Summertime is here and you have your cooling system cranked up. However, you still feel uncomfortable in your home. You check your unit and it is working fine. Perhaps, you are using the wrong type of cooling unit for your climate. Should you be using a swamp cooler or air conditioner?

Swamp Cooler Pros and Cons

When we think swamp cooler (also known as evaporative coolers) we should think water. It not only takes a constant flow of water to operate a swamp cooler, but it also produces water as well in the form of humidity. So, naturally, swamp coolers are best for low humidity climates.


Swamp coolers are less expensive than their air conditioner counterparts and produce a lot less CO2 emissions. They are energy efficient, easy to install and provide humidity to dry and arid climates.


Swamp coolers should not be used in more humid climates because the increased humidity can lead to mould and mildew in the home. They also require more frequent maintenance, a regular source of water and a swamp cooler not lower the temperature as much as an air conditioner does. In fact, swamp coolers are either on or off. There is no thermostat to regulate temperature.

Air Conditioner Pros and Cons

Air conditioners reduce humidity. Therefore, using an air conditioner in more humid climates makes sense. Air conditioners may be used in drier climates but not recommended for arid climates.


Air conditioners are very efficient at cooling air and lower temperatures can be maintained. Also, it can be regulated to precise temperatures. Air conditioners assist with lowering humidity and window units are easy to install.


Air conditioners should not be used in arid climates. When the air is persistently too dry, health problems may arise regarding skin and eye hydration. Air conditioners require more energy to run and emit higher CO2 levels. They are also more expensive to maintain.


Clean filters are very important whether you choose either an air conditioner or a swamp cooler. Any type of forced air will bring debris. Dirty air conditioner filters bring dust, dander and pollen. Dirty swamp cooler pads bring mould and mildew spores. All are unhealthy for our respiratory system and can lead to breathing complications.
