Swamp cooler maintenance calendar for El Paso
A simple seasonal checklist to keep your cooler running.
Quick answer: Service a swamp cooler three times a year: spring start-up (pads, pump, float, belt, water line), mid-summer checks (water level, mineral buildup), and fall shutdown (drain, clean, disconnect water, cover). Turn off power before opening the cooler and follow your manufacturer’s manual.
Spring start-up
- Inspect the pads and replace any that are crusted, sagging, or musty.
- Clean the pan and check the float valve and water line for leaks.
- Check the pump and the distribution tubes for clogs.
- Check belt tension and condition, and lubricate if your manual calls for it.
- Reconnect water, fill the pan, and test the unit.
Mid-summer checks
- Watch the water level and look for mineral buildup.
- Make sure pads stay evenly wet.
- Crack a window or open a relief vent so air can leave the house.
Fall shutdown
- Drain the pan and supply line so they do not freeze.
- Clean away mineral scale.
- Turn off power and water to the unit.
- Cover the unit or seal the roof opening if recommended.
If the cooler is old and rusting, compare repair with conversion.
