Q: How much does it cost to install a generator?

• <div><p>The typical <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">cost of a home generator</a> is around <b>$5,000</b>, but prices range from <b>$400 up to $13,000</b>, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between <b>$500 and $2,000</b> or a partial-home generator for between <b>$2,000 and $6,500</b>. Whole-home generators usually total between <b>$5,000 and $13,000</b>, with some models climbing as high as <b>$18,000</b>.</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>

Q: Can you run a whole-house generator constantly?

• <div><p>Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.</p></div>

Q: How does a generator transfer switch save me money?

• <div><p>It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you&rsquo;ll have to pay between <b>$400 and $2,500</b> to have the transfer switch installed, you&rsquo;ll recoup that amount later on when you don&rsquo;t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect <a href="https://www.angi.com/articles/how-to-hook-up-generator-to-house.htm">hook up of a generator to your home</a>. </p></div>

Q: Do natural gas generators produce carbon monoxide?

• <div><p>If you&rsquo;re wondering <a href="https://www.angi.com/articles/do-natural-gas-generators-produce-carbon-monoxide.htm">whether gas generators produce carbon monoxide</a>, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every<b> 6 to 12 months</b>. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.</p></div>
