Rain or shine, the backup source of power to your home needs to be reliable.

The average generator can last a solid 20 years or so. If your generator shows signs of decreased performance or changes in fuel consumption, it’s time to get it evaluated by a professional. Now’s the time to learn when and why to upgrade.

When Should You Upgrade Your Generator?

If your generator is older and showing the following signs, you might need to consider a replacement. 

Increasing Repair Expenses

As backup generators begin to age, their repair costs tend to increase because they will malfunction more often. What complicates things further is that older generator parts are harder to find. If a part is rare, you’ll likely have to pay quite a bit for the repair. 

Inconsistent Performance

If your generator begins to provide power intermittently, or you notice it taking a bit longer to turn on, you could have a failing battery. Also, in older generators, there might be dirt or debris clogging up the radiator. Both may cause a generator to perform poorly.   

Insufficient Power

When you buy a generator for your home, consider how much power you’ll need if the power goes out. If your generator doesn’t offer sufficient capacity, consider upgrading to one that suits your needs. 

Wear and Tear

As your generator ages, you’ll start to see more signs of wear and tear, especially if it’s more than ten years old. These signs can include dirty parts, damage from the elements, and leaks. As these issues pile up, you’ll start to see significant decreases in performance. 

Using Excess Fuel

A generator’s fuel efficiency will also start to slip with age. A decrease in fuel efficiency will lead to reductions in performance. 

Why Should You Upgrade Your Generator?

There are several reasons you should consider upgrading your current generator.

For Better, More Reliable Technology

A benefit to upgrading your generator to a new version is that most newer generators have automatic transfer switches. They turn your unit on as soon as the power goes out. Some also have the option to monitor your generator through your mobile device.

For Greater Power Needs

Modern generators have better power management capabilities. They are more efficient and require less maintenance. Newer generators also come with a full range of power options, so you shouldn’t have any trouble finding one that suits your home. 

For More Energy-Efficiency

Nowadays, there are far more options for energy-efficient generators than in previous years. There are even some that run on two or more fuel types. Generators that use multiple fuels provide longer-lasting power. 

Considerations When Buying a New Generator

Here are a few things to take into consideration when purchasing your next generator.


If you just need something to power your home, a lower-capacity unit should do just fine. Businesses will need high-capacity, industrial-grade generators. 


Generators typically put out a lot of exhaust. Always install your unit outside to provide proper ventilation. Always place the generator safely away from doors, windows, and vents to prevent exhaust from getting inside.  

Fuel Type

The two main types of fuel for generators are diesel and natural gas. 

Diesel generators are often safer to store than natural gas because they are less flammable, and they will often cost less than natural gas units. They’re ideal if you need a commercial generator.

A natural gas generator can be connected directly to your gas line. You won’t have to worry about manually refueling. Also, natural gas is nearly odorless, which is nice if the generator is close to your house. 


Although it’s tempting to DIY your installation, generator installation can be hazardous. Therefore, it’s best to call a professional to install your generator just to make sure it’s done safely and correctly.
