Q: Do I really need a generator transfer switch?

• <div><p>Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for <a href="https://www.angi.com/articles/what-is-an-electrical-emergency.htm">electrical emergencies</a>. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. </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: 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>

Q: How do I know what size generator I need?

• <div><p>When <a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">choosing the right size generator</a> for your needs, consider a few items to help calculate the wattage you&rsquo;ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:</p><ul><li><p>Refrigerator: 600 watts</p></li><li><p>Large dehumidifier: 700 watts</p></li><li><p>Large window air conditioner: 1,400 watts</p></li><li><p>Water heater: 3,000 watts</p></li></ul><p>Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. </p></div>

Q: Is it better to repair or replace a malfunctioning generator?

• <div><p>It&rsquo;s usually better to repair your generator if it isn&rsquo;t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around <b>$300</b> on average, while <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">installing a new whole-house generator costs</a> around <b>$5,000 </b>on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.</p></div>

Salesman was great; installers were fast; cleanup could have been better. The seal job was no so good; I had some food stains that did not come out with just washing and I had to have them come back out and re-seal .
