"They did excellent work on many different items. Had a light installed over the sink (replaced a canister with light), re-wired outlets for kitchen remodel, and installed Ring doorbells. Showed up on time (key for me) and did nice work on all of the items. I would definitely have them do any other electrical work for me."

"Shawn Powell scheduled an installation and overview of my security system for 5/14/2021 and he was here promptly on that day. He had to detour on his way to my house but he texted me to let me know he was delayed. Shawnâ s customer service is impeccable. When he got to my house I had on my mask, he respected my home and put his on. When he had everything installed he gave me all the instructions I needed to use my system. If you want great customer service, a professional installer and top of the line security system for an affordable cost, Shawn is your man. I highly recommend him."

"Mr. Bailey was absolutely amazing. I have an older house and even simple projects become complicated fast. Mr. Bailey visited my home three different times and every time was a great experience for me. He showed up on time, every time. He was very easy to contact and he kept me informed of what was going on at every step of the job. He was incredibly professional even when my old house threw curveballs at him. I am so impressed with all of the work he did for me and my spouse and I will absolutely recommend him and hire him again if/when we need more electrical work done. Mr. Bailey is a joy to work with and he truly cares about his work. I can’t say enough about how much I appreciate him and his dedication to figuring out the puzzle of my house and making sure me and my family are safe in our home."

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
