Evaporative Cooler Versus Air Conditioner: Which Fits?
An evaporative cooler uses water and fresh-air movement; an air conditioner uses a refrigeration cycle. Climate, humidity and the need to ventilate are decisive.

The verdict
The evaporative cooler versus air conditioner choice turns on climate and operating needs. Evaporative cooling can suit dry conditions and fresh-air ventilation; air conditioning is more suitable when humidity control and closed-room temperature control are priorities.
Breezair is a fixed evaporative system designed to supply outside air through a whole-home installation.
A split system recirculates conditioned indoor air rather than relying on evaporative ventilation.
Air conditioning removes heat and moisture through its refrigeration process; direct evaporative cooling adds moisture.

Common questions
Questions before you buy
What is the difference between a swamp cooler and an air conditioner?
A swamp cooler is an evaporative cooler that uses water and airflow; an air conditioner uses a refrigeration cycle to remove heat. Evaporative systems add moisture, while air conditioning can dehumidify.
Is an evaporative cooler cheaper to run than air conditioning?
Running costs depend on equipment, local tariffs, operating hours and climate. Compare the exact system's published power and have a designer estimate expected use rather than relying on a blanket claim.
Can an evaporative cooler work with windows closed?
Direct evaporative systems need air to pass through the space and leave through a relief path. A closed room can retain moisture and does not match typical operating guidance.
Which is better in a humid climate?
Air conditioning is generally a more suitable choice when humidity reduction matters. Evaporative cooling adds moisture and is less effective when the air is already humid.
