Whole Home Generators

Determining the size of your generator depends on your home’s power requirements. Follow these steps:

1. List Essential Appliances: Include refrigerators, HVAC, sump pumps, and lights.
2. Calculate Starting Wattage: Check the starting and running wattage of each appliance. Starting wattage is often higher for devices like air conditioners.
3. Add Up Total Wattage: Use a generator sizing calculator or consult a professional to ensure the generator can handle the total load.
4. Consider Future Needs: If you plan to add appliances or expand your home, factor in extra capacity.

A general guide:

• 7-10 kW: Essential appliances and lights.
• 12-20 kW: Whole-home power for average-sized homes.
• 20-25+ kW: Large homes with high energy demands.

The lifespan of a home generator depends on its usage and maintenance:

• Average Lifespan: 10–30 years or 10,000–30,000 hours of operation.
• Factors Affecting Lifespan:
  • Regular maintenance, including oil changes and filter replacements.
  • Quality of the generator and brand reputation.
  • Frequency of use—standby generators last longer than portable ones used regularly.

Tip: Schedule annual maintenance to extend the life of your generator.

Installation costs vary depending on generator size, brand, and labor requirements:

• Generator Cost: $3,000–$10,000, depending on size and brand.
• Installation Cost: $2,000–$5,000 for professional installation, including electrical work and permits.
• Total Cost: $5,000–$15,000 on average.

Factors influencing cost:

• The complexity of electrical connections.
• Distance from fuel sources (natural gas line or propane tank).
• Additional features like automatic transfer switches.

Generac generators are among the most popular for several reasons:

• Reliability: Generac is known for dependable standby power solutions.
• Cost-Effectiveness: They offer a range of models to fit different budgets.
• Automatic Transfer Switches: Seamless power restoration during outages.
• Wide Availability: Replacement parts and service technicians are easy to find.
• Warranty: Generac offers competitive warranties on most models.

While Generac generators are reliable, there are some drawbacks:

• Noise Levels: Some models are louder than competitors like Kohler or Cummins.
• Maintenance: Regular maintenance is critical to prevent issues, and skipping it can lead to failures.
• Load Capacity: Smaller Generac models may not support large homes or high-wattage appliances.
• Initial Setup Costs: While affordable upfront, professional installation can increase costs.

For a 2,000-square-foot home, the recommended Generac generator size is typically between 12–22 kW, depending on your power needs.

• 12–14 kW: Covers essential appliances and systems, like refrigerators, HVAC, and lighting.
• 16–22 kW: Provides full backup power for the entire home, including additional devices like a water heater or electric stove.

Consult with a professional to determine your specific requirements based on the appliances you want to power during an outage.

Recent controversies around Generac generators have involved:

• Safety Concerns: Reports of faulty components, such as their automatic transfer switches, have led to lawsuits and recalls.
• Customer Service: Some users have expressed dissatisfaction with delayed customer support during warranty claims.
• Noise Complaints: Generac models have been criticized for being noisier than competitors.

Despite these issues, Generac remains a leading choice due to its reliability and innovation in generator technology.

Kohler and Generac are both reliable brands, but they excel in different areas:

• Kohler Advantages:
  • Quieter operation compared to Generac.
  • Known for robust engineering and long lifespans.
  • Offers corrosion-resistant enclosures, ideal for coastal areas.
• Generac Advantages:
  • More affordable options for budget-conscious homeowners.
  • Easier to find parts and service technicians.

Verdict: Kohler may edge out Generac in reliability for long-term durability and quieter operation, but Generac offers better value and accessibility.

The most reliable generator brand depends on your specific needs, but top contenders include:

• Generac: Best for cost-effectiveness and accessibility.
• Kohler: Best for quiet operation and durability.
• Cummins: Known for heavy-duty and commercial-grade reliability.
• Briggs & Stratton: Affordable and reliable for smaller homes.

Choosing the Right Brand:

• For overall performance and value: Generac.
• For quiet and durable systems: Kohler.
• For high-output needs: Cummins.
