When the power goes out, a reliable home generator can be a lifesaver, keeping your essential appliances running and your home comfortable. Two of the most trusted names in the generator industry are Kohler and Generac. Both brands offer high-quality standby generators, but they cater to slightly different needs and priorities. In this blog post, we’ll compare Kohler and Generac home generators based on key factors like reliability, features, noise levels, cost, and more to help you decide which is the better choice for your home or business.

Company Background

Kohler

Kohler, founded in 1873 and producing generators since 1920, is one of the oldest names in the industry. Based in Wisconsin, USA, Kohler is renowned for its premium build quality and innovative technology. With over a century of experience, Kohler generators are often praised for their durability and reliability, making them a top choice for homeowners seeking long-term peace of mind.

Generac

Generac, established in 1959, is also based in Wisconsin and has quickly become a market leader in residential generators. Known for competitive pricing and innovative features, Generac holds a significant share of the home generator market, often appealing to budget-conscious consumers who still want reliable performance.

Key Factors to Consider

Reliability and Durability

Reliability is the top priority when choosing a generator, as it ensures your home stays powered during outages.

• Kohler: Kohler generators are celebrated for their robust engineering and longevity. Their Command PRO OHV engine is designed for both residential and commercial use, offering exceptional durability. Many experts and homeowners report that Kohler models tend to outlast competitors, with lifespans often exceeding 30 years with proper maintenance. Kohler’s reputation for reliability is bolstered by its use of high-quality materials and rigorous testing, including in extreme conditions like South Pole expeditions.
• Generac: Generac generators are also reliable, particularly their models with the purpose-built G-Force engine, which is designed for rigorous use and requires less routine maintenance. Generac’s durability is enhanced by their RhinoCoat powder-coated finish, which protects against corrosion. However, some users and technicians note that Generac’s reliability may not match Kohler’s in the long term, especially for heavy-duty applications.

Winner: Kohler has a slight edge for long-term reliability and durability due to its longer history and premium build quality.

Features and Technology

Both brands offer advanced features to make their generators user-friendly and efficient.

• Kohler:
  • Remote Monitoring: Kohler’s OnCue Plus system allows you to monitor and control your generator via smartphone or computer, though it may require additional costs.
  • Automatic Transfer Switch: Ensures seamless power transition during outages.

  • Exercise Options: Offers three modes (unloaded low-speed, unloaded full-speed, and loaded exercise) for flexible self-testing, with adjustable run times.
  • Sound-Dampening Enclosures: Kohler generators are known for their quiet operation, often compared to an air conditioner, thanks to pre-installed sound-dampening enclosures.
• Generac:
  • Remote Monitoring: Generac’s Mobile Link™ system provides free remote monitoring, allowing you to check generator status via smartphone or tablet.
  • Automatic Transfer Switch: Like Kohler, Generac ensures quick and seamless power transitions.
  • Power Management: Includes advanced power management to distribute power efficiently without overloading.

  • PWRview App: Offers insights into energy usage, helping optimize power consumption.
  • Multilingual LCD Display: Enhances ease of use by displaying maintenance intervals and battery status.

Winner: Generac takes the lead in technology due to its user-friendly features like free Mobile Link™ and the PWRview app, which add value without extra costs.

Noise Levels

For residential use, a quiet generator is essential to avoid disturbing your household or neighbors.

• Kohler: Kohler generators are praised for their low noise levels, often operating at sound levels similar to an air conditioner (around 64–69 dB during testing or full power). Their sound-dampening enclosures make them a top choice for noise-sensitive environments.
• Generac: Generac has made strides in reducing noise, particularly with its Quiet-Test™ mode, which operates at lower RPMs during self-tests. However, some models may be slightly louder than Kohler’s, especially air-cooled units running at higher RPMs (up to 3600 RPM).

Winner: Kohler is generally quieter, making it ideal for neighborhoods or homes where noise is a concern.

Cost and Value

Budget is a significant factor when choosing a generator, as both the unit and installation can be pricey.

• Kohler: Kohler generators are typically more expensive, with prices for a 20kW unit starting around $14,570, including installation. Their premium build and longer warranties (5-year/2,000-hour standard, with optional 10-year extended warranties) justify the higher cost for those prioritizing longevity.
• Generac: Generac is known for its competitive pricing, with a 24kW unit costing around $15,476 after rebates, and smaller units ranging from $2,049 to $17,569. Their standard warranty is 5 years, with optional 10-year extensions, but their lower upfront cost makes them appealing for budget-conscious buyers.

Winner: Generac offers better value for those seeking affordability without sacrificing core features.

Warranty and Customer Service

A strong warranty and reliable customer service are critical for peace of mind.

• Kohler: Offers a 5-year/2,000-hour warranty, with optional 10-year extended warranties. Kohler’s customer service is highly regarded, with a network of certified dealers providing support. However, some users report that Kohler’s warranty process can be complex, requiring technical expertise to navigate.
• Generac: Provides a 5-year limited warranty, with optional 10-year extensions. Generac’s customer service is available 24/7, and their wide market presence ensures easier access to parts and technicians. Some users note that Generac’s warranty process is more straightforward.

Winner: Generac has a slight edge due to its widespread availability of parts and simpler warranty process.

Enclosures and Environmental Resistance

The generator’s enclosure protects it from weather, pests, and corrosion, especially in harsh climates.

• Kohler: Offers a variety of enclosures, including corrosion-resistant aluminum and composite options, ideal for coastal areas with salty air. Their enclosures are non-flammable, though plastic options require careful placement to avoid fire risks.
• Generac: Features powder-coated steel or aluminum enclosures with RhinoCoat finish for corrosion resistance. These are durable and non-flammable, making them suitable for various environments.

Winner: Kohler offers more enclosure options, giving it a slight advantage for specific environmental needs, like coastal regions.

Fuel Efficiency and Power Output

Fuel efficiency and power output determine how long a generator can run and what it can power.

• Kohler: Known for excellent fuel efficiency, especially in larger models, and offers a range of power outputs (up to 26kW for residential use). Their Power Boost technology provides extra power during startup for high-demand appliances.
• Generac: Also fuel-efficient, particularly with the G-Force engine, and offers a wide range of power outputs (7kW to 60kW). Generac’s True Power™ technology ensures clean power for sensitive electronics. Note that gaseous-fueled models may see a 10% power reduction on natural gas compared to propane.

Real-World Feedback

• Kohler: Homeowners and experts often praise Kohler for its longevity and quiet operation. However, some note that parts can be expensive and harder to source, and there have been isolated reports of issues with composite frames in older models (no longer manufactured).
• Generac: Generac enjoys a strong reputation for affordability and ease of maintenance, with many users reporting reliable performance during extended outages, such as during hurricanes. However, some technicians and users express concerns about long-term reliability compared to Kohler, and there are occasional complaints about electronic board issues.

Which Generator Is Right for You?

Choosing between Kohler and Generac depends on your priorities:
