"It went very well. House phone wiring was traced and rewired to connect fax machine to new Xfinity VOIP line on a different floor. This will save me ~$70/month in AT&T telephone charges. Flowing Through Connections arrived on time and completed the work in about 2 hours (including time to clean up some of the wiring work I tried to do myself). Price was very reasonable."

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!"

AZ Electrical Co. is a family owned electrical contractor based in Glendale Heights, IL. We pride ourselves on high quality craftsmanship, ethical treatment of customers and getting it done right the first time. 15 years of experience. Our installations are only according to NEC standards. Installations of breaker panels, dedicated circuits, receptacle outlets, lights, etc. For fastest response, please call, text or email.

"AZ Electrical was one of the contractors Home Depot suggested to install an attic fan for us. We received four quotes and all were in a similar price range. AZ's stood out for it's thoroughness. Art asked questions and explained the options versus two quotes that were about 30 seconds long and just a flat cost. Art brokedown the cost and gave options for the amount of air each of the three fans could move. Given the was only a $50 spread of the three options, we chose the fan that moved the most air. The day of the install, Art arrived promptly and the install went quickly. In addition to quality work done relatively quickly, the quality of fan Art used was great. Our previous attic fan had always been loud enough you could hear it running in the background. This fan? Quiet enough I hear only when I open the attic. And as Art recommended, the fan moves a lot of air. As I open the attic door, you can feel air being pulled into the attic. Since then, our upper level has stayed cooler than it's been in years. AZ Electrical does high-quality work quickly. Will definitely use AZ in our future projects that require electrical work."

Generator Install questions, answered by experts

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
