"We highly recommend J.P. McCurdy Electrical Services. We hired this exceptional shop to replace all the old knob and tube wiring (along with switching out a number of light fixtures and installing several ceiling fans) in our 120-year-old Victorian home – a challenging job that a couple of other electricians didn’t feel confident undertaking. Owner Jack McCurdy personally came to size up the job and give us a detailed estimate, and his professionalism, courtesy and extensive knowledge sold us. What was originally thought to be a two-week job was finished in six working days as foreman Joe Costain efficiently deployed his crew and brought in a second crew on a few days to expedite the work. Joe was great at communicating what kind of activity we could expect day-to-day, especially as both my wife and I are working from home fulltime during the COVID pandemic. He and the crew checked in frequently on our preferences, minimized the number of holes in the ceilings and walls (including avoiding harming our wallpaper in a couple of rooms altogether), and cleaned up well at the end of every day. Jack’s estimate was competitive and the final accounting accurately included the additions and subtractions we agreed to during the job. We feel so much better that we’ve finally eliminated the risky knob and tube wiring and updated the entire house’s electrical system. McCurdy is a full-service shop that does all kinds of electrical work – if you want a trustworthy and capable electrician, give Jack a call!"

"I had both electricians and plumbers who performed the work of the generator installation, transfer install as well as the plumbing to the propane tank-generator. Considering the time of year with hurricanes and inclement weather, the generators and transfer switches were backordered however, my job was completed within a 2 month period from the initial quote to finish- considering all of the obstacles that we faced, they did a fantastic job."

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

Generator Install questions, answered by experts

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.

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
