Top Signs Your Chiller System Needs Repair

If your chiller isn’t right, the first clues show up in data and comfort long before the system fails. Smart facilities in Seattle watch trend logs, energy bills, supply/return temps, and alarm histories to spot trouble early. Here’s how to recognize the signs and schedule service at the right time.

Early warning signs of chiller trouble

  • Rising energy consumption: kWh per ton climbing week over week points to fouled tubes, poor condenser airflow, or incorrect charge.
  • Poor cooling capacity: Supply water temperature misses setpoint or takes too long to pull down on startup.
  • Frequent short-cycling: Controls or load issues cause compressor starts to spike, accelerating wear.
  • Unusual noises or vibration: Bearings, cavitation, or refrigerant flow issues.
  • Alarms and trips: High head pressure, low suction, oil level, or flow switches should never be ignored.

Common root causes in Seattle buildings

  • Dirty condenser coils or clogged cooling towers from pollen and urban dust
  • Water-side scaling due to untreated or poorly treated loops
  • Economizer or VFD control problems after winter shoulder seasons
  • Refrigerant leaks, non-condensables, or sensor drift

What your tech should check

  • Tubing cleanliness, approach temps, superheat/subcool readings
  • Condenser airflow, fan operation, coil condition
  • Flow rates, delta-T, pump performance, strainer condition
  • Controls tuning, safeties, and alarm history

Seattle-specific maintenance tips

  • Schedule coil and tower cleanings before summer heat waves.
  • Verify economizer operation after the rainy season to prevent false readings.
  • Log energy use monthly and flag deviations early.

    Saltwater Church suddenly lost heat in their office building on a Friday. The dispatcher was knowledgeable, professional, and efficient. Caleb came out within about an hour of our call, diagnosed the problem, and got the system up and … More running. He gave us the option of replacing the part that had shorted out, or seeing if the system could work adequately without it. We asked him to locate the part and give us a quote. We got the quote just 2 days later. We are very impressed and will use Five Star again!
