"I'm very satisfied with his work. I had used him for 16 years and I had him install two different generators. I never had any problems at all and he is very responsive; that is why I have recommended him before."

"I am in process of a deck build. The company involved (Wooddale,Il.) indicated they use a third party electrician that was not affiliated with the deck company, but they utilize their services when need. When I inquired during the build when I would be contacted by electrician, it seemed the build company dropped the ball by not scheduling the electrician. Alex, of Power Electric, Wheaton, Il. is the electrician who when contacted, immediately responded. He came on Tuesday, looked at my needs in the project and gave me a price range due to some 'possible' install issues within the home. because the project manager lacked on scheduling, I asked Alex when he could schedule the job since the installers were ready to start putting the deck boards on the frame. Alex, was AMAZING!!! He scheduled the job two days later. What first grabbed my attention, was Alex's personality- very personable, likeable, positive, etc. If you're a people person, you'd understand. His work is precise and clean. He and his partner (dad) wore booty's or removed shoes inside the house. They worked well together making job go smoothly. Alex took the time to lable the breaker, show me the outlets and what to troubleshoot if needed. And also what to show the installers in order to complete deck. Alex is a people person, dedicated to the customer. I would not only recommend Alex and Power Electric (Wheaton, Il.), I will use them for any furture electrical project in future. Thanks Alex."

"Ariel installed 50 amp inlet to my breaker box for portable generator. He completely cleaned up the breaker box. Separated rooms to different breakers so I can turn off rooms i don't use. He was extremely thorough in his work. Upon finishing installation, Ariel stayed on his own time and explained everything i needed to know about using generator and which breakers to use if i have a power outage. He was very knowledgeable and made sure i understood before he would leave. I highly recommend ACG based on my experience with his work ethic. Thank you Ariel!"

"Colin and his team were able to install a charger in my garage which required a long external run with many turns. They measured and quoted very clearly, and showed up with all supplies needed to do the job the next day. They were super professional and I would highly recommend them."

Generator Install FAQs, answered by experts

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
