How to winterize a swamp cooler

In many homes, home cooling is provided by a swamp cooler rather than standard air conditioners. Also known as an evaporative cooler, a swamp cooler is simple and energy-efficient, cooling the air by letting the water absorb the heat from surrounding air as it changes from liquid to gas. But although a swamp cooler has low maintenance requirements, it needs to be winterized at least once a year to operate efficiently.

3 Reasons Why You Need to Winterize Your Swamp Cooler

Winterizing your swamp cooler has several benefits:

  • Prevents condensation and rust damage
  • Prevents freezing of water line and subsequent replacement during the coming spring
  • Prevents cooler vent heat loss

The following are the steps to follow when preparing a swamp cooler for winter:

  • Shut and disconnect the water supply line.
  • Drain all the standing water at the swamp cooler’s base to prevent corrosion and potential damage over the winter period.
  • Use the sponge to clean the dirt and grime on the inside walls of the swamp cooler.
  • Replace the evaporative pads
  • Install a winter cover to protect the cooler from the elements during the winter period.
  • Cover the vent where the cooler air blows air into your home. This prevents heat loss during the winter and helps in the swamp cooler saving.

Your swamp cooler is now ready for winter. Remember to reverse the process in the coming spring to prepare it for the summer period.

Winterizing a swamp cooler is very important to ensure you get the most out of it. With the above guide, you can help prevent damage, boost efficiency and ensure it serves you for longer.
