How Long Do Standby Home Generators Last?

A standby home generator is an excellent investment to keep your home powered up during unexpected power outages. It can provide you with an uninterrupted power supply to keep your food from spoiling, your heating and cooling systems running, and all your electrical appliances functioning normally.



However, as a homeowner, it’s essential to consider how long your standby home generator will continue to serve you before you need to replace it. Generally speaking, a decent generator can last for 20 to 40 years. That’s a pretty wide timeframe, though. To get a more accurate estimation of how long your generator will last, you have to consider factors like your maintenance routine, how often you use your generator, and more. Read on to delve deeper into how long standby home generators can last and what factors may affect their longevity.


Maintenance Schedule

Regular maintenance is key to making your standby home generator last longer. Maintenance involves routine inspections and cleaning, as well as basic tasks like checking filters and fluid levels.


You should base your maintenance schedule on the manufacturer’s instructions as well as how often you use your generator. If you run your generator every couple of weeks, it will need more maintenance. However, if you don’t use it as often, it’s still a good idea to turn the generator on once in a while and let it run for a few minutes to ensure everything still works smoothly.


Usage

As with most appliances, how frequently you use your generator will affect its lifespan. The number of hours your generator runs annually can impact its longevity. For instance, overusing your generator can lead to overheating and other issues. If you have to use your generator more often than usual, remember to keep an eye out for problems and adjust your maintenance schedule to keep it in good condition.


Equipment and Service Quality

Quality and brand are also factors that influence how long your home standby generator will last. High-end generators have better materials, parts, and design, resulting in longer lifespans. The installation process also plays a huge role in the quality and dependability of your generator, so make sure you hire a professional to ensure everything is set up correctly.
