A Guide to Choosing A Whole-Home Generator

A Guide to Choosing A Whole-Home Generator

When it comes to ensuring the comfort, safety, and functionality of your home during power outages, a whole-home generator can be imperative. These robust devices are designed to keep your lights on, appliances running, and essential systems operational when the grid fails. However, selecting the best whole-home generator for your needs is no simple task. We hope this article provides you with knowledge on how to choose the best whole-home generator, considering factors like power capacity, fuel source, and advanced features.

Determine Your Specific Needs

  • Power Requirements –

    The first step in choosing a whole-home generator is to determine your power needs. Calculate the wattage required to power the essential appliances and systems in your home during an outage. Make a list of crucial items (i.e., refrigerators, heating and cooling systems, sump pumps, medical equipment, and lighting). Add up their power requirements in watts. It’s essential to ensure the generator you choose can handle this total wattage.

  • Generator Size –

    Generator size is a crucial factor in ensuring your power needs are met during an outage. The generator’s size is typically measured in kilowatts (kW). Choose a generator that can provide at least the minimum required wattage, but it’s advisable to opt for a slightly larger model to accommodate unexpected power surges or additional appliances in the future.

  • Noise Level –  

    The noise level of a generator is an important consideration, especially if your generator will be located near living spaces. Inverter generators tend to be quieter than conventional generators, making them an excellent choice for residential areas.

Choose the Right Fuel Source

Whole-home generators typically come in three primary fuel source options: natural gas, propane, and diesel. Each has its advantages and disadvantages:

  • Natural Gas:

    Natural gas generators are a popular choice because they are connected directly to your home’s gas line, providing a continuous supply of fuel. They are clean-burning and require less maintenance. However, they might not be available in all areas.

  • Propane:

    Propane generators offer versatility and reliability. They are available in various sizes and can be used in areas without natural gas connections. Propane is easy to store and has a long shelf life.

  • Diesel:

    Diesel generators are known for their durability and fuel efficiency. They can provide a reliable power source during extended outages. However, diesel generators can be noisier and require more maintenance.

Installation & Maintenance

  • Quality Installation:

    Installing a whole-home generator is not a DIY project. Seek the assistance of a professional electrician or generator installer who can assess your home’s electrical system and ensure proper installation. They can also guide you through obtaining necessary permits and meeting local regulations.

  • Maintain Your Investment:

    Generators are long-term investments, and it’s essential to consider warranty and maintenance requirements. A reliable manufacturer will typically offer a considerable warranty. Additionally, inquire about the maintenance needs of your chosen generator, as regular servicing is critical to its longevity and reliability.


In conclusion, choosing the best whole-home generator for your needs is a significant decision. To make an informed choice, consider your power requirements, fuel source, generator size, noise level, fuel efficiency, warranty, and advanced features. With careful consideration and the assistance of a professional, you can select a whole-home generator that ensures your peace of mind and keeps your home running smoothly in the face of unforeseen power outages.
