"Exceptionally satisfied. Our electrician, Ryan, is exceptional. He explained every detail and when faced with complex decisions his advice was top notch. One of the best we have ever worked with. The service was prompt, accurate, and in the end greatly added to the safety of our property. We feel we received a greater value for our money than we initially expected. Ryan always went out of his way to insure we were satisfied with the work he, and his assistants were performing. At every turn we found that he is a problem solver who gave us the pro's and con's on issues and viable alternatives. We will certainly use this service again."

Small jobs welcome

"We've used Scott for several projects over the years, and he's been fantastic every time. He was willing to take on some smaller jobs that many electricians wouldn't bother with, including replacing a floodlight that had been broken for years, installing a new Ring floodlight camera, and fixing an under-cabinet kitchen light. He responded quickly, showed up when he said he would, and got everything working perfectly. He also helped us with a much more complicated project when our new wine refrigerator wouldn't fit because an electrical box had been installed too far forward. It was right before Thanksgiving, and we were worried we'd be stuck without a solution. He was able to reroute wiring through the basement, relocate the box, and get everything finished quickly so we could install the fridge in time for the holiday. He's knowledgeable, reliable, reasonably priced, and does excellent work. It's hard to find contractors who communicate well, respond promptly, and genuinely care ab"

Generator Install questions, answered by experts

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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. 

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
