"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

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
