"I had 2 ceiling fan/lights installed in the bedrooms. Installation included 2 new circular circuit boxes in each bedroom ceiling. In addition, I replaced the kitchen ceiling light with an LED fixture. The 2 workers were very polite and professional and worked quickly and efficiently, in addition to being respectful of my personal belongings."

"The consultation with Sean was very helpful and corrected the unit we actually needed. The work was done in a timely way, very professional and thorough. The hook up of the transfer switch was perfect on the trial runs with the generator. Sean has quiet confidence that he communicated with me and gave me the trust I needed to work with his family business that was new to me. I would go right back to Fitzgerald again. Good team, good work, and good service."

"We needed to install an EV charger receptacle quite far from the electrical panel. Chris suggested leading individual wires through a conduit instead of simply using Romex, saying that heat characteristics are better. He also wanted to know what EV charger we were getting and asked for documentation. We also discussed other aspects of the work. His genuine interest and attention to detail made us choose him. At the end, we were impressed with the quality of the work he delivered and how easy it was to communicate with him. He charged about the average price for this work but delivered more than many other electricians would do."

"Edgar is very detailed, respectful, professional with very good customer service! He showed up on time and completed the electric panel change sooner than expected! I have already referred him to my cross the street neighbor, Diane. Hopefully she will reach out soon for an estimate to change out her electrical panel too. Thank you ð ð"

"The installers were very sweet and professional. But I donâ t think I was made completely aware of how the exterior installation would look. The last 4 or 5 feet of the white pipeline are not covered and it looks unfinished and messy."

Customers say: Quality work

"The owner was onsite withing a week on the weekend to quote the job. Each of the employees that were on site on this project were very friendly and hit the ground running everyday they were onsite. We did a lot of the drywall ourselves which took us longer than expected but the owner followed up periodically to see how we were progressing so they could return install the outlets, switches and wall plates. Which was greatly appreciate as it pushed us along to get things done sooner rather than later."

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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. 

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
