"I used JP McCurdy to install recessed lights in my living room. The ceiling was sloped and very high and Shazeeb and Nico did a great job. They also installed overhead lights in bedrooms and put in a 240-volt outlet for a washer/dryer room. They communicated with me about my preferences throughout the job. Their work was professional and clean. They also patched the holes they made, which some electricians wouldn’t do."

"Adam called me immediately and met me that same day. I hired the company and they cut my grass that same day. They used a ride on mower and my land is uneven so some areas were shorter than others. Two days later they spread 10 yards of hemlock mulch and recut some areas of my grass with push mower. They will use a push mower in the future. My yard now looks beautifully landscaped. Communication is definately key with this company. They aim to please!!"

"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

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.

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.

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
