COMMON GENERATOR PROBLEMS

Standby Power Symptoms & What They Mean

These are the issues we see most in Upstate SC—what they usually point to, and how we fix them.

Won't Start / Overcrank

Often weak battery, failed starter, low LP/NG pressure, or ignition issues. We test the start circuit, fuel supply, and controls, then correct the root cause.

Starts, Then Shuts Down

Fuel delivery, overheating, oil/low-pressure switches, or controller faults. We verify airflow, oil level/pressure, and regulator performance.

No Power to the House

Transfer switch, breaker, wiring, or controller issues. We test ATS operation, tighten lugs, and restore safe transfer.

Low/High Voltage or Frequency

AVR/governor problems, dirty throttle body, or sensor faults. We calibrate and replace components as needed and verify under load.

Battery/Charging Problems

Aged battery or failed charger. We load-test, replace if needed, and confirm the charger is maintaining voltage correctly.

Gas Leaks / Fuel Pressure Issues

Call immediately. We're GasTite® certified to check fittings/regulator and ensure proper LP/NG delivery and leak-free operation.

Real Reviews from Homeowners Across Upstate SC

We're proud to serve homeowners across Greenwood, Anderson, Abbeville, Laurens, and McCormick Counties. Here's what real customers had to say about their experience with 5 Lakes Heating & Air.

Extremely prompt and very helpful on the phone to troubleshoot before coming out. Ready available parts and he was very thorough in cleaning and checking to make sure everything else was in order with my generator. I highly recommend using Justin.

Generator Diagnostic & Repair

So grateful for Justin. We had an issue with our standby generator and as a result, had no backup power during an outage. I contacted Justin and he was very prompt to come out the evening of the same day that I called him. We have a newborn and knowing that, he made sure to get us taken care of ASAP. I had contacted another company the day before, but Justin beat their price significantly for the repair. Thank you! Will gladly use 5 Lakes again!
