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: What’s the lifespan of a natural gas generator?

• <div><p>When properly maintained, natural gas generators can last a long time, as much as <b>20 to 40 years</b>. They have relatively few needs compared to generators with other fuel types. However, the generator&rsquo;s lifespan ultimately depends on how often the generator is used and for how long it&rsquo;s left running.</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: Is it worth it to install a whole house generator?

• <div><p>A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home&rsquo;s value, especially in areas prone to extreme weather and power outages. </p></div>

Q: Is using a generator safe?

• <div><p>As long as your generator is used as recommended by the manufacturer, it&rsquo;s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator&rsquo;s placement and set-up meets safety standards when installing or repairing your back-up power source.</p></div>

Octavian and Justin were both extremely communicative and responsive. It was not easy to find pros for trim repair/replacement and they were able to quote and install in the same day at a great price. Will definitely be using them again for other work in the future.

This company was so fast to get me a quote. Communicated throughout the entire process but most of all did a GREAT job. They came back a second time to repair the fence doors as well. I wish I had contracted them initially to install the fence around my property! Thank you to the team!
