With 21 years experience I specialize in all residential and commercial electrical needs. Past jobs include kitchen and bath remodels, basement build outs, new construction and home theater / media rooms. Safe reliable and fair competitive pricing. No job is too small. Servicing: Naperville, Plainfield, Aurora, Shorewood, Bolingbrook, Romeoville, Downers Grove, Wheaton, Hinsdale, Burr Ridge, Elmhurst, Lombard, Glen Ellyn, Joliet & New Lenox.

"Let me start out by saying that I would definitely use Custom Power Electric again, and would highly recommend to friends and family. My project was to have four flush ceiling lights installed in a small office and a single flush ceiling light above a bathroom tub. Neither of these installations were easy. The fixtures would need to be install near the edge of the roof leaving little room to work. I contacted an electrician that I had used in a prior project who promised to come out and give me an estimate, but never called back. I then contacted another electric company who told me their dollar per hour rate, indicated that the job would probably take 8 hours and I would need to buy the light fixtures and switches. This approach bothered me in that if I pick up something that’s incorrect then I would need to rush out while the electrician was on site, wasting time. When I contacted Custom Power Electric, I discussed the project with Rich Mohlman the owner, exchanged a few text messages and photos and was provided with a cost almost immediately that included all of the fixtures and materials. Rich’s price was close to the other company where I needed to furnish the fixtures. When I accepted his price I got an installation date within hours that was only a week away. When Rich arrived, he covered the work areas in drop cloths to protect our furnishings and alleviate leaving a construction mess. Rich finished the job in 4.5 hours including clean-up, and the wife and I couldn’t be happier with the job."

Generator installations FAQs

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 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.

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
