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: Can a 10,000-watt generator run a central AC unit?

• <div><p>A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.</p></div>

Q: What incentives or rebates are available for home wind turbine installation?

• <div><p>Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.</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: 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>

When the company came out for the estimate everything went as planned. I just decided to go a different route. During the estimate they were very thorough in explaining the process and what would happen.
