"I cannot say enough great things about Jamie and the team at Wisconsin Generators LLC. From the very first conversation, Jamie was professional, knowledgeable, and incredibly responsive. He took the time to walk me through all my options, answered every question thoroughly, and made sure I felt confident in the decision we were making. The installation process was seamless. The crew showed up on time, worked efficiently, and treated our property with respect. Their attention to detail and commitment to doing the job right was obvious from start to finish. Everything was clean, organized, and completed exactly as promised. What really sets Jamie apart is his integrity and customer-first approach. There was no pressure just honest recommendations and clear communication. If you’re considering a standby generator, I highly recommend Jamie and Wisconsin Generators LLC. Reliable service, expert installation, and true peace of mind. Five stars all The way!!"

"I would recommend Current Electric to anyone! They are affordable, professional, and customer service oriented. We had Eric as our electrician and he went above and beyond for us. We had a new outlet installed, can lights installed, and ceiling fans installed. He kept us informed the whole time with updates on progress, time frames, and got our input along the way. We will definitely be using Current for all of our electric needs."

"Needed to hook up my portable generator to the house. Mr Sparky was the first to call from angi so I asked for a quote. They came over very quickly and gave my wife and I a very good quote we thought. We didn't even get another, Slept on it, they called back the next day and we set set up a date. Mario showed up (very nice guy) . Said it would be a couple hours, and it was. They didn't need to turn off the whole house which was good and wired in a new electrical panel and plug on the outside. We tested it, and it worked perfectly. We are very happy. Thanks guys....!"

"Jim was very fast at coming to evaluate what we all needed to have done. He did a great job and cleaned up after he was finished. While he was here we had an issue come up for another electrical problem and he ordered the part and came back as soon as he got the part. Will definitely hire him again when we need electrical work."

"All of their technicians were very professional and polite and helped me understand what was going on every step of the way, from the initial inspection, diagnosing the issue, deciding on a new furnace, and through the installation process. When the inspection showed that my furnace was no longer working, they even shuffled some appointments around to make sure I had working heat before it started getting too cold outside. Not only did they do a great job installing the new furnace and AC, they went out of their way to clean up the basement and duct work a bit and left things looking even better than when they got there! Mike was my technician for the initial inspection and Austin worked on the Furnace and AC install. There were a couple other techs with them as well who's names I didn't quite catch, but all of them were great!"

"Tony installed soffit lights in our home and garage. We couldnâ t be happier with the results. Work was performed with the utmost professionalism and courtesy. He even took the time to completely explain how to use an app to control the lights installed. We would highly recommend Freedom Electric."

"I hired them for some electrical work at my home and was impressed right away with how straightforward and honest they were. The pricing was very fair compared to other quotes I received, and they took the time to explain exactly what I was paying for so there were no surprises. The technician arrived on time, worked efficiently, and clearly knew what he was doing. Everything was completed to a high standard, and you can tell they focus on doing quality work rather than cutting corners. It’s not easy to find someone who balances good pricing with solid workmanship, but they nailed both. Overall, great value for the money. I’d definitely recommend them to anyone looking for dependable service at a fair price, and I wouldn’t hesitate to call them again."

Generator Install questions, answered by experts

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. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.
