Swamp coolers can be removed due to issues that may arise after they have gotten old or because the homeowner wants to modernize their cooling system. After a while swamp coolers can run into problems such as corrosion and water damage, not cooling the home sufficiently, and water leaks.

Can you leave a swamp cooler on all day?

You can run your swamp cooler all day should you so choose without seriously increasing your monthly utility bill. However, you will need to be available to refill the reservoir in the interim. Should you not want to do that, run your swamp cooler first thing in the morning or overnight to fill your home with cool air.

Why are swamp coolers bad?

Swamp coolers do have the potential to harbor mold and mildew. The pads do stay wet through the season, which means that mold could grow. In more humid weather, mold is more apt to grow. When you turn on the cooler, the mold in the device could be spread through the process of blowing the air out into the ducts.
