"I had an outstanding experience with Miguel and highly recommend him for any electrical work! He arrived on time, was incredibly warm, courteous, and professional throughout the entire process. Miguel went above and beyond by securing a permit from the county, installing a transfer switch for my new generator, and even arranging for the inspector to come the same day. The installation was completed quickly, accurately, and at a great price. His attention to detail and commitment to customer satisfaction were exceptional. I will definitely hire Miguel again for any future electrical needs. Five stars!"

"These guys were AWESOME. I received 4 quotes Cape Fear came in the lowest with exactly what I wanted, Shane was the salesmen we talked more about the days events then the actual project. When he left he felt like an old friend. He Emailed me my quote and came in $2000,00 less then the other guys with a Trane high efficiency (96% 2 stage furnace and new A/C Unit) the other quotes I got was for a single stage 80% plus ac for more money. The Installer Joe and his crew were great. he took time to answer my questions and ran a new return line from the floor and put it in the ceiling, I definitely got my moneys worth. DO NOT HESITATE TO HIRE THEM!!!!!"

Generator Install questions, answered by experts

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

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.
