"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!!"

Generator Install questions, answered by experts

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.
