"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!!"

"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!"

"They did a great job. Very efficient and had great communication. When something came up we were made aware of it and it was also taken care in a timely fashion. Dorow's team made sure that everything was completed and met the criteria. Once the work was completed they made sure we had all documents needed for the inspector and once the inspector did the inspection and if anything needed to be added Dorow's crew made came out and added the necessary components. Overall very satisfied with a job well done!"

"First, they were recommended to us for the whole house generator by home depot.  We were so happy with the generator that we had him do a bathroom fan at my house and a bathroom fan at my son's house.  I did some checking and that was a reasonable price.  With the work he did, it was more than reasonable.  The job was a little more involved than he thought it would be and he didn't have any problem with any of it.  Without anything to judge the pricing from, other than online and a couple of guys I had come over who weren't on the same page as me, I'd say excellent.  The quality was top of the line.  As soon as he got the generator, he got over here to put it in. As a matter of fact, I am thinking about calling him again for something."

Generator Install questions, 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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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.
