"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

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.
