Breezair is one of Australia’s most recognised evaporative cooling brands and is found in thousands of Perth homes.
Known for their efficient cooling performance, advanced controllers and water management systems, Breezair units are generally reliable when maintained correctly.
However, like any evaporative air conditioner, they can develop faults over time.
Understanding the most common Breezair problems can help homeowners identify issues early and avoid costly breakdowns during Perth’s hottest months.
How Breezair Systems Work
Breezair evaporative coolers draw warm outside air through water-saturated filter pads.
As the air passes through the pads:
• Heat is absorbed
• Air temperature decreases
• Fresh cooled air enters the home
Many modern Breezair models also include:
• Touchscreen controllers
• Motorised drain systems
• Salinity control settings
• Automatic water management
• Energy-efficient DC motors
While these features improve performance, they can also create additional components that require maintenance and occasional repair.
Breezair Not Cooling Properly
One of the most common complaints is poor cooling performance.
Possible causes include:
• Dirty filter pads
• Faulty water pumps
• Stuck solenoid valves
• Incorrect water levels
• Poor maintenance
When the filter pads are unable to absorb water properly, cooling efficiency drops significantly.
Many cooling issues can be resolved during a routine service.
Dirty Or Worn Filter Pads
Breezair filter pads are designed to clip into place from the side of the unit.
Over time they can accumulate:
• Dust
• Dirt
• Minerals
• Scale buildup
• Organic debris
As contamination increases, airflow and cooling performance decrease.
In many cases, replacing worn filter pads restores performance and improves indoor comfort.
Motor Failure
A failed motor is another common issue, particularly in older units.
Signs may include:
• Reduced airflow
• No airflow
• Intermittent operation
• Motor cutting out
• Unusual noises
Many older Breezair systems use AC belt-drive motors, while newer models use high-efficiency DC motors.
If one of the motor windings becomes open circuit, replacement is usually required.
Drain System Problems
Many Breezair models feature automatic motorised drain systems.
These systems help remove water from the reservoir at scheduled intervals to improve water quality and reduce scale buildup.
Problems can occur if:
• Drain valves fail
• Settings are incorrect
• Debris blocks drainage
• Components become worn
Drain issues can contribute to poor water quality, increased scale buildup and reduced cooling performance.
Salinity Control Issues
Modern Breezair systems use salinity probes to monitor water quality.
The controller can automatically dump water when salinity levels become too high.
If salinity settings are not configured correctly, homeowners may experience:
• Excessive water usage
• Increased scale buildup
• Reduced filter pad life
• Lower cooling efficiency
Fortunately, these settings can usually be checked and adjusted during servicing.
Controller Problems
Many newer Breezair units use electronic touchscreen controllers.
Occasionally homeowners may experience:
• Blank screens
• Unresponsive controls
• Error messages
• Communication faults
While controller faults are less common than mechanical issues, they can prevent the system from operating correctly.
Water Leaks
Water leaks can occur for several reasons including:
• Faulty float valves
• Drain problems
• Damaged filter pads
• Overflow conditions
Leaks should be investigated promptly to prevent damage to roof spaces and ceilings.
Why Annual Servicing Is Important
Most Breezair problems develop gradually and can often be identified during routine maintenance.
A professional service typically includes:
• Reservoir cleaning
• Drain inspection
• Filter pad assessment
• Pump testing
• Motor testing
• Controller checks
• Water quality inspection
Regular servicing helps maintain cooling performance while reducing the likelihood of unexpected breakdowns.
