The clearest signs a swamp cooler needs repair are weak airflow, warm air at the vents, musty smells, water leaks at the base, loud rattling, or pads that no longer stay wet. Any one of these usually points to a worn pump, dry pads, a clogged water line, or a failing motor.
Watch for these symptoms
- Air feels warm or humid rather than cool
- Pads appear dry, crusty, or stained with mineral buildup
- Water dripping from the housing or rooftop unit
- Loud squealing or rattling when the blower runs
- Musty, swampy odor inside the home
Most issues are inexpensive when caught early — replacing pads, the pump, or a float valve before the motor or housing is damaged. Our team handles full swamp cooler repair and maintenance, and we can also recommend a switch to central AC or ductless cooling if your unit has reached the end of its life.
