Top Signs Your Generator Needs Summer Maintenance

June 13, 2025

Summer is here, Tomball — and with rising temperatures and increased storm activity in the Gulf, your generator is about to become one of the most important pieces of equipment you own, besides the Keurig! Whether it’s keeping your home cool during a heatwave or powering essential appliances during a blackout, your generator should be ready to perform at a moment’s notice. But is it?

If your generator is showing any of the signs below, it’s time for summer maintenance — before you’re left in the dark.

1. Unusual Sounds During Operation

A well-maintained generator should hum along with minimal noise. If you start to hear clanking, grinding, or popping sounds, it’s a red flag. These noises can indicate anything from loose parts and worn bearings to internal damage. Ignoring these sounds could lead to costly repairs — or a total breakdown right when you need power most.

2. Difficulty Starting Up

Your generator should start easily — especially when tested regularly. If you’re experiencing slow cranking, multiple attempts to start, or complete failure to power on, there may be an issue with the battery, fuel system, or spark plugs. Houston heat can exacerbate battery problems, so don’t wait to get this checked out.

3. Visible Leaks or Corrosion

Keep an eye out for oil, fuel, or coolant leaks, as well as signs of rust or corrosion. These are not just cosmetic issues — they can signal deeper problems like cracked hoses or failing seals. Leaks can also create fire hazards, especially in dry summer conditions.

4. Overdue for Routine Service

When was the last time your generator had a professional checkup? If it’s been over 12 months (or more frequently for heavy use), you’re overdue. Even if your generator seems to be running fine, internal wear and tear or dirty filters could be silently reducing its efficiency.

5. Warning Lights or Alerts

Modern generators often come with diagnostic systems. If your unit is flashing warning lights or showing maintenance alerts, don’t ignore them. These alerts are designed to prevent bigger failures down the line — but only if you act on thema promptly.

Common generator error codes include: 1100, 1201, 1600, 1300, 1800, and more.

Why Summer Maintenance Matters

Extreme heat, increased power demands, and unpredictable weather can all stress your generator. Preventive maintenance ensures your system runs efficiently, reliably, and safely — saving you money and headaches when it matters most.

Don’t wait until the power goes out to realize your generator isn’t up to the task. If you notice unusual sounds, startup issues, or know it’s time for a tune-up, schedule your summer maintenance today. It’s a small step that can make a big difference when the next storm hits.
