"Very quick to respond, excellent customer service skills, completed the job within a couple days from contact, and provided instructions on how to connect our new generator to the power inlet, and how to engage the system. Jestin is a nice young man trying to grow his new business. I am glad to refer him to anyone I know. Thank you Jestin"

"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 had an amazing experience with our electrician! He handled everything from installing our switches and outlets to completing the electrical wiring with incredible attention to detail. He also installed and wired our garage door motor flawlessly, and made sure everything, including the subpanel, was done properly and safely. What really stood out was his professionalism and work ethic. He kept everything clean and organized, which made a huge difference It’s not easy finding someone this reliable, skilled, and thorough. Highly recommend to anyone looking for quality electrical work done right the first time!"

"Overall experience was average. First day of installation was okay until I find out half of the house did not have power. Edgar came back the next day and explained the cause and fixed it with ease. Was getting push back about how everything was installed as it was and there shouldnâ t be any issues, well there was and he graciously came back and fixed the problem. I would definitely use this company in the future."

"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

"Stephen was knowledgeable about the Code requirements for Oakland (not all of the electricians who quoted on the job were) and flexible in working through the equipment needs (a panel and a subpanel). He and his crew (Jeff and Tom) were quick, clean and efficient in the installation and the price for the work was fair. I definitely would hire them again if I need more electrical work."

Generator Install questions, answered by experts

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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.
