“I own a Kohler generator that I bought through Kohler. Having a home generator is definitely a premium. I've had one for 15 years. I have a well water all the time and it is pretty high on my priority list. Having a generator for it makes me the happiest.
Being an electrical contractor, I'm exposed to a lot of different other brands and Kohler is a standout. It's a great product and their quality is really good. They recently changed hands as a corporation so I'm still waiting to see how that works out. Other than that, excellent products and excellent parts availability.”

"We researched and KOHLER appeared to be the best generator, even though Generac, produces more. It’s of a higher quality. We've used it once since we had it installed in July. We lost power for 20 minutes. It has been seamless. You can't even tell.
And every week we do a test, the generator kicks on for 20 minutes. The time there was an issue, they came out, because we have a warranty. They figured out what the issue was, and they fixed it. We haven't had any problems since. We feel that we are protected. Our pets are safe.
We are safe. It has been a wonderful experience." Reviewed May 4, 2026
Home Generator FAQs
The total cost of a standby home generator depends on several factors, including:
Generator size and power capacity
Whole-home vs essential-circuit coverage
Natural gas or propane setup
Electrical and gas line work
Permits and site preparation
Installation complexity
Because every home is different, most homeowners schedule a free site evaluation to receive a custom recommendation and quote. A certified dealer can assess your home’s power needs and installation requirements before providing pricing.
Most standby generator installations are completed within a few days once equipment and permits are ready. The overall process can take longer depending on:
Permit approvals
Utility coordination
Generator availability
Weather and site conditions
Gas or electrical upgrades
Yes — financing is commonly available through many authorized dealers.
Yes — a standby generator is specifically designed to start automatically even if you are away from home. When utility power is lost, the generator’s automatic transfer switch (ATS) detects the outage, signals the generator to start, and transfers your home’s electrical load to backup power — typically within about 10 seconds. Once utility power returns, the system automatically switches back and shuts the generator down.
