How to Determine the Age of a Generac Generator

How to Find the Age of a Generac Standby Generator

Did you recently buy a house with a standby generator? Perhaps you installed your unit years ago—you simply can’t remember how many. Finding the age of your Generac standby generator is important for maintenance, troubleshooting, and replacement timelines. If you’re wondering how old your Generac generator is or looking for a Generac generator serial number guide, you’re in the right place.

Identifying Generac Generator Age

Some manufacturers include the date of manufacture within the serial number. Generac does not. Instead, they use a sequential numbering system that doesn’t provide any direct clues to consumers about when the generator was made.

So, how do you determine the age of a Generac generator? The only way is to locate the serial number and contact the company directly.

Where to Find the Serial Number

The Generac generator model information and serial number aren’t always in an obvious place. Here’s where to look, depending on the type of generator you own:

• 7.5kW PowerPact: To access the data tag, remove the top four screws and lift the front panel. You’ll find the tag on the black panel to the left. A 6 mm Allen wrench is required to remove the bolts securing the lid.
• Residential air-cooled standby generators: The serial number is on a decal on the dividing panel to the left of the control panel. You’ll need to unlock and lift the lid to access it.
• Commercial liquid-cooled standby generators: The serial number is inside the enclosure, on the right-hand side of the control panel. You’ll need to unlock and remove the side panel to access it.

If you’re having trouble finding your Generac generator’s serial number, check Generac’s official support page for more guidance.

Contacting Generac for the Manufacturing Date

Once you have the serial number, call Generac Customer Support at 888-436-3722. A representative can look up the Generac generator manufacturing date in their internal database.

If your generator was registered at the time of purchase, the representative may also be able to look up the Generac generator documentation by property address. However, the company only keeps records for 12 to 15 years. If your generator is older than that, they won’t be able to verify its age. This tells you it’s getting old and probably due for a replacement soon.

How Long Does a Generac Generator Last?

Several factors affect a Generac generator’s lifespan, including:

• Usage: Generac standby generators are designed for about 3,000 hours of operation. If the unit runs a weekly self-test and experiences occasional power outages, this would translate to a lifespan of 25 to 30 years.
• Age: The International Association of Certified Home Inspectors (InterNACHI) gives residential standby generators a lifespan of 12 years. Based on our inspection experience, we agree. So, it’s more correct to say the average lifespan of a Generac generator is 3,000 hours or 12 years, whichever comes first.
• Maintenance: Generators that receive regular oil changes, filter replacements, and professional servicing last longer than neglected units.
• Environmental conditions: Generators exposed to excessive moisture, debris, or extreme temperatures may experience premature aging.

Signs Your Generac Generator Needs to Be Replaced

Most people wonder how to check a Generac generator’s age because they’re worried it’s getting old. Consider these signs that indicate it’s time for an upgrade:

• Frequent repairs: If your generator breaks down constantly, replacing it may be better than paying for continued repairs.
• Trouble starting: A generator that struggles to start may have issues with its battery, fuel system, or other components. If you’ve performed basic maintenance and the problem persists, age could be the culprit.
• Rising fuel consumption: Does your generator seem to be using more fuel than usual? This indicates the engine is wearing out. Older generators often become less fuel-efficient near the end of their lifespan.
• Excessive noise or vibration: A well-maintained generator should run smoothly. If you notice strange noises, excessive shaking, or vibrations, internal components may be failing.
• Outdated technology: Newer Generac models have advanced monitoring, better fuel efficiency, and quieter operation. An upgrade might be worth it if your generator lacks these features.
• Corrosion or physical damage: Rust, cracks, or other structural damage may indicate your generator is no longer safe or reliable.

In short, if your generator is over 12 years old or showing signs of performance decline, it’s time to consider a replacement.
