"We wanted to update our dated kitchen, and needed to upgrade multiple aspects of the electrical. We called Current Electric on recommendation from a friend who had used their services in the past. Through the entire process of replacing the old lighting with more modern fixtures, installing an outlet in the pantry for our toaster oven to free up counter space, and adding a switch under the sink for the new garbage disposal we had plumbers install beforehand, these contractors were friendly, professional and knowledgable. They worked in a timely manner that allowed us to stress less about the project and enjoy the new look and function of our updated kitchen. Everything works just how we had hoped and we intend to use their services for any future electrical work."

"I hired Bayou for what I thought was a minor problem. As it turned out I had a very serious problem with my electrical panels both inside and out. The technician was very helpful and informative and showverme in detail what my problem was.The service was great and over and above what I would expect. Since the problem was a danger to my home, they moved very fast to fix the problem. I cannot say enough about the stellar service. As far as price is concerned, because the problems grew, the service e tech did manage to discount the second phase of the project. I do not know , frankly, if the cost is comparable to other companies, but I am grateful I did not have an electrical fire and that my home is intact. I highly recommend Chris as a technician. He did not leave the day of service until he was sure I was safe in my home until the remaining part arrived and was installed."

"Hired a professional to install 2 hand rails for my parents. One was installed on the front porch brick steps and one on the back porch brick steps. They arrived on time, installed both handrails quickly and safely. Handrails are sturdy, and now my parents lives are that much safer. Would recommend."

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
