"Very responsive and professional. They installed a 60" TV onto a stone fire place. They did a great job and made sure to clean up all the dust from drilling into the stone before they left. All 3 of the staff wore masks while in our house which was appreciated. Would recommend."

"Lightning Bug Electric did a wonderful job. We had Josh & Jake come out to install a ceiling fan & a new switch for it in our two story living room. They were extremely nice, funny & professional. They taught us a lot about the home’s existing wiring, & recommendations to upgrade our house that were extremely helpful. The ceiling fan came out great, & the switch as well! I highly recommend them to anyone looking to get electrical work done the right way. Incredible!!"

"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."

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
