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’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’s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</p></div>

How does a generator transfer switch save me money?

• <div><p>It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between <b>$400 and $2,500</b> to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect <a href="https://www.angi.com/articles/how-to-hook-up-generator-to-house.htm">hook up of a generator to your home</a>. </p></div>

Q: What’s the normal lifespan of a diesel generator?

• <div><p>You can expect a diesel generator to last for up to <b>30,000 hours of use</b>, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. </p></div>

Q: How much horsepower do I need?

• <div><p>If your home already has a grinder pump and you&rsquo;re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.</p></div>

Q: Is it safe to run a generator continuously?

• <div><p>It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer&rsquo;s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you&rsquo;re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning. </p></div>

I have used them for multiple jobs on multiple locations, they are amazing. They show up on time they get things right and I don’t have to call them back. I’ve had experience with other plumbers that I have to call back and they don’t respond. This one does it right the first time
