Evaporative Cooler Cleaning Is More Than Washing the Pads
Cleaning is an important part of maintenance, but it shouldn't be treated as the entire service.
The water system is particularly important because an evaporative cooler repeatedly stores and circulates water.
Depending on the condition of the unit, cleaning may involve removing accumulated sediment, mineral scale and other buildup from areas such as the reservoir, water distribution components, pump and cooling media.
The reason this matters isn't just appearance.
Buildup can interfere with:
- Water flow
- Pump operation
- Water distribution
- Cooling-pad performance
- Drainage
- Overall system efficiency
The appropriate cleaning method also depends on the particular evaporative cooler and manufacturer's requirements.

A useful evaporative cooler service should go beyond switching the unit on and saying that it works.
The condition of the major operating components should be considered together.
Water System
The pump, water level, float valve, distribution system, reservoir and drainage all affect how effectively water reaches the cooling pads.
A problem in one part of this system can reduce cooling even when the fan is operating normally.
Cooling Pads
The pads provide the surface where evaporation takes place.
Over time they can collect mineral deposits, dirt and other material. They can also deteriorate with age.
The important question isn't simply "Are the pads old?" but whether they are still allowing water and air to pass through effectively.
Fan, Motor and Drive Components
The fan needs to move a sufficient volume of air through the wet pads and into the duct system.
Depending on the design, inspection may include the motor, belt, bearings, fan assembly and related components.
Changes in sound, vibration or airflow can provide useful clues about the condition of these parts.
Ductwork and Airflow
A cooler can be working properly at the roof unit while the rooms inside the house receive poor airflow.
Restricted, damaged or disconnected ductwork can affect the amount of cooled air reaching different parts of the home.
This is particularly worth investigating when some rooms are comfortable but others remain hot.
Controls and Operation
The controller, switches and operating modes also need to work correctly.
A system that starts and stops unexpectedly, won't select the appropriate mode or doesn't respond correctly may have a control or electrical issue requiring further investigation.
What We Look At During an Evaporative Cooler Service
Water Hygiene and Evaporative Coolers
An evaporative cooler is different from a split system because water is an operating part of the cooling process.
Whenever a system stores and circulates water, good maintenance and water management are important.
Sediment, scale, organic material and biofilm can accumulate in poorly maintained water systems. Keeping the water components clean and properly maintained helps reduce conditions that may support unwanted microbial growth.
This is one reason PACS treats the water system as an important part of evaporative cooler maintenance rather than concentrating only on the fan and cooling pads.
What about Legionella?
Legionella bacteria can grow in certain water environments, particularly where conditions allow bacteria to multiply. Legionnaires' disease is associated with inhaling contaminated water droplets or aerosols.
That does not mean every household evaporative cooler is a significant Legionella source, nor can routine servicing be described as preventing Legionnaires' disease.
The sensible approach for homeowners is to follow the manufacturer's maintenance instructions and keep the water-containing components of the system properly maintained.
The worst time to discover a problem is often the first major heatwave of the season.
After sitting unused through winter, an evaporative cooler may have:
- A pump that no longer operates correctly
- Deteriorated cooling pads
- A worn belt
- Mineral buildup
- Blocked water distribution
- Drainage problems
- A motor or electrical fault
- A problem that wasn't obvious when the system was last used
A pre-summer inspection gives you an opportunity to identify these issues before the system is required every day.
For older systems, it can also be useful to determine whether a component needs replacement before summer rather than waiting for a breakdown.
Getting Your Evaporative Cooler Ready for Perth Summer
Frequently Asked Questions
How long does an evaporative cooler normally last?
The lifespan varies depending on the system, installation, water quality, usage and maintenance history. Well-maintained systems can operate for many years, but individual components such as pads, pumps, motors and belts may need replacement during the life of the unit.
Can I run an evaporative cooler with all my windows closed?
Generally, no. Evaporative cooling needs somewhere for the incoming air to exit the home. Closing the house completely can restrict airflow and significantly reduce cooling performance.
The exact amount of opening required depends on the house and the system.
Why does my evaporative cooler work well some days but poorly on other days?
Outdoor humidity is a major factor. Evaporative cooling is most effective when the air is hot and dry. When humidity is high, evaporation becomes less effective and the cooling output can decrease.
This is one reason Perth's dry summer climate is particularly suitable for evaporative cooling.
Does an evaporative cooler use a lot of water?
Evaporative coolers consume water because evaporation is part of the cooling process. Water usage varies depending on the system, weather conditions, operating hours and water management system.
Some systems also periodically drain or flush water as part of their operation.
Can I leave my evaporative cooler running all day?
Evaporative coolers can operate for extended periods when properly installed and maintained, but actual suitability depends on the system, weather conditions and manufacturer's recommendations.
During extremely humid conditions, running the system continuously may provide less cooling benefit.
What happens if the evaporative cooler's pump stops working?
The fan may continue operating, but without sufficient water reaching the cooling pads, the system will provide little or no effective evaporative cooling.
A failed pump should be inspected and repaired or replaced as appropriate.
Can an old evaporative cooler be repaired?
Often, yes. The decision depends on the age and condition of the system, availability of parts and the nature of the fault.
For an older system requiring several major components, replacement may make more financial sense than continuing with repairs.
Why does my evaporative cooler smell?
A smell can come from accumulated dirt, mineral deposits, organic material, stagnant water or other contamination within the water and airflow system.
A proper inspection can help identify where the smell is coming from rather than simply masking it with a fragrance or deodoriser.
Does hard water affect an evaporative cooler?
It can. Minerals in hard water can accumulate on cooling pads, pumps, water distribution components and other parts of the system.
Over time, mineral scaling can affect water distribution and cooling performance, which is one reason regular inspection and cleaning are useful.
Can an evaporative cooler cause too much humidity inside my house?
Evaporative cooling adds moisture to the incoming air. Under normal dry conditions, this is part of how the system provides cooling.
If the home does not have sufficient exhaust airflow, or if outdoor humidity is already high, indoor humidity can become excessive and the system may not perform as effectively.
Is an evaporative cooler suitable for every Perth home?
Not necessarily. Evaporative cooling is particularly well suited to dry conditions, but the property's design, insulation, ductwork, airflow, room layout and homeowner requirements all matter.
A home should have suitable airflow pathways for the system to work properly.
Should I replace the cooling pads every year?
Not necessarily. Pad replacement depends on their condition rather than simply their age.
If pads are heavily scaled, deteriorated, damaged or no longer performing properly, replacement may be appropriate. Otherwise, cleaning and maintenance may be sufficient.
Can an evaporative cooler be used for heating?
Standard evaporative coolers are designed primarily for cooling and are not equivalent to a reverse-cycle air conditioner for heating.
If you require both heating and cooling, a separate heating system or reverse-cycle air-conditioning solution may be worth considering.
Should I service my evaporative cooler before summer?
Yes, this is a practical time to do it. Having the system checked before heavy summer use gives you an opportunity to identify issues with the pump, pads, water system, fan, motor, drainage or controls before you need the cooler during a heatwave.
