When the power goes out, a generator quickly becomes one of the most valuable appliances in your home. It keeps your lights on, your food cold, and your air conditioning running when you need it most. But just like any other machine, a generator requires regular generator maintenance. That raises the big question: can you service your generator yourself, or should you always call in a professional?
The answer depends on the type of maintenance, your comfort level with mechanical work, and—most importantly—safety. Let’s explore the essentials of generator maintenance, what you can do on your own, and when it’s best to leave it to the experts.
What Is Generator Maintenance?
Generator maintenance is the process of checking, cleaning, and repairing your unit to ensure it’s ready to perform when an outage strikes. Without regular upkeep, a generator can develop problems like clogged filters, battery failure, or fuel system issues. In fact, the most common problem with generators is that they fail to start—often due to a lack of proper care.
Can You Service Your Generator Yourself?
The short answer: yes, but only partially.
There are several routine tasks you can safely handle at home, such as:
- Checking and changing the oil – Just like a car, generators need fresh oil for smooth operation.
- Replacing air filters – Clean filters keep dust and debris out of the engine.
- Inspecting spark plugs – A quick check can prevent misfires.
- Running the generator periodically – Monthly test runs keep the engine lubricated and ready.
However, more complex tasks—like adjusting the voltage regulator, inspecting the transfer switch, or diagnosing electrical faults—should be handled by a trained technician.
Safety First: What to Keep in Mind
Working on a generator involves flammable fuel, moving parts, and sometimes high-voltage electricity. If you’re not confident in your skills, it’s always safer to call a professional. Remember: the cost of a service call is far less than the potential damage caused by a mistake.
The Benefits of Professional Generator Maintenance
Even if you handle small tasks on your own, scheduling regular professional inspections is key. Certified technicians will:
- Test the electrical output.
- Inspect the fuel system for leaks or clogs.
- Check and replace worn components.
- Ensure your system complies with local codes.
These thorough checks not only extend the life of your unit but also give you peace of mind that your generator will be ready when you need it most.
How Much Should It Cost to Service a Generator?
On average, generator maintenance can cost between $150 and $300 per year for basic servicing. Prices may vary depending on the generator’s size, age, and condition. While this may seem like an added expense, it’s a small investment compared to the cost of repairs—or worse, being without power when you need it.
DIY vs. Professional: Finding the Right Balance
The best approach is a combination of both. Handle the small, safe tasks yourself to keep your generator running smoothly between professional visits.
Then, schedule at least one professional service per year (or more if you use your generator frequently). This balance saves you money while ensuring reliability.
So, can you service your generator yourself? Yes—but only to a point. Taking care of simple tasks like oil changes and test runs is a great way to extend the life of your unit. But when it comes to complex inspections and safety-critical checks, trust a professional. After all, your generator’s job is to protect your home during outages. A little extra attention today could make all the difference tomorrow.
