"Bill H from Gambino Electric showed up promptly on time for the job. There were some edge ceiling tiles that needed to be removed to reach the power line and Bill did very clean work with the removal and disposal. Bill showed cross sections of the older range power line and the new line installed, describing the differences in insulation and safety features of the newer line. Bill went above and beyond by detecting the wrong cord on the new range, and replaced this with the proper range gauge power cord. Bill also helped us to correctly position and level the new range appliance. I would recommend Bill and Gambino Electric for any similar household wiring job where safety and quality of work are a priority."

"Carlos is a PRO. Came out installed a new 200 amp electrical panel, conduit protected 200 amp line in, full bonding and grounding system, as well as ran a line and installed a generator interlock kit. He was thorough in showing me how to operate everything, the craftsmanship of his work was next level, everything up and running in a timely manner, and the cost was great. 10/10 would recommend for any and all electrical needs."

"Troy did an amazing job on several projects for us. He installed a 220 sub panel box and wired in a new hot tub. Additionally, he wired up our basement during a remodel, same as a new construction build. We hired him back on for the project due to the professionalism and fairness he brought with him on his first job with us. I’m a meticulous guy and picky about how my electrical work looks. Troy came in above and beyond of what I was expecting with his order of neatness and cleanliness when laying his lines. Everything had to be perfect for him and I feel he exceeded what my high expectations were already. I would certainly only consider him for whatever our next electrical project is."

Generator Install FAQs, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

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

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
