"Lighthouse Restoration Group replaced and upgraded my electrical service — two new panels, 400 amps total — and it’s by far the cleanest install I’ve seen across all the upgrades and repairs we’ve done at our house. The before photo shows the dangerous and sloppy work that accumulated by probably dozens of different electricians. These guys saw this and were appalled. Now see the after. Every wire is perfectly routed, tensioned to spec, and labeled. It looks like something out of a training manual. What really stood out wasn’t just the craftsmanship but the professionalism. They checked every single outlet, light, and appliance in the house — not “most,” not “some.” Every one. They even torqued each lug exactly to manufacturer spec. No shortcuts, no guesswork. They’ve got pride in their work, and it shows. If you actually care about doing things the right way — not just “getting it working” — these are your guys. I’d hire them again in a heartbeat."

Cost is determined by the job. Call 630-809-9111 for all of your electrical needs. We service portions of Will and Dupage County.

"In January 2023, Steve Durkiewicz stepped into a project that had previously become a financial nightmare and turned it into the dream project that we had first imagined. We had previously hired and paid ($1,765.00) a different person/business that claimed to be a licensed and experienced electrician, to install new lighting in our kitchen and home office, as well as install recessed lighting in our family room. But the job was a disaster, unprofessional and substandard - e.g. all electrical wiring was incorrect, ceiling drywall wire routing in relation to studs/framing was incorrect (i.e. ceiling drywall could not be repaired due to lack of space), etc. Steve came in and repaired all of that. With patience and professionalism, he explained every step as he made corrections, and still completed the task in a timely manner! Thank you, EMF Electric! You'll definitely hear from me again!"

We're a family-owned and operated business with more than 15 years under our tool belts! We take on a wide range of electrical services from remodeling to new projects, even repairs! No job too small, no job too big! We’re committed on providing a personalized service for each individual project we take on! ***Call/Text : 1(630)915-8938 OR Email: [email protected]***

"I had an overloaded kitchen circuit shoot fire through a receptacle (and melt the whole thing down) a few days before I went on a European trip. I managed to use extension cords to keep my kitchen going until I returned. I had notified several companies before I left but I did not understand what "Flat Pricing" meant. BoBo contacted me directly through an email I supplied on the Next Door app and I arranged for their services when I returned. Two young fellows arrived on time with all the equipment needed. They assessed my problem and offered several solutions and quoted prices for each one and I just said: "What would you do if this were your house?" They "split" (re-wired) the overworked circuit into 3 separate dedicated lines, provided me with 3 GFI receptacles for the kitchen and replaced all of the mis-matched circuit breakers in my electrical panel. They were an awesome team to watch: knowledgeable, efficient and they worked quickly"

Generator Install questions, answered by experts

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. 

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator.
