Evaporative (swamp) cooler service in Albuquerque

Swamp coolers are still a practical fit for the high desert if they are started, maintained, and shut down with the seasons. Dry air is what makes them work; a neglected pad or pump is what makes them smell or drip into the house.

Why they are still common here

Evaporative cooling uses much less electricity than refrigerated air and works well when outdoor humidity is low. Many Albuquerque and Rio Rancho houses still run a roof-mounted cooler for all or part of the summer. They do not cool as well during a humid monsoon afternoon, and they add moisture to the house — which is sometimes welcome, sometimes not.

Seasonal startup

A typical spring start includes inspecting or replacing pads, checking the pump and float valve, confirming the bleed-off or dump is working, looking for rust or leaks in the pan, and making sure the hatch and ducts seal. A “start-up” that is only a water hookup and a flip of a switch often misses a worn pad or a sagging cooler that will leak later.

Mid-season problems

  • Musty air usually points to old pads, standing water, or a pan that is not draining.
  • A dry cooler or a trip to the water bill can be a stuck float, a leak, or a pump that has failed.
  • Weak airflow can be a slipping belt, a failing motor, or ducts that were never balanced.

Fall shutdown

Drain and dry the pan, shut the water, and cover or service the unit so it does not sit wet through winter. If you are thinking about converting to refrigerated air, get more than one written bid and confirm duct and electrical capacity — it is a different system, not a pad change.
