"They told us "Our dispatch fee to come out is $39 and we waive that towards any work or repairs, including diagnostics." The electrician went to check and stayed at the property for less than 5 mins after confirmation to do full diagnostic of the electrical system. I don't think less than 5 mins is enough to run a full diagnostic and later on advise to upgrade the whole panel."

"Very impressed -- the company was very professional, the technician (I think his name was Jeremy) was prompt, polite, and knowledgeable. We had originally planned just to have a light fixture in one of the bedrooms replaced, but that morning found a great deal on a Ring doorbell. We asked if he could install that, too, even though it was a last minute addition, and he agreed to install it with no problem. It's always nice to work with a company that is so on top of service! That is hard to find these days, so highly recommend this company."

"This is an American US Citizen company with working American employees. Cole arrived with 18 yrs of electrical experience. WOW he knows his stuff. I had a ancient electrical box with federal breakers which are known to cause fires. Cole said my old box was in bad shape. It was a no brainer to spend the money and upgrade to general electric breakers. I also hired him to hard wire my carbon and smoke detectors. Job #1 took 2 days. The other work will be done in August 2021. For an experience electrician this is your company."

Generator installations FAQs
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 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.
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
