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>

Q: Where can you install a whole-house generator?

• <div><p>Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.</p></div>

Oni & 3 of her gals did a whole house deep clean for the first time today. Four hours total onsite work time. Zoned effort floor-to-floor allowed for inspection & fixes. Gals didn't replace furniture where it was originally, but at least it was moved! Generally pleased with results.
