Traditional AC Units vs. “Swamp” Coolers

There are several options for cooling your home in Arizona, and most use a fairly similar method: forced air. Evaporative coolers, or “swamp” coolers, are the most unique as they don’t create cool air in the same way.

Here’s a breakdown of how swamp coolers differ from traditional central air conditioning systems.

Cooling Method

Evaporative coolers use the natural ability of dry climates to regulate moisture in the air. Air moves over wet cooling pads in the unit, adding moisture and reducing the temperature. This air moves into your home and the warm air escapes through open windows or ceiling ducts.

According to the Department of Energy, the cooled air can be between 15 and 40 degrees lower than the outdoor temperature.

Traditional air conditioning units use refrigerant, a chemical that reacts with the air to cool it down and then a fan blows that cool air through ducts and vents into your home.

Operation and Maintenance

Evaporative coolers are less expensive to install and run, making them a popular choice for those looking to reduce energy consumption. However, they do require a bit more maintenance, as they require monthly attendance to drain water and clean the unit. The maintenance isn’t difficult, but you’ll want to set a routine to ensure it gets done, or your efficiency and air quality could suffer.

You’ll also need to manage your windows to ensure warm air is able to escape.

Traditional air conditioning is different—you should always keep windows closed to allow cool air to remain inside. Plus, maintenance is mostly cleaning and replacing the air filter.
