Q: How long does a whole-house generator last?

• <div><p>When maintained properly, a whole-house generator can last up to <b>20 years</b>. <a href="https://www.angi.com/articles/how-much-does-generator-repair-cost.htm">Costs to maintain and repair generators</a> vary by location and type of generator, but you can expect to pay about <b>$150 to $300 per year</b> for annual generator maintenance checks. An experienced generator service technician will inspect your generator&rsquo;s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible. </p></div>

Q: Is it better to repair or replace a malfunctioning generator?

• <div><p>It&rsquo;s usually better to repair your generator if it isn&rsquo;t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around <b>$300</b> on average, while <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">installing a new whole-house generator costs</a> around <b>$5,000 </b>on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.</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>

Had a gutter system installed this fall. The customer service reps were friendly and knowledgeable. After install, saw a small concern in which they immediately came out and addressed. Problem was more the roof than the gutter system actually.
