Pros and cons
Pros:
• Costs less to install in some instances.
• Costs less to run. (careful some can have 1600w fans! that isn't necessarily cheap tor run)
• Allows you to vent heat from the house if it cools down outside by drawing in cool ambient air.
Cons:
• Increases humidity.
• They can only cool relative to that day’s dew point.
• Generally require slightly more maintenance than air conditioning.
• Consider carefully before purchasing in water restricted areas or where dependant on limited water as water consumption can be up to 80 litres per hour.
An evaporative cooler requires doors or windows open to allow airflow. As a guide, the entire volume of the room should be flushed through every two minutes (or around 30 air changes per hour).
During winter, older ducted units on the roof should have covers placed over them and ceiling vents closed to stop heat loss. Alternatively, consider purchasing a unit with a motorised damper. (many new units have a automatic spring or gravitational shutter)
