"Very disappointed. Poor communication. These guys had the wrong day to come on calendar. Never saw an estimate even though they said they mentioned it. When I asked how much it would be after they missed the first day, it was about $300 more than what Angi estimated repairs should be. I ended up installing three of those light fixtures myself after talking to them when they didn't show up on the first day. I let them know I installed 3 light fixtures and they were going to adjust the estimate. They never sent an updated price. The second attempt to come out, they didn't show at the appointment time. No phone calls, nothing. I didn't have much patience after waiting 35 minutes for some sort of communication. I reached out to see what was the deal. They seemed surprised that I would cancel the service and seemed like it was acceptable to not communicate because they were finishing up a service job. That's just poor service."

Hello, I'm Greg Avila owner of Avila Electric, a family-owned small business here in the upstate. I've been a journeyman electrician for 10-15 years and on the management side of electrical and general construction for another 10 years. I've worked in a variety of settings from residential homes to apartments complexes to state prisons. Everday is different in my line of work, sometimes I'm chasing my tail trying to find a lose neutral, while other days I'm installing an electrical panel for a tiny home. My family and I moved to Piedmont about two years ago and have been enjoying getting to know the upstate's beautiful natural resources and charming cities. I look forward to meeting you and working with you on your next electrical project.

"Great communication from Greg. Will be referring him to friends and I will rehire for my next electrical job!"

FAQs for generator installation projects in Simpsonville, SC

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
