Challenges and Considerations

No product is perfect. Here are a few practical considerations to weigh:

Initial Cost

  • Kohler generators tend to be more expensive than comparable Generac models. Expect to pay a premium for the build quality and reputation.
  • Generac offers more entry-point models, but install costs (including transfer switches and wiring) still add up.

Maintenance and Parts

  • Generac’s extensive dealer network means parts and service calls are typically faster and less expensive.
  • Kohler’s specialized components may result in slightly longer wait times or higher parts costs, especially in remote areas.

Installation Requirements

  • Both brands require professional installation for warranty coverage and local code compliance.
  • Ease of installation will depend on your home’s layout, fuel availability, and panel compatibility. Most local dealers are equipped for both brands.

Power Management

  • Larger homes may require advanced load management systems. Kohler systems excel at balancing heavy or sensitive electrical loads.
  • Generac’s load-shedding modules help maximize usage during an outage but may not be as robust for very large properties.

Practical Tips and Best Practices

1. Assess Your True Power Needs

  • Make a list of the circuits or appliances you absolutely need during an outage.
  • Sizing your generator too small leads to frustration; buying a model that’s too big is an unnecessary expense.

2. Consider Your Location

  • If you live in a region prone to frequent or lengthy outages, invest in a generator with a proven reliability record.
  • Coastal or extremely cold climates should look for models with special weatherproofing and cold-start features.

3. Plan for Maintenance

  • Regular maintenance (oil changes, spark plugs, battery checks) keeps your generator ready for emergencies.
  • Join a maintenance plan through your installer or manufacturer for hassle-free service reminders and support.

4. Prioritize Easy Monitoring

  • Modern systems offer smart controls and remote monitoring. These features can notify you of issues before an outage hits.
  • Keeping track remotely saves time and helps prevent last-minute surprises.

5. Installation and Permitting

  • Always hire a licensed, experienced installer. Improper installation can void your warranty and create safety risks.
  • Check local permitting requirements and HOA rules before committing to a purchase.

6. Fuel Storage and Backup

  • Ensure adequate access to your chosen fuel. For propane, keep tanks filled and schedule regular deliveries.
  • Periodically check connections and tanks for leaks or corrosion.

Cost-Saving Tips (Including Shipping Considerations)

  • Shop Locally: Buying from local dealers often means lower shipping costs and easier service in case of warranty repairs.
  • Compare Multiple Quotes: Get estimates from at least three installers to balance generator price with shipping and labor costs.
  • Seasonal Promotions: Manufacturers and dealers often offer discounts or free shipping during storm-preparation seasons.
  • Buy with Installation Included: Some installers bundle installation, delivery, and inspection fees—often cheaper than paying for these separately.
  • Understand the Fine Print: Warranty and returns may be affected by shipping distance or who performs the installation—always clarify before you buy.

Summary: Which Brand is the Best Choice for You?

Choosing between Kohler and Generac ultimately comes down to your personal needs, priorities, and budget:

  • Choose Kohler if ultimate reliability, quieter operation, and premium build quality are paramount, and you don’t mind paying a bit more up front.
  • Choose Generac if you’re looking for a solid, budget-friendly home standby generator with easy access to parts, service, and user-friendly features.

Both brands will keep your lights on and appliances running in a crisis—you’re really picking between excellent and great. Evaluate your power needs, weigh local support options, and invest in a generator that will give you peace of mind for years to come.
