kohler vs generac whole house generator


As a homeowner, nothing is more frustrating than experiencing a power outage. Not only does this disrupt your daily routine, but it also poses a risk to your home and family’s safety. This is where whole house generators come in handy. These devices provide backup power during an outage to keep all your appliances and electronics running smoothly. In this review, we’ll be comparing two popular brands – Kohler and Generac.

Section 1: Kohler Whole House Generators

Kohler offers a range of whole house generators to cater to different needs. The Kohler 20RESCL-200SELS is their most popular model, capable of powering a 5,000 square foot home. Their generators use a patented technology called PowerBoost that allows the unit to start large loads like air conditioners without dropping power.

Kohler generators are known for their reliability and quiet operation. They come equipped with an automatic transfer switch that switches the generator on within 10 seconds of a power outage, ensuring that your home’s power supply is never disturbed.

However, Kohler generators are known to be more expensive than their competitors. They also require professional installation, which adds to the overall cost.

Pros of Kohler Generators

  • Reliable and quiet operation
  • PowerBoost technology allows the device to start large loads without drops in power
  • Automatic transfer switch ensures prompt backup power

According to customer reviews, Kohler generators have a 4.7 out of 5-star rating, with many customers praising their reliability and ease of use.

Section 2: Generac Whole House Generators

Generac is another household name when it comes to whole house generators. One of their most popular models is the Guardian 22kW generator, which can power an entire home for days during an extended outage.

Generac generators are known for their ease of use and low maintenance. They come equipped with a digital controller that manages the power output, ensuring that all appliances run smoothly. Additionally, Generac generators offer a 5-year limited warranty, giving homeowners peace of mind.

On the downside, Generac generators are known to be noisy during operation. They also do not have PowerBoost technology like Kohler units.

Pros of Generac Generators

  • Comes with a 5-year limited warranty
  • Offers a range of whole house generator models to meet different needs

Ultimately, the brand that suits your needs depends on the size of your home and the appliances you need to power. Kohler generators are better suited for larger homes with more appliances, whereas Generac generators are ideal for smaller homes.

What size whole house generator do I need?

The size of the whole house generator you need depends on the size of your home and the appliances you want to power during an outage. A typical 2000 sq. ft. home will require a 20-22 kW generator to power all of the essentials. However, if you have a larger home or a lot of high wattage appliances, you may need a larger generator. It’s best to consult with a professional to determine the right size generator for your specific situation.

Yes, whole house generators require regular maintenance to ensure they are in proper working order. This may include changing the oil and filter, cleaning the air filter, checking the spark plugs, and inspecting the battery. It’s important to follow the manufacturer’s recommended maintenance schedule to keep your generator running smoothly and prevent unexpected issues during an outage.

How long do whole house generators last?

The lifespan of a whole house generator depends on several factors, including the quality of the generator, how often it is used, and how well it is maintained. A well-maintained generator from a reputable brand such as Kohler or Generac can last up to 20-30 years or more.

Can I install a whole house generator myself?

It is recommended that you hire a professional to install a whole house generator.
