Why Swamp Coolers Are Still a Great Option

Swamp coolers, also called evaporative coolers, can make a huge difference in keeping your home comfortable on the hottest days of summer. In fact, many homeowners prefer this type of air conditioner compared to relying on a central AC unit during summer.

The reason for this is that a swamp cooler is highly efficient at taking extremely hot air and bringing the temperature down by 15° to 20°. If you want to learn more about a swamp cooler in San Juan County, NM, our team is here to help. You can keep reading to learn more about the benefits of swamp coolers for our area of the country.

How a Swamp Cooler Works

A swamp cooler is usually a larger, whole-home unit but can also come in a portable unit that creates cold air for your home in a unique way. A swamp cooler draws in hot air and removes the heat by using pads that are soaked with cold water. After the heat is absorbed by these pads, cooled air blows into your home. The qualifier for a swamp cooler working effectively is that it needs a consistent source of hot, dry air and enough water to keep the pad soaked throughout the cooling process.

You cannot use a swamp cooler with the windows and doors in your home closed. The air blowing from the swamp cooler will pressurize the home and block cool air coming into the home.  A whole home swamp cooler must be placed where it can constantly draw in hot air from the outside, usually on the roof, and be able to escape through windows or doors that are cracked open. The hotter the air, the more heat your swamp cooler needs to be removed, and the warmer your indoor temperature will be. 

Fresh Air

One major benefit of a swamp cooler is that you bring a lot of fresh air into your home. Since indoor air quality can be up to five times as polluted as outdoor air, this can greatly improve your family’s health. Of course, if you have an allergy sufferer in your home, you do want to take this into consideration. It’s possible that too much fresh air from outside could make allergy symptoms worse. Be aware that your home may also become dustier with the use of a swamp cooler.

Location, Location, Location

Since swamp coolers use water to cool the air, they do not work as well in more humid climates. If there is 50% or more humidity in the air, your swamp cooler will become less and less effective at cooling. Of course, for our area where the air is drier, a swamp cooler works great. In fact, experts estimate that a swamp cooler can lower the temperature in your home by as much as 20° on the hottest days of summer. That means if it is 95° outside, a swamp cooler can get your home as low as 75°.


A swamp cooler costs less to install than a full-fledged central air system. It may also cost less to operate depending on usage, so the savings could add up very quickly. Consider installing a digital cooler controller to help regulate your temperature with a swamp cooler and forget about having to remember to turn it off.
