"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."

"We had Frank replace a chandelier in the kitchen, replace dimmer switches in our living room, install ceiling fans with lights and corresponding light switches in 4 upstairs bedrooms as well as recess lights in our master. He also installed an additional outlet for a bidet in the bathroom. He and Dave were great to work with, Dave provided quotes in advance and they were reasonably priced. Frank also helped guide our decision on some of the work and was very honest about what would and would not work in our bedrooms—even if it generated less revenue for him. We will definitely hire them again!"

"We had an outlet installed in a cabinet for an Over the Range Microwave.  They ran the line with no damage to ceilings or drywall which involved some creative thinking which we were thankful for. Install went well.  Was fast and done with no mess or dirt.  Professional and on time.  Outlet works well. (They did not install the microwave, we did that ourselves.)  Very satisfied and would hire them again if ever needed.

"The guys did an excellent job. They were pretty efficient. Work was done quickly and they cleaned up after themselves. There was an issue with the estimate as the person estimating the job missed on the length of the wire so the start was delayed while the techs had to go get more wire. Initially the charger did not work as this was the first time they had to install this type. That being said they worked it out and all is good. I would hire them again"

Generator Install questions, answered by experts

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
