If your Breezair evaporative air conditioner is running but your home doesn’t feel as cool as it used to, there is usually an underlying issue affecting the cooling process.
Poor cooling performance is one of the most common reasons Perth homeowners book a service call.
Fortunately, many Breezair cooling problems can be diagnosed quickly and are often resolved through maintenance or repairs.
How A Breezair System Cools Your Home
Breezair systems work by drawing warm outside air through wet filter pads.
As the air passes through the pads:
• Heat is absorbed
• Air temperature drops
• Fresh cooled air enters the home
For this process to work efficiently, the system needs:
• Adequate water supply
• Clean filter pads
• Proper airflow
• Correct water quality
• Functional pumps and motors
If any of these components are not operating correctly, cooling performance can suffer.
Dirty Filter Pads
One of the most common causes of poor cooling is dirty filter pads.
Breezair filter pads clip into the unit from the side and are designed to absorb and distribute water evenly.
Over time they can become contaminated with:
• Dust
• Dirt
• Scale buildup
• Mineral deposits
• Organic debris
When the pads become clogged, airflow is restricted and cooling efficiency drops.
In many cases, replacing worn filter pads significantly improves performance.
Faulty Water Pump
The water pump is responsible for circulating water from the reservoir to the filter pads.
If the pump fails:
• Pads remain dry
• Air is no longer cooled effectively
• Warm air may blow through the house
A failed pump is often mistaken for a major system fault when it is actually a relatively straightforward repair.
Stuck Solenoid Valve
The solenoid valve controls the water entering the evaporative cooler.
If the valve becomes stuck or fails:
• Water may not enter the system correctly
• The reservoir may not fill properly
• Cooling performance can decrease
Without sufficient water reaching the pads, the evaporative cooling process cannot function effectively.
Float Valve Problems
The float valve regulates water levels inside the reservoir.
If the float:
• Becomes stuck
• Is adjusted incorrectly
• Fails internally
the water level may become too low.
Insufficient water levels can reduce pad saturation and significantly impact cooling performance.
Poor Water Quality
Many Breezair models use advanced water management systems that include:
• Salinity probes
• Automatic drain systems
• Water quality monitoring
If water quality deteriorates, scale buildup can occur inside the system.
This may affect:
• Filter pads
• Water distribution
• Cooling efficiency
Maintaining appropriate drain and salinity settings helps keep the system operating effectively.
Motor Problems
The fan motor is responsible for moving air through the cooler and into the home.
If the motor begins to fail, homeowners may notice:
• Reduced airflow
• Poor cooling
• Intermittent operation
• Motor cut-outs
Older Breezair units often use AC belt-drive motors, while newer systems typically use DC motors.
Regardless of motor type, airflow problems will directly affect cooling performance.
Not Enough Fresh Air Escape
Evaporative cooling systems require ventilation.
Many homeowners mistakenly close all windows and doors when operating their cooler.
Without adequate air escape points:
• Humidity increases
• Airflow decreases
• Cooling efficiency suffers
Opening selected windows slightly allows fresh cooled air to circulate properly through the home.
Has Your Breezair Been Serviced Recently?
A lack of maintenance is often the biggest contributor to poor cooling performance.
Annual servicing helps identify:
• Dirty filter pads
• Pump faults
• Water quality issues
• Motor problems
• Drain system faults
Many cooling issues can be prevented through regular maintenance.
Signs Your Breezair Needs Attention
You should arrange an inspection if you notice:
• Poor cooling performance
• Increased humidity
• Reduced airflow
• Warm air from vents
• Unusual smells
• Water leaks
• Motor cut-outs
Addressing these issues early can often prevent more expensive repairs later.
