"I needed a generator transfer switch installed before the storm. Mark with A+ Electric came out within the hour and gave me a very reasonable quote. He wired my house for a generator the following day!! Thoroughly impressed!! He was very nice and ensured I knew how to operate everything in case of an outage. His work was very neat and professional. I will definitely use him again."

"Paul was professional and very meticulous. Initially he came to my home to view the project and gave me a free estimate for the work to be done. I got on his schedule, and he was prompt in his arrival to include calling me once he was about 20 minutes from my house. Paul removed an old vanity light, skillfully patched up the hole and prepped the wall to install two new vanity lights in different locations. By doing this, he had to run two additional lines behind the drywall to provide power for the two vanity lights. The two vanity lights were precisely marked and placed evenly over each mirrow and sink. Paul also removed a wall outlet from the front wall, patched that hole and installed a new wall outlet on the side wall to make the vanity area look the same on both sides of each sink. The new side wall outlet required Paul to enter the crawl space to run a dedicated line up to it. Once all work was complete, everything thing was tested to ensure it was in excellent operating condition and safe. The area was cleaned including the counter space and the floor insuring nothing was left behind for a job well done. My next electrical job, I will definitely call Paul Higginbotham."

"Carlton and Tony were extremely professional and knowledgeable. They diagnosed the problem immediately and found where the electrical problem occurred, and why it occurred. They fixed the electrical issue immediately and recommended new GFCIs be installed. They were both great and very friendly, explaining why the outlets were wired in the circuit in the layout of the area in the house. I would whole heartily recommend this company and these two gentlemen for any electrical work."

"I called and they were out the next day. It was more than just one fixture. They also fixed another person's mistake, and they redid a messy outside light and pump situation by a pond. They were very fast--I was expecting almost twice as long to get it all done. I am extremely happy and they are on my very short list now."
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
