Q: Do installations include unit assembly?

• <div><p>Many services include assembling the unit and securing it in the window. Confirm with your provider.</p></div>

Q: What’s the lifespan of a natural gas generator?

• <div><p>When properly maintained, natural gas generators can last a long time, as much as <b>20 to 40 years</b>. They have relatively few needs compared to generators with other fuel types. However, the generator&rsquo;s lifespan ultimately depends on how often the generator is used and for how long it&rsquo;s left running.</p></div>

Q: What size of diesel generator do you need to run a house?

• <div><p>Sizing a generator is a careful process that requires calculating the <a href="https://www.angi.com/articles/electrical-load-calculation.htm">electrical load</a> of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.</p><p>In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. </p></div>

Q: What happens with the generator when the local power goes back on?

• <div><p>If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you&rsquo;ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.</p></div>

Q: Is it worth it to install a whole house generator?

• <div><p>A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home&rsquo;s value, especially in areas prone to extreme weather and power outages. </p></div>
