Buying Guide

When choosing the best whole house generator, various features must be considered. By evaluating these essential factors, you will be able to select the ideal generator for your needs. In this buying guide, we will outline key elements to consider before making a purchase.

Size and Capacity

The first factor to consider is the generator’s size and capacity. You need to select a generator with enough power output to support your home’s electrical needs. To determine the suitable size for your home, calculate the total wattage of the appliances and devices that will be powered by the generator during an outage. As a rule of thumb, opt for a generator with slightly more capacity than your calculated total wattage, as this will provide room for growth or unexpected power demands.

Fuel Type

Generators run on different fuel types, including gas, propane, diesel, and natural gas. Each fuel type has its own advantages and disadvantages:

Fuel Type	Advantages	Disadvantages
Gas	Widely available	Short shelf life, less efficient
Propane	Long shelf life, clean-burning	Less energy dense
Diesel	Efficient, long-lasting	Noisy, high maintenance
Natural Gas	Readily available, clean-burning	Limited availability in some areas, less portable

It’s important to consider the availability and cost of the fuel type in your area, as well as your personal preferences and priorities, when choosing a whole house generator.

Transfer Switch

A transfer switch is a vital component as it connects the generator to your home’s electrical system. There are two main types of transfer switches: manual and automatic. A manual transfer switch requires you to manually switch the power source between the generator and the main power grid. In contrast, an automatic transfer switch detects a power outage and automatically switches the power source, ensuring minimal disruption. While automatic transfer switches are more convenient, they come with a higher price tag.

Noise Levels

Generators can be noisy, and their noise levels vary depending on the model and fuel type. Consider the noise levels of the generator, especially if you live in a densely populated area or have close neighbors. Some generators come with noise-reduction features, such as insulated enclosures or dampening materials.

Warranty and Customer Support

A good warranty and reliable customer support are crucial when investing in a whole house generator. Check the warranty terms and ensure they cover a reasonable time frame and provide comprehensive protection. Also, research the manufacturer’s customer support reputation to ensure assistance will be available if needed.

By thoroughly evaluating these key factors, we are confident that you will be able to find a whole house generator that meets your needs and provides reliable power during outages.
