How to Choose the Right Generator for Your Home

April 24, 2025

One Call Does It All

When the power goes out, you need to be prepared. A generator ensures that your home stays comfortable, safe, and powered even during outages. But with so many options on the market, choosing the right generator can be overwhelming. Whether you're looking to power your entire home or just the essentials, it's important to make an informed decision.

At Roth Home, we are committed to providing eco-friendly, reliable solutions for Oregon homeowners. With more than 48 years of experience and a dedication to sustainability, we help you find the right generator that suits both your needs and your values. This guide will walk you through the process of selecting the best generator for your home, from understanding your power needs to choosing the right fuel source.

Step 1: Understand Your Power Needs

The first step in choosing a generator is determining what you want to power during an outage. Do you need to keep the essentials running, or do you want to maintain your whole home’s functionality? Knowing this will help you decide on the appropriate size and type of generator.

Essential Power Only

For some homeowners, keeping the basics running during an outage is enough. A small generator can power essential appliances such as:

  • Refrigerator/freezer
  • Lights and Wi-Fi
  • Medical equipment
  • Security systems

This is a more affordable solution for those who want peace of mind but don’t need to power the whole home during outages.

Full-Home Backup

If you want to maintain normal living conditions during an outage, a whole-house generator is the best option. This type of generator can power your entire home, including:

  • HVAC systems
  • Kitchen appliances
  • Water heaters
  • Electronics

Roth Home’s No Breakdown Guarantee gives you confidence in your choice. If something goes wrong with the generator, we’ll come back and fix it at no extra cost, ensuring your home stays powered when you need it most.

Step 2: Choose the Right Fuel Type

Generators come in several fuel types, and your choice depends on your location and preferences. Each fuel type has its pros and cons, and Roth Home’s eco-friendly practices ensure that the fuel options we recommend are both efficient and sustainable.

Natural Gas

Natural gas generators are connected to your home’s existing gas line. They offer the convenience of continuous power with no need to refuel manually.

  • Ideal for: Homes connected to natural gas lines
  • Benefits: Continuous supply, lower emissions, no need for refueling

Propane

If you don’t have access to natural gas, propane is an excellent alternative. Propane generators are reliable and can store fuel for long periods without degradation.

  • Ideal for: Homes in rural areas or those without natural gas access
  • Benefits: Longer shelf life than gasoline, cleaner-burning, easy to store

Diesel

Diesel generators are powerful and durable, making them ideal for large homes or commercial properties. Diesel tends to be less environmentally friendly but provides excellent performance.

  • Ideal for: High-demand applications or large properties
  • Benefits: High power output, fuel-efficient

At Roth Home, we strive to help you make an eco-conscious choice that balances your power needs with our commitment to sustainable practices, like using equipment that reduces waste by up to 98%.

Step 3: Select the Proper Size

Generator size is one of the most important factors to consider. A generator that’s too small won’t be able to handle your home’s power needs, and one that’s too large will waste energy and fuel. Choosing the right size ensures that you’re getting the most efficient solution without overspending.

Small Generators (5,000–7,500 watts)

These generators can power essential appliances and a few small devices but won’t run your entire home.

Mid-Sized Generators (8,000–12,000 watts)

These generators are ideal for homes that want to run several appliances and lights simultaneously. They can power most of the essentials with some room for flexibility.

Whole-House Generators (12,000–22,000 watts or more)

These units can handle everything in your home—HVAC, kitchen appliances, lights, electronics, and more. They are ideal for homeowners who want complete peace of mind during extended outages.

Roth Home’s technicians work with you to evaluate your needs and provide free, transparent estimates, so you know exactly what to expect—no hidden fees, no surprises. We take the guesswork out of choosing the right generator.

Step 4: Professional Installation

Proper installation is crucial for your generator’s performance and longevity. While it may be tempting to try and install a generator yourself, it’s always best to leave it to the professionals. Installation involves working with natural gas or propane lines, electrical circuits, and local permits. You need a certified technician to ensure everything is done safely and in compliance with regulations.

At Roth Home, we only send certified, drug-tested technicians to handle your generator installation. We adhere to the highest safety standards and offer reliable, professional installation that you can count on. After installation, we test the system and provide detailed instructions on how to use it.

Step 5: Keep Your Generator Maintained

Generators need regular maintenance to ensure they work when you need them most. Neglecting maintenance can lead to unexpected failures during a power outage. At Roth Home, we offer comprehensive generator maintenance services to keep your unit running smoothly.

Maintenance Checklist:

  • Change oil and replace filters
  • Test the battery and connections
  • Inspect fuel systems for leaks or clogs
  • Test the system with a load to ensure proper functionality

With our No Breakdown Guarantee, you can rest assured that your generator will perform when needed. If anything goes wrong, we’ll make it right at no extra charge.

The Advantages of Owning a Generator

Having a generator is more than just a convenience—it’s a safeguard for your home and family. Here’s what owning a generator can protect you from:

  • Power outages: Keeps essential systems running during blackouts
  • Comfort: Ensures your heating or cooling system stays operational
  • Food and medication: Prevents food spoilage and keeps medical equipment running
  • Security: Maintains lighting and security systems

Choosing a generator means choosing reliability and peace of mind, knowing that one call does it all when it comes to your home’s power needs.
