Customers say: Quick response

"Midnight Sun did an excellent job installing my garage sub panel. They arrived right on time and went straight to work. While digging the trench they encountered a lot of large rocks. It truly took a major effort to complete. But they just put their heads down and got it done. It is great to see such a high work ethic in a young business man. I would defiantly hire Midnight Sun again. And will recommend them to anyone in the need of the services they provide."

"Jordan Blake from Exceptional Electric rocks! His communication prior to coming out was very thorough, and he was able to schedule us in two days. While he was onsite he found multiple items from years of DIY wiring, one major one. He clearly communicated al recommended changes to better match current code. As to the major item, he discovered the transformer was causing over-voltage delivery into our main! He had me call United Electric, and the linemen were out even before Jordan left – kudos to U.E. Cooperative – and replaced the transformer on the pole. All this for what started out as just putting a new 30A circuit in for a mini-split! Our mini-split is not yet on site, so we look forward to having Jordan back to the farm to complete the electrical plus a couple of the found issues next week. He is so knowledgeable. I highly recommend him. His sense of humor is also a delight, and my husband enjoyed learning and discussing many things with him. His prices are excellent."

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
