"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!!"

"This is the third time we've had him for various electrical jobs and all have been exceptional experiences.  He is prompt, efficient and thorough in his work.  I called him on Sunday and he was able to fit this small job in the next day so we could do laundry again.

"There is no air conditioning on the first floor of the non-profit house for which I am Property Director.  With the donation of and installation of a window AC unit, it was suggested that a ceiling fan in the living room (where the AC unit was installed) would help circulate the cool air.  I had worked w/Horizon Electric previously for electrical repairs, but not for an installation requiring new wiring, etc.  The owner, Lee, met me at the house within a few days and almost immediately found a way to wire in a new ceiling fan in the living room.  With further discussion we decided a ceiling fan w/lights would also be worthwhile in the dining area.  In that case he had to extend wiring to this adjacent room and, again, came up with a solution.   He quoted me a price for the installation of the living room fan only and another for the installation of both fans.  
With Board of Directors approval I was able to get back to him within the week and the following week both fans were installed. Even though Lee had told me that his workload was out 2-3 weeks, he understood the importance of getting these fans installed 
and that was done in record time.  The House Manager reported to me that the workman finished the installation of the fans we provided in one day, as promised, and, even with the house residents present (including young children), left nothing lying about that could be hazardous to anyone, was efficient and cleaned up the work area thoroughly after he was done.
We were billed the amount quoted.
I would definitely use this company again and highly recommend it.

"Excellent work! Project involved running 100A service from house to detached garage, running power to equipment, and installing outlets. Happy with the price and was impressed with the work, so I decided to expand the scope - am having him come back to put in some more circuits. I have hired a number of contractors over the years, including at work for some involved projects. Marty is up there with the best: great communication, personable, completed the work sooner than I expected, and his experience shows - around 15 years, including industrial and commercial experience. He recently started his own business."

Generator Install questions, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.
