Generator Install FAQs, answered by experts

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.

If you’re wondering whether gas generators produce carbon monoxide, 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 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.
