Swamp Cooler vs. Air Conditioner: Should I Use Them Together in My Home?

A swamp cooler and air conditioner use opposite methods to control the temperature in your home. While a swamp cooler adds moisture to the air that cools your home, an air conditioner removes moisture from the air before releasing the dry, cool air into your home. The two methods cancel each other out and cannot be effectively used together.

How a Swamp Cooler Works

Swamp coolers work best in areas with low humidity. The coolers, also called evaporative coolers, take in warm air from your home and pass it over a wet pad. Moisture is added into the air to cool it then released back into your home. You need to continuously add water to the swamp cooler to ensure it works optimally. Swamp coolers don’t work well in high humidity areas, and their effectiveness diminishes quickly in such areas.

How Air conditioner Works

Air conditioners are not affected by external conditions like humidity. A central air conditioning system can effectively control the temperature in your entire home. The air conditioner takes warm air into the system, removes moisture from the air, and blows back the cool, dry air into your home. The cool air makes your home comfortable.


Swamp coolers can be more affordable. They come as window mounted or whole home swamp coolers that you can either mount on the roof or ground. Ground-mounted coolers are popular. However, roof-mounted coolers are tough to install but efficient. Swamp coolers that can perform up to 40 air changes per hour and an average of 30 are ideal. Also, make sure the C.F.M is 1000 per ton.

Air conditioners are used in most homes and are known to be more effective. Installing and upgrading your air conditioner will require professional help. Your home may need a duct or ductless system or a central air conditioner, and you can get your whole house installed.

You can only use one of these two cooling systems at a time since the two systems use opposite methods in cooling. Using one method also helps to lower your utility cost.
