Q: How much does it cost to install a whole-house generator?

• <div><p>The <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">cost to install a whole-house generator</a> averages at <b>$5,200</b>, but costs can range from <b>$1,500 to $8,900,</b> depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don&rsquo;t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.</p></div>

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: 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: Can I plug a generator directly into my house?

• <div><p>No, you shouldn&rsquo;t use an extension cord to plug a generator directly into your home without using a transfer switch. That&rsquo;s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of <a href="https://www.angi.com/articles/how-to-put-out-electrical-fire.htm">electrical fire</a> or electrical shock to you or any workers repairing lines on your local electrical grid.</p></div>

Q: What size generator does my house need?

• <div><p>You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. </p><p>A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you&rsquo;ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.</p></div>
