Losing power can turn an annoyance into something devastating. This isn’t just about the lights shutting off. An outage can impact your food, your work, and your overall welfare. That is why generators are such lifesavers during these events. However, a standard generator can take a lot to upkeep, and it isn’t meant for long-term or serious situations. That’s why it pays to invest in whole house generators. They’re costly, but they are more than worth it when things remain the same around your home during a storm or other severe weather situations.

But what makes for a quality whole house generator? Well, we’ll help you see what to focus on so that you find the best whole-house backup generator that suits your needs the most.

Type of Generator

When you’re looking at whole house generators, you are generally checking out two types: standby and portable.

A standby generator is something that is installed permanently to your residence, thus requiring an expert like an electrician to set it up. These are used a lot by individuals that live in areas prone to storms as they are ideal at triggering seconds after an outage occurs. This ensures that you hardly notice the outage at all.

As for a portable generator, it is as its name implies. These are smaller and capable of being transported around. Some are still sized well enough so that they roll away on tires, while others are compact enough to be picked up and carted off instead.

So, which one is best? Well, it boils down to what you need. If you want something more permanent, then the standby solution is ideal. If you need something to take with you to someone else’s home, then check out your portable whole house options.

Power Requirements

Just how much power do you need? Are you looking to power up everything in your home from the TVs, to the fridge, and even the AC or the heat depending on the temperature? Or maybe you only want to power up the essentials?

Not only does what you need to power matters, but the size of your home plays a major role too. Smaller homes, of course, won’t take up as much as larger ones. Thankfully, there are whole house generators that can address all of your concerns.

Fuel Source

Generators can be fueled by different sources like gasoline, solar, battery, and propane. Natural gas is a common choice due to how readily available it is. However, propane tends to have its advantages as it can generally last longer, giving you more time with the generator running before you ever have to go out and refill it.

For whole house generators, the less time you spend on it via maintenance and everything else, the better. You can always luck out and find yourself a quality dual fuel generator. This means you can power it up with multiple sources, giving you much-needed versatility so that you can change up your fuel source as needed.

Ease of Use

Although whole house generators tend to require professional installation, controlling and managing them should be relatively easy. Many of these generators today feature Wi-Fi capabilities, allowing you to sync up with an app or a smart home device like Alexa to control the unit. This makes things far more intuitive and easy, and quickness is needed when it comes to outages.

Also, consider how simple it is to turn the unit on and off. Some feature a single push-button, while others have a pull cord system. An electronic start tends to be faster and more instantaneous, but this isn’t always guaranteed. One thing to be wary of is the location of the generator, especially for the more portable options as they can generate a lot of pollutants so need to be away from any locations where people are sleeping or spending time.

When choosing what we think are the best whole house generators for 2022, we connected with our community of Metallurgists to find out what the generators that have been working for them as well as run data analysis on customer feedback on the most popular generators in use.

Here are the 8 whole house generators we recommend for 2022:
