With frequent storms, power outages, and the occasional hurricane, ensuring that your generator is in top working condition is key to keeping your home safe and comfortable. But how do you know when your generator needs attention? Here in Houston, having a backup generator is more than just a luxury—it's a necessity.

At Abacus Plumbing, Air Conditioning, and Electrical, we specialize in backup generator service, and we’ve seen all the telltale signs of a backup generator in need of professional care. To help you stay ahead of any issues, we’ve compiled this list of the top 5 signs your generator needs maintenance. Spotting these early on could save you from an unexpected failure during the next power outage.

1) Difficulty Starting or Delayed Start

If your generator is slow to start or struggles to power up, this is one of the clearest signs it needs maintenance. Standby generators are built to kick on automatically during a power outage, so if there’s a delay or trouble starting, it’s a sign something might be wrong. The problem could be related to:

Battery issues: A weak or failing battery is often the culprit behind startup problems. Over time, batteries lose their charge and may need to be replaced.
Fuel delivery problems: A blocked or clogged fuel line can prevent the generator from getting the fuel it needs to operate smoothly.
Spark plugs: Dirty or worn-out spark plugs can cause ignition problems.

If your backup generator isn’t starting up as quickly as it should, it’s time to call for a generator maintenance service. Our professional technicians can diagnose the issue and ensure your generator is ready when you need it most.

2) Frequent Alerts or Error Messages

Many modern backup generators, especially Generac models, come equipped with monitoring systems that send alerts if something’s wrong. These alerts often point to:

Low oil levels: Without enough oil, the generator can overheat and sustain damage.
Overheating: Blocked vents or cooling system failures can cause your generator to overheat, leading to more significant problems.
Fuel line leaks: Leaking fuel lines is not only dangerous but can also prevent your generator from functioning properly.

If your backup generator is displaying alerts or error messages, it’s a good idea to schedule a generator maintenance check. Ignoring these alerts could lead to a complete failure during the next power outage.

3) Unusual Noises or Smells

Is your generator making strange noises or giving off unusual odors? Generators are built to run smoothly, so if you start hearing sounds like knocking, sputtering, or grinding, that’s a clear sign that your unit needs attention. Possible causes include:

Knocking or banging: This could indicate loose parts or internal engine issues.
Sputtering: If your generator is sputtering, it might not be receiving enough fuel or the fuel system could be clogged.

Likewise, if you notice any strange odors—like burning or the smell of fuel—it’s time to call for backup generator service. If left untreated, these issues can lead to bigger, more costly repairs.

4) Visible Wear and Tear

Over time, exposure to the elements can cause wear and tear on your generator. This might include:

Rust or corrosion: Rust can damage the exterior and affect the performance of your generator, especially in humid environments like Houston.
Damaged wires: Frayed or exposed wires are a serious safety hazard that can lead to electrical malfunctions or even fire.
Leaks: Pooling fluids, whether it’s oil, fuel, or coolant, are a sign that your generator needs immediate attention.

Routine generator maintenance services can catch these issues early, ensuring that minor wear and tear doesn’t turn into a major repair job.

5) Performance Issues During Tests

Regular testing is essential to make sure your backup generator is functioning as it should. If you notice any performance issues during routine tests, such as:

Fluctuating power output: If the generator isn’t providing consistent power, there could be an issue with its voltage regulation.
Power surges: Surges can damage appliances and electronics connected to the generator.
Short runtime: If your generator shuts down after only running for a short period, there could be a fuel supply or cooling issue.

If your backup generator isn’t passing these tests, it’s time to schedule a generator service. Routine testing can help prevent a surprise failure during an actual power outage.
