"Initially, he responded within the hour when I posted my request then he came to the house. From there on, in terms of your appointments, there was a back and forth. I was very determined to encourage him. But he had me waited for an hour and it was disrespectful for me. I thanked him when the appointment is kept being cancelled to contact the electric company. He wanted me to do it, he finally did it and then they rescheduled. But now, from this point on where is additional work, that their company wishes the company is requiring.

Hey I am David the owner of Dave’s Electric LLC. Certify electrical technician specialize in all electrical work residential etc! I pride myself on the quality work I provide, while delivering great customer service. Check out the services offered below and call -or- click to schedule an estimate today!
"My main purpose was to fix the circuit connected to the fridge and router. He said the panel must be replaced to fix it. He replaced the panel and the circuit appeared to be working. However, the steam shower stopped working because he mistakenly connected it to a 110 power source instead of the original 220. I called him few days later and he sent his guy who fixed the steam shower connection. About a month later, the circuit in question stopped working properly and we had to connect the fridge and the router to another circuit through a long extension cord, which we still have until now. I called and left messages and he refused to respond."

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
