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: Do you have to turn off the main breaker when using a generator?

• <div><p>As a safety measure, you should always turn off the main breaker while operating your generator&rsquo;s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.</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 can I run on different generator sizes?

• <div><p>Here&rsquo;s what you can run with different wattages and types of generators:</p><p>Portable generator:</p><ul><li><p>2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. </p></li><li><p>4,000 watts will keep two large appliances operating and a few smaller devices.</p></li><li><p>8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.</p></li></ul><p>Partial to whole-house generator:</p><ul><li><p>20,000 watts and above will make it seem like your home&rsquo;s power is still on.</p></li></ul><p></p></div>

Q: What happens if my whole-house generator is too small for my AC?

• <div><p>An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home&rsquo;s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.</p></div>

Good People, Tony the owner is one of the most onest general contractors I've met. I have hire him for a couple projects and never disappoints, especially on the times where I needed to wait for him to start.

My general contractor wanted $1800 to replace my 1-car garage door. I thought that was nuts, and I had found him to be very difficult to deal with, so I checked the list and called Juliao. They came out a few days later and said the old door could be saved, but that an inspector might insist...

I couldn't be happier with the service. Elliot and Jay not only installed my projector and connected all my other devices to it, they also cleaned up after themselves and were generally as professional as can be. I would definitely use again, and have referred several friends to him.
