Like most things, whole-house standby generators need regular maintenance to ensure they can perform at peak. Usually, you should have maintenance done on your generator every 2 years (or after 200 hours of use, whichever comes first). Maintenance on a standby generator means checking and changing its oil (yes, like a car), checking the spark plugs, and replacing the air filter. Also like a car, your stay generator will come with an owner’s manual with details about the specific needs of your particular model. If issues with your generator arise it could be a number of issues. In some cases it could be an issue with insufficient fuel or an issue in fuel intake. Other times, an issue known as “wet-stacking” can occur. “Wet-stacking” refers to the build-up of unburned fuel in the generator’s exhaust system. Both of these issues have the potential to lead to total system failure, which is why it’s so important to perform routine maintenance and hire professional help when an issue does arise.
