"Austin and his team have been wonderful to work with. We had extensive experience with them after our generator was struck by lightning. Austin was incredibly professional and reliable. He wrote letters to our insurance and helped us get our new generator covered he was very honest and knowledgeable. He patiently handled all the back and forth paperwork with the insurance, helped us pick a new generator and just gave us great advice and his prices were very reasonable. He even helped us get the new generator installed quickly before our new baby was born during hurricane season. I am so grateful we found him and highly recommend him and his team."

"My experience with Beachside Electrical could not have gone better. Randy was fast to respond and responsibly priced. They came out and installed my new fixtures in less time than expected. I will have them back for more work in the near future."

"Danilo and his paint crew are amazing! From the beginning, he was super responsive and let me know everything that was happening every step of the way. My job took about 4 days; each day I was contacted regarding start/end time, and what was being completed each day. The team also cleaned up each day and kept the work space neat and tidy. The finished product is beautiful! I would highly recommend this crew for any jobs and will be contacting them again for more work!"

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
