When you have a whole-home generator, generator maintenance is so important! In an age where power outages can catch us off guard and disrupt our lives, having a dependable standby generator is crucial to keep your home running smoothly when the unexpected happens. 

Your MK Electric pros know how vital it is to have a trustworthy backup power source. Proper maintenance of your standby generator is key to ensuring optimal performance and a prolonged lifespan. Today, we’re offering five must-do maintenance tips to make sure your generator is always ready to spring into action when you need it. We’ll also explore the benefits of having a whole-home generator for your household. 

1. Consistently check and change the Oil for Generator maintenance

Similar to your vehicle, your standby generator requires regular oil changes for optimal operation. Oil can accumulate debris over time, diminishing its effectiveness. To keep everything running smoothly, monitor the oil levels frequently and change them according to the manufacturer’s guidelines. Generally, oil should be changed every 100 to 200 hours of operation, depending on your generator model. Routine oil checks and changes can prevent engine wear, ensuring your generator seamlessly starts during a power outage. 

2. Maintain Clean Air Filters for Generator maintenance

Air filters are crucial for keeping your generator’s engine free from harmful dust and debris. Dirty or clogged air filters can hamper engine efficiency and potentially cause long-term damage. Inspect your generator’s air filters every few months and replace them if they appear to be blocked or dirty. Clean air filters are essential for efficient generator operation and help avoid expensive repairs. 

3. Regular Battery Inspections for Generator maintenance

The battery is critical for your standby generator’s functionality during an outage. Regularly examine the battery’s charge and look for any signs of corrosion or damage. Clean the battery terminals if needed, and consider replacing the battery if it’s approaching the end of its service life. A well-maintained battery guarantees that your generator is primed to start without delay in times of need. 

4. Conduct Regular Generator Tests for Generator Maintenance

To ensure your generator is ready for unexpected outages, test it at regular intervals. By running your generator for 15 to 30 minutes each month, you can spot potential issues early on. This practice also helps keep the engine lubricated, ensuring it starts up smoothly when required. Listen for any unusual sounds or vibrations during testing, as these could signal maintenance needs. 

5. Annual Professional Maintenance Checks for Generator maintenance

While performing regular DIY maintenance is beneficial, scheduling an annual professional inspection is equally important. A certified technician provides a comprehensive examination and can detect issues you might overlook. They will inspect key components like the fuel system, electrical connections, and control systems for any wear or faults. Professional maintenance gives you confidence that your generator is in top condition and ready to deliver backup power anytime. 

Why a Whole-home Generator is a Smart Choice 

Power outages can lead to major disruptions and potential damage to your home. A whole-home generator offers several advantages that make it a wise investment. 

  • An uninterrupted power supply for your entire home during an outage keeps everything functional—lights, appliances, HVAC systems, and security features—ensuring comfort and safety. 
  • Avoid damage to electronic devices by providing smooth power transitions and preventing sudden shutdowns. 
  • Enhance your property’s market appeal and value with the addition of a whole-home generator.
