Get matched with top generator install pros in Brighton, CO

Q: How long can a whole-house generator run continuously?

• <div><p>Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.</p></div>

Q: Do you need a permit to install a permanent or whole-house generator?

• <div><p>In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between <b>$50 and $250</b>, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you&mdash;and might be required to do so by your building department&mdash;but you&rsquo;ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.</p></div>

Q: How long does it take to set up utilities?

• <div><p>Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.</p></div>

Q: How do I know what size of whole house generator to choose?

• <div><p>Generators are usually sized by running watts and starting watts. Ideally, you&rsquo;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. <a href="https://www.angi.com/articles/electrical-load-calculation.htm">Calculate your home&rsquo;s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</p></div>

Q: Can you use biofuel in a whole-house generator?

• <div><p>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.</p></div>
