generator Orange County, NY Whole-house generators are a valuable asset for any homeowner, providing a reliable power source during outages. However, to ensure their longevity and optimal performance, regular maintenance is essential. Here are some tips to keep the whole-house generator in your Orange County, NY home in top condition.

Regular Inspection

Inspect your generator regularly for any signs of wear and tear, such as frayed wires or corroded parts. If you notice anything unusual, consult a professional for repair or replacement.

Oil and Filter Change

Just like any engine, your generator needs regular oil and filter changes. Refer to your generator’s manual for the recommended oil and filter change interval. Typically, it’s after 100 hours of use or at least once a year.

Fuel Check

Always ensure your generator has enough fuel. Running a generator on low fuel can damage the engine. Also, check for any leaks or damages to the fuel tank regularly. It’s a good idea to always have enough propane available to run your generator for one week. Whenever you need more propane, contact Downey Energy to schedule your next propane delivery or sign up for automatic delivery.

Battery Maintenance

The battery is a crucial component of your generator. Keep the battery clean and free from corrosion. Regularly check the battery’s electrolyte level and top it up with distilled water if necessary.

Air Filter Replacement

A clogged air filter can reduce your generator’s efficiency. Replace the air filter regularly to ensure optimal performance. The frequency of replacement depends on how often you use your generator.

Exercise Your Generator

Generators need to be run regularly to keep them in good working condition. Run your generator for a few minutes every month, even if you don’t need the power. This helps to keep the engine parts lubricated and prevents carbon build-up.

Professional Servicing

While you can do most of the maintenance yourself, it’s advisable to have your generator serviced by a professional at least once a year. They can perform a thorough inspection and address any potential issues. At Downey Energy, we sell, install, maintain, and repair Generac whole-house generators.

Safe Storage

When not in use, store your generator in a clean, dry place. Cover it to protect it from dust and moisture.


Regular maintenance is key to ensuring your whole-house generator is ready when you need it. By following the tips listed above, you can prolong the life of your generator and ensure it provides reliable power during emergencies. Remember, a well-maintained generator is a dependable one.
