"Current Electric was able to come to the house quickly and got everything fixed. Overall a very good experience though we found their price to be a bit high given the time spent (less than an hour)."

"I recently had the pleasure of working with Joe Brewster (owner Elevation Electric), a licensed electrician, to install a Level 2 electric vehicle charger at my home, and I couldn’t be more thrilled with the experience! From start to finish, Joe’s professionalism, expertise, and customer-focused approach made the entire process seamless and stress-free. Joe was incredibly knowledgeable, taking the time to explain the installation process, recommend the best charger for my EV, and ensure everything met local codes and safety standards. He arrived on time, equipped with all the necessary tools and materials, and worked efficiently without cutting corners. The attention to detail was impeccable—every wire was neatly installed, and the charger was perfectly positioned for convenience. What truly stood out was Joe’s commitment to customer satisfaction. He patiently answered all my questions, offered tips on optimizing my EV charging setup, and even followed up after the installation."

"Our technician provided us a quote and installed our ceiling fan on the same day within 2 hours. The install required new wiring in a room with no existing wiring. The price was affordable, the install was fast and they cleaned their work area well. Highly recommend."

"This was not your average ceiling fan install. We had to navigate around ceiling joists because there wasn't attic access to pull the wiring. Cory was great, he offered a solution and was very polite. I am a mom with a one year old and I felt comfortable having him in my house. I would definitely hire him again."

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
