Ideally, you&rsquo;ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. <a href="https://www.angi.com/articles/electrical-load-calculation.htm">Calculate your home&rsquo;s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</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: Is a home generator a tax write-off?

• <div><p>Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.</p></div>

Q: Are there tax credits for home generators?

• <div><p>In most cases, there are no tax credits available for home generators. However, that&rsquo;s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the <a href="https://www.dsireusa.org">Database of State Incentives for Renewables &amp; Efficiency (DSIRE)</a> for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.</p></div>
