"Vitality arrived within an hour of contacting Firefly electric for an estimate to install an extra outlet in my home. We had 2 other estimates and Vitaliy was by far the most reasonably priced. He was able to install it on the spot and did a great job. I would highly recommend Firefly electric and will be using them for all my future electrical needs."

"Can highly recommend this company. Service and installation was great. Very professional and friendly. Generators are in short supply, so plan early. Allow about three to four months for generator to be available."

"Serge and Reuben were very kind and professional. They showed up on time, managed the permits and inspections in record time. AND got the power company in my area on board in record time also! This in the middle of storm damage all over our town! When there were some issues with wiring (as there always is in a house built initially in 1940 and added to in no apparent plan, quirky but cool!) Serge explained them to me and we came up with a plan and though he could have, didn't charge me for the extra effort. We discussed some future projects as the remodel goes forward and he ran wires for them so it will be a go when we get there. I couldn't have asked for better service, better communication, better replacement equipment and better understanding when I wanted to change things on the fly. He will be my go to guy for all future projects and I would recommend him highly and plan to with everyone I know. He does commercial and residential and is truly a part of the pro family now"

"Key is very polite and professional. He was able to handle my issue quickly. Key noticed a faulty wire (not what he was here for), which is not the first time that’s happened in this house. He fixed it when he could have just left it. I appreciate his attention to detail. If it was possible to give him more than 5 stars, I would."

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.

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.
