Maintenance and Upkeep for A Home Standby Generator

Home Improvement

Residences that are located in regions that see a lot of heavy wind and bad weather are more prone to having their power knocked out. We all know how much fun that can be, you’re left fumbling around in the dark, the food in the fridge and freezer starts to spoil, the indoor temperature of the home can be very hot or very cold depending on the time of year, and you can feel cut off from the outside world because your TV, smart devices, and your phone are out of commission.

Now who really wants to live like that? Why should your comfort and safety be at the whim of the power company? If a wire goes down or a transformer explodes, you’re at the mercy of the technicians working to fix the issue. For all you know that could be hours or days, depending on the cause of the problem. If this sounds like something you and your family have been forced to endure even once, it may be time to hook up a generator so you have a reliable backup power supply at your disposal when the lights go out again.

Whether you plan on getting a portable backup generator or a generator transfer switch, you want to be sure you take good care of your equipment so it’s always at the ready. That means scheduling routine maintenance to ensure that your unit is working at peak performance at all times.

Think of it like your car, you perform regular maintenance on that machinery, so you stay on the road. Well, it’s the same with your standby generator and most of the upkeep is pretty similar to your car’s engine. You’re dealing with many of the same components, oil, fuel, filter, and so on. So with that in mind, let’s check out what kind of maintenance and upkeep you need to perform to guarantee that your generator will start up the next time the power is interrupted in your home and you and your family are left in the dark.

Read Your Owner’s Manual First

This is the heart of any maintenance and upkeep schedule. You must read through your generator’s owner’s manual thoroughly before you do anything with the unit. Everything you need to know about operating and maintaining your generator is going to be included in that document, from the types of maintenance you need to implement to how you should operate the unit in order to preserve its lifespan.


One of the many essential components that is necessary for a gas-powered generator to operate properly. Many generators run on different grades of fuel, but where good maintenance is concerned, you will need to perform more upkeep on those generators that run on diesel. That way you can rest assured that the generator will start whenever you need it and that maintenance will help you prevent the fuel lines from clogging and blocking the flow of gas into the engine.


Using your automobile as an example once more, you wouldn’t forget to check the levels or even change the oil in your vehicle. Don’t do it with your generator. The oil serves much the same purpose, but you don’t need to change it as often, about every two years or after two hundred hours of operation should be sufficient. Fortunately, changing the oil in your generator is a lot easier than your motor vehicle. You just drain the old oil and replace it with the brand-new stuff.

Air Filter

Every generator may not run on the same type of gas, but they all require proper air flow to get through the system. Clean air is important for a generator to run smoothly and it’s up to your air filter to ensure the system gets proper clean air flow. When the filter is dirty, the generator will have issues with operation, so change the air filter periodically to make sure you’re not suffocating the generator.

Fresh Spark Plugs

Your generator does use spark plugs and, like your air filter, will need to be replaced every so often so they are allowing your generator to work properly. An annual check of the spark plugs is all that you need to do and those that are showing significant signs of wear and tear should be tossed out and replaced with a fresh set. The spark plugs can often get overlooked but don’t neglect these vital components of your generator, otherwise you could be left in the dark.
