"William was prompt, set expectations and followed through and educated us on the need for a Surge Protector. He came for a quote but was able to install the EV charger quickly and cleanly same day. He is very knowledgeable about the EV market and was in and out quickly. Great experience all around. Highly recommend!!"

"Needed electric service run from the breaker panel in my house to a newly installed workshop in back of my house. They ran the service and installed a sub-panel, 6 outlets, 3 overhead junction boxes, and 2 junction boxes for outdoor lighting. They gave me a good quote and did the installation in 1 day. Arrived when they said they would and performed quality work. Very pleased with the installation. I would definitely hire these guys again."

"I'm blown away by the fantastic service. I was trying to get ready for Hurricane Matthew and needed a generator outlet installed. Called and got a call back immediately. Ken was great to work with, installed the outlet while I had to head out of town. I was extremely worried about the hurricane and Ken's was so helpful that I knew we'd have what we needed when the storm hit. He even checked our old cable and suggested that we buy a new one, stayed on the phone with my wife to make sure the right one was ordered. I can't say thank you enough. This is why you deal with highly reputable local companies, they go the extra mile. Highly recommend them without reservation."

Generator Install FAQs, 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

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

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.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
