"The company does great work. I am please with the work. They worked fast and were very friendly. They will be installing more lights for me in the near future. The lights that I bought for him to install in the kitchen doesn’t light up the kitchen enough, so since I liked the design of light so much the owner suggested that i place the same exact light in another area of the kitchen. Great idea. He was hundreds dollars cheaper than other quotes that I received. They do wonderful work. I have already recommended him to my sister that needs electrical work."

"Josh was the first electrician out of about 8 that finally got back to me and not only that, but he was very prompt, friendly and professional. I requested a quote for an interlock kit, 50a inlet and a breaker box (I have my own generator). Josh was able to give it to me with just a few pictures provided. Right there I booked him to come out the next week. He showed up right on time and got right to work. My wife was home as I’m on deployment and he was very friendly and when the install was done, gave her a rundown on how to use it all. I would highly recommend him and his company as this experience was one of the best ones I have had with an electrician but as well as any contractor I have needed so far since I purchased this home and have renovated it top to bottom. I will be calling him next time I need any electrical work done!"

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
