What to Expect During a Generator Maintenance Visit

If you rely on a generator to keep your home powered during outages, regular maintenance is essential to ensure it’s ready when you need it most. Many people wonder what actually happens during a generator maintenance visit. At Thomas Edison Electric, we aim to make this process as thorough and efficient as possible so that you can trust your backup power source. 

Here’s a step-by-step look at what to expect when our certified technicians perform a generator maintenance visit.

1. Initial Inspection and System Check

The first thing our technicians do is perform a visual inspection of your generator system. We look for any visible signs of wear, such as corrosion or loose connections, that could affect performance. This inspection is a crucial step, as it helps catch potential issues before they lead to costly repairs or unexpected failures. After the visual check, we power up the generator to ensure it starts smoothly and assess its overall performance.

2. Electrical Connections

Next, we examine all electrical connections to make sure they are secure and free from damage. This includes checking wiring, plugs, and other connection points that can sometimes become loose due to vibration or general wear and tear. Ensuring secure connections is key to avoiding power disruptions when your generator kicks in.

3. Battery Testing

A generator’s battery is its lifeline for a quick start during an outage, so we pay close attention to it during maintenance. Our technicians check the battery charge and connections, making sure it’s ready to start the generator without delay. If the battery shows signs of aging or weakness, we may recommend a replacement to prevent startup issues down the line.

4. Fuel System Inspection

Generators need a consistent fuel supply to operate effectively, so we inspect the entire fuel system, including the tank, fuel lines, and filter. Our team checks for any leaks, blockages, or signs of contamination in the fuel. Keeping the fuel system clean and functioning well helps ensure smooth operation, especially when your generator has been idle for a while.

5. Oil and Filter Changes

Just like any engine, a generator’s engine needs clean oil to run smoothly. During maintenance, we check the oil level and replace it if necessary, along with any worn-out filters. Fresh oil and filters prevent dirt buildup and keep the engine running efficiently, which extends the life of your generator and minimizes the risk of breakdowns. It’s important to note that more usage requires more attention, especially with lubricant.

6. Coolant Level and Airflow

To prevent overheating, we inspect the coolant levels and ensure there’s adequate airflow around the unit. Proper cooling is essential for safe operation, especially during extended power outages when the generator may need to run for hours or even days. This check helps us confirm that your generator won’t overheat during a critical moment.

7. Diagnostic Test and Final Performance Check

Finally, we run a comprehensive diagnostic test to check for any error codes or irregularities. This test helps us detect minor issues that may not be visible during the inspection. We then perform a final startup test to confirm that the generator is operating correctly and ready for action.

Why Routine Maintenance Matters

Regular generator maintenance is the best way to ensure your generator will work reliably in an emergency. These steps help catch minor issues before they become major problems, extend the lifespan of your generator, and provide peace of mind that your home is protected during outages. At Thomas Edison Electric, our certified technicians follow a thorough maintenance checklist to keep your generator in top shape so it’s ready whenever you need it. Need help? Give us a call today!
