What are the differences between an air conditioner and evaporative cooler? Expert Answers
If you are wondering, “What are the differences between an air conditioner and evaporative cooler?” you’ve come to the right place for the answer.
HVAC professionals have long debated the advantages of various air cooling systems and their applications. Today, however, with sky-rocketing utility costs, dwindling energy resources, and environmental concerns, alternatives to traditional cooling have come to the forefront of the industry, especially with so many of us spending long hours in conditions where air conditioning is impractical.
Across the world, millions of workers – including those in agricultural, construction, industrial, automotive, and warehouse industries – are exposed to the possibility of heat stress each day. Those individuals all deserve a safe and comfortable environment.
Let’s discuss the differences between these two methods and which is right for your situation.
What Are The Differences Between An Air Conditioner And Evaporative Cooler?
Generally, air conditioners use chemical refrigerants to remove heat and moisture from inside a space. They use a fan to distribute the conditioned air to both improve thermal comfort and indoor air quality.
Most commonly, they are fixed, ducted systems and require a minimum of bi-yearly maintenance by a professional to operate optimally.
In this type of system, air is cooled in coils by chemical means, and the heat and moisture are dissipated outdoors. Air conditioners work best in fully enclosed environments and can reduce temperatures to an exact, selected ambient temperature, regardless of outdoor conditions.
The biggest drawback to these systems is cost – not only can installation cost thousands of dollars upfront, but month-to-month operating costs can also run in the hundreds of dollars.

Evaporative Cooling Systems
Evaporative cooling systems (sometimes referred to as swamp coolers or desert coolers) require fewer materials to operate – typically only water and electricity. Evaporative systems typically require less maintenance than air conditioners, which can produce considerable savings over the course of a year. While evaporative coolers do use water to cool naturally, they do not produce any mist, fog, or spray water.
Portable Evaporative Air Coolers
Evaporative coolers use some sort of water-soaked media that a fan pulls air through. When the air is pulled through the media, it interacts with the water, and heat molecules are scrubbed from the air, resulting in cooler, slightly moistened air.
They work best in open environments, with plenty of access to fresh air. Evaporative coolers can rarely be used in enclosed environments. Also, temperature reduction cannot be selected, but is based on ambient conditions.
While fixed evaporative cooling systems can be a bit more expensive to install (most portable evaporative coolers are ready to use out of the box), operation costs are minimal – often as low as a $1 a day – making them much more energy efficient than air conditioning.
Is Evaporative Cooling Right for You?
There are many factors to consider when choosing cooling systems for structures or outdoor use. One of the first – and most important – things you must determine is if the environment has access to fresh air or if it is enclosed.
For example, if you work in a warehouse where the doors are open most of the day, air conditioning is not a viable option, as you are letting all of your expensively cooled air escape. However, if you are in an office setting where no windows open and doors stay closed, evaporative cooling is not going to work very well and may even make the environment MORE uncomfortable by adding too much moisture to the air.
To bust one myth, many people will tell you that evaporative cooling only works in dry climates. While evaporative coolers achieve significant temperature drops in more arid climates and drier spaces, they can and do provide relief from the heat in any climate due to the advancements in evaporative cooling technology.
These aren’t the swamp coolers of years ago!
Even in hot and humid areas, such as Houston, you can still expect to see 10°F-13°F cooling. (We know this for a fact – we are located in the small East Texas town of Center and know hot and humid. We use our own products to keep our manufacturing employees safe and comfortable for more than half the year! Really, we do – you can read our story here!)
Now we’ve answered the question, “What are the differences between an air conditioner and evaporative cooler?” It’s important to note that due to numerous improvements, evaporative cooling is definitely a contender in a far greater array of applications than it has been historically.
