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>

Q: What happens if my whole-house generator is too small for my AC?

• <div><p>An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home&rsquo;s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.</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>

Q: Should I buy a solar battery or a generator?

• <div><p>If you&rsquo;re deciding between a <a href="https://www.angi.com/articles/solar-batteries-vs-generators.htm">solar battery versus a generator</a> for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don&rsquo;t have many ongoing costs. </p></div>

Q: Do diesel generators have any important downsides?

• <div><p>While diesel is relatively stable, it won&rsquo;t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it&rsquo;s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn&rsquo;t always ideal for home use. </p></div>

"I first asked for a quote back in February of 2024. When I received the quote I decided to wait on this project. Then we lost power for 2 days due to a storm. I then decided it was time and contacted the contractor again. He sent me an updated quote and the project was scheduled. It's now installed and I'm very happy with how it turned out. Hopefully it will be a long time before we need to use the generator because we lose our power. But we are ready when it happens. I will definitely use this company again for any electrical jobs that come up. Andrew and his crew were great."
