Kohler 20RESCL-100LC16 Air-Cooled Standby Generator Review

by Charles Jasper

Product Overview

Kohler 20RESCL-100LC16 Air-Cooled Standby Generator is a moderately priced product that is worth consideration when searching for a new home generator. Known for its reliability, this generator is one of the best in its class. Many high-risk facilities have put their trust in this generator, including hospitals, airports, and more.

The item is 515 pounds and 120 volts, and the dimensions are 48 x 26.2 x 29 inches. The generator by itself costs a little over $4,600, but after paying for shipping and installment materials and labor, the total comes out closer to $10,000. It is certainly a large home improvement investment, but with its good reviews and high ratings, this product deserves to be on your list of potential candidates when considering standby generators for the home.

The Kohler 20RESCL-100LC16 has many great features, but it is not without faults. It is important to look thoroughly at the pros and cons before making such a large decision. Home generators are a large investment, and you should make sure that you’re making the best decision you can. First let’s look at what this product has to offer.

Main features

This model was designed for easy installation. As with many of its competitors, the manufacturer, Your Other Warehouse – Lawn and Garden, realized that easy installation is important to buyers. A complicated installation process leads to a higher chance of error as well as higher installation costs.

The Kohler 20RESCL-100LC16 Air-Cooled Standby Generator is designed exactly for this purpose. It has a hinged top that is easy to lock, and its base doesn’t require a cement mounting area beneath it. There is also easy access to the wiring in case anything was to go wrong.

The generator has a powerful performance as well. It’s designed to allow other big appliances at the same time without running into major issues. This is unusual for home generators, and is an advantage of this particular model.

The generator is also built to withstand extreme weather. The corrosion-proof exterior allows from the technology inside to stay on top of providing electricity to your home when you need. This means less issues, which leads to less maintenance costs and a longer lifespan.

This generator also senses when the power is out and turns itself on. The power will be back on in your home within ten seconds or less. This saves a lot of time and hassle for the homeowner, and it turns a major inconvenience (the power going out) into a very minor one (having to wait ten seconds for the lights to turn on).

Is it reliable?

When buying a home generator, the big question you are probably asking is, “is it reliable?” This model seems to have mixed reviews in that regard. Many users claim that they have been using the Kohler 20RESCL-100LC16 for many years without one problem. Others seem to have a different experience.

Some users claim that this generator failed within a few days, or even within 20 minutes of running. While the unsatisfied users are in the minority, this is unfortunately not an uncommon response. This product seems to have racked up more than a couple large repair bills, which have left the customers rethinking their choice of product.

Additionally, when having these issues, buyers seem to have a hard time getting technical support quickly. Although Kohler does offer services and repairs (at a price, of course), they tend to not be the quickest in response time. Owners of this generator often must wait weeks or even months before their product is serviced, and even then, many people have complained about long-term issues resurfacing.

Even those who were satisfied with their purchase had issues contacting Kohler. Even for simple matters, such as a question about installation, the company seems to be generally unreachable and does not return calls. This could lead to some major issues down the line, as even small issues could lead to big charges from technicians who know far less about the product.

After getting serviced by Kohler, some customers mentioned that they were billed unusually high amounts for unusually small issues. One owner claimed that he had to pay $1400 to replace a single part in the generator after the warrantee had just expired.

Although this group of unsatisfied customers is in the minority, there are a significantly larger percentage of negative reviews when compared to Kohler’s competitors. The supporters of the product though, boast about how wonderful the product is and highly recommend it to anyone looking to buy a home generator themselves.


  • Automatically turns on in an outage
  • Corrosion-proof exterior
  • Low maintenance over long-term usage
  • Reasonably priced
  • Low noise levels
  • Powerful performance that allows to run other large appliances


  • Outdoor installation only
  • Only a 5-year warrantee (less time than most of its competitors)
  • Less reliable than its competitors
  • Slow customer service


The Kohler 20RESCL-100LC16 Air-Cooled Standby Generator may not be the most reliable or favored product overall, but it does offer a lot to its users and is reasonably priced. Although the generator may seem ideal from its ads and features, be wary of the many issues that users have had before you. The Kohler 20RESCL-100LC16 is a great option for a long-lasting, reasonably priced, fairly quiet generator.

Don’t let all the negative comments scare you away, but do be aware of what may go wrong and what other costs might accompany a purchase of this model.
