Repairing Portacool Evaporative Cooler/Swamp Coolers
Portacool has made many versions of its evaporative cooler/swamp coolers over the years. Our technicians check the model and serial number, review known issues for that model family and test before replacing parts, so you only pay for what is actually needed.
How we repair your Portacool Evaporative Cooler/Swamp Cooler
An evaporative or swamp cooler pulls dry outdoor air through water-soaked pads so evaporation cools it before a blower pushes it into the house, working best in dry climates. An evaporative cooler/swamp cooler typically includes a compressor, condenser and evaporator coils, fans, a capacitor and contactor, and a thermostat, or a water pump and pads on evaporative coolers. A technician checks airflow, electrical parts and refrigerant pressures, and inspects drains and coils.

Common Portacool Evaporative Cooler/Swamp Cooler problems we fix
What usually causes each symptom, and what our technician checks to confirm it.
Heavy white mineral buildup
- Likely causes
- Hard water concentrating in the pan without enough bleed-off, which crusts pads and the pump.
- What our technician checks
- Bleed-off flow is checked and the pads, pan and pump are inspected for scale that requires cleaning or replacement.
Blowing air that is not cool
- Likely causes
- Dry pads from a failed water pump, a clogged distribution line, a low float valve setting, or high outdoor humidity.
- What our technician checks
- The technician confirms the pump is running, checks the distribution tubes and spider for clogs, and verifies water level in the pan.
Water pump not running
- Likely causes
- A failed pump motor, a pump clogged with mineral scale, or a bad pump switch on the control.
- What our technician checks
- Voltage to the pump is tested and the pump intake and impeller are inspected for scale.
Musty or fishy smell
- Likely causes
- Old pads growing mold or algae, stagnant water in the pan, or a reservoir that has not been drained and cleaned.
- What our technician checks
- Pads are inspected for slime and mineral crust, and the reservoir is checked for sludge and standing water.
Water overflowing from the cooler
- Likely causes
- A stuck or misadjusted float valve, a cracked pan, or a bleed-off line that is open too far.
- What our technician checks
- The float valve is adjusted and tested for shutoff, and the pan and bleed line are inspected.
Blower squealing or slipping
- Likely causes
- A worn or loose drive belt, dry blower bearings, or a misaligned motor pulley.
- What our technician checks
- Belt tension and wear are checked, pulley alignment is confirmed, and bearings are spun for roughness.
Quick checks you can do safely
- Open a window or door slightly so air can flow out of the house.
- Check that the water supply valve to the cooler is open.
- Switch to pump only for a few minutes to wet the pads before running the fan.
- Look at the pads for dry streaks or heavy white crust.
- Confirm the cooler disconnect or plug is on.
Safety first: Water and line-voltage wiring share the same cabinet, so power must be off before reaching inside, and roof-mounted units require safe ladder and roof access.
