"This young man was a Godsend for our family. We called many electricians, but all of them were booking out for months. Reid was able to come three days after we called him. We needed him to start service at our new house. He had to dig to install conduits, put in the breaker box, fix a disconnect box and an outdoor outlet outside the house, just so we could get electricity. All of that was done very nicely and professionally. And he cleaned up when he was done. He even helped us coordinate with the electric company. Any questions we had, he answered with the utmost patience and knowledge. He was just an excellent electrician, and we were very lucky to find him. And, his price was very reasonable too. I would hire Reid anytime! In fact, we have a few more projects lined up for him. My neighbors saw the good work that he did at our house, and so they are having him do some jobs at their house too."

"Jim for Donhohues Lightning Rods installed the lightning rod system in my home. When the work was done I was very happy as their installer came as per promised time, and perform the work. Before giving them the work Jim completely sold me their work ethics, quality, and service. There was a minor issue and his team took complete ownership of this issue and talked to me in detail. They provide a very good explanation to satisfy me. I am a happy customer."

"Anthony was very attentive to my project on an old building. He sought out a safe and viable solution to change out an old fuse box and relocate with a new breaker box. He was quick with a response to my request, inspection and quickly gave a solution with a quote. Once I accepted, he scheduled my work right away. He was also prompt on the day of installation and did the work professionally and quickly. I recommend A & A Electric and I would even recommend Anthony to my family and friends. - Pastor Jeff"

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
