Customers say: Super punctual

"Three light fixtures installed to existing wiring, less than an hour to survey work, perform task, and do paperwork...$387...Really surprised my elderly parents and me...Just found out through this experience, they have taken over the electrical for Ragsdale Heating and Air, liked it better when Ragsdale did their own electrical...So buyer beware when dealing with this company."

"Jeremy Reel completed the install to perfection. He installed a 50A breaker and the Level 2 Charger. When the car was only charging to 32A he stayed and trouble shot the issue for an extra hour. As it turns out, 32A was the max the car would charge at. I was very satisfied with TE Certified and would recommend them to anyone."

"I called Lighting Bug Electric for a quote to install a generator transfer switch. The office was prompt with scheduling and called to let me know each time when a technician would be out and was on his way. Timing was accurate. Leo came out to give a quote. He looked everything over, listened to what we wanted, answered all our questions and made sound recommendations. I was very impressed with Leo and felt comfortable with the quote and his abilities. This wasn't our first transfere switch intall. I wanted Leo to do the install so I set up an appointment for install with him on the spot for the following week. Leo and Michael came out to do the install. Again the office called to let me know the were on thier way and would be arriving in about 35-40 minutes. I sat my Alexa for a reminder, they were exactly on time. The install was fast and efficient. Very little loss of power (inconvenience to me). Afterwards, Leo walked me through the operating process and again patiently answered all my questions. Michael whom Im assuming was his assistant was very pleasant and personable. Both were people you felt you could trust. They felt like *family doing the job, you knew you were in good hands. *Just FYI , my dad (who has passed) was a licensed electrician and had his own business. We were spoiled if we needed any electrical work, dad would do it. You know he was thorough. Im not an electrician but just growing up in the environment its easy to spot electricians that are sincere, knowledgeable, thorough and care. I highly recommend Leo and Lighting bug electric."

Generator Install FAQs, answered by experts

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.
