As Perth begins warming up in spring, many homeowners prepare to switch their Coolbreeze evaporative air conditioner back on after months of sitting idle through winter.
While it can be tempting to simply press the ON button and hope for the best, a few simple checks can help avoid breakdowns, improve cooling performance, and ensure your Coolbreeze is ready for the summer ahead.
At Air Legends, September and October are some of our busiest months because many homeowners discover faults the first time they attempt to use their evaporative cooler after winter.
Here’s how to prepare your Coolbreeze for another Perth summer.
Why Your Coolbreeze Needs A Spring Check
During winter your evaporative air conditioner sits exposed to:
• Rain
• Wind
• Dust
• Moisture
• Debris
Even if a winter cover has been installed, the system can still develop issues while not operating.
A spring inspection can help identify:
• Worn filter pads
• Pump failures
• Solenoid valve faults
• Drain valve leaks
• Controller issues
• Water distribution problems
before the first heatwave arrives.
Step 1 – Remove The Winter Cover
If your Coolbreeze has a winter cover fitted, remove it before operating the system.
Inspect the cover for wear and store it somewhere dry ready for next winter.
Never operate the evaporative cooler with the winter cover still installed.
Step 2 – Inspect The Filter Pads
Filter pads are critical to cooling performance.
Check for:
• Heavy staining
• Sludge build-up
• Physical damage
• Mould growth
• Excessive scale
Well-maintained pads can often last between 7 and 10 years, although this varies depending on water quality and servicing history.
If the pads are heavily deteriorated, replacement may be recommended.
Step 3 – Check For Water Leaks
Water leaks are one of the most common issues found during spring start-ups.
Pay particular attention to:
• Drain outlets
• Drain valves
• Pipework
• Water connections
A leaking drain valve O-ring can waste significant amounts of water if left unattended.
Step 4 – Test The Water System
When the unit is turned on, water should flow evenly across all filter pads.
Poor water distribution may indicate:
• Blocked spreaders
• Pump problems
• Solenoid issues
• Scale build-up
Without proper water flow, the evaporative cooler cannot operate efficiently.
Step 5 – Check The Pump
A common Coolbreeze fault occurs when the fan operates normally but the air is no longer cool.
This often indicates a pump issue.
If the pump is not circulating water correctly, the system may feel like a large ceiling fan rather than an evaporative cooler.
Step 6 – Test The Controller
Check all controller functions including:
• Fan speeds
• Cooling mode
• Water operation
• Timer functions
• Display operation
Sometimes the evaporative cooler is functioning correctly but the controller or keypad has developed a fault during winter.
Step 7 – Listen For Unusual Noises
When starting the system for the first time, listen carefully.
Warning signs include:
• Grinding noises
• Excessive vibration
• Rattling sounds
• Motor issues
These may indicate worn components requiring attention.
Common Coolbreeze Problems Found In Spring
Some of the most common faults we find after winter include:
Failed Pumps
The fan runs but cooling performance disappears.
Faulty Solenoids
Water does not enter the system correctly.
Drain Valve Leaks
Water continuously drains from the unit.
Worn Filter Pads
Reduced airflow and cooling performance.
Controller Problems
The system does not respond correctly to commands.
Why Spring Servicing Is Worthwhile
Booking a service before summer arrives can help:
✔ Improve cooling performance
✔ Reduce water wastage
✔ Extend equipment life
✔ Reduce breakdown risk
✔ Identify faults before hot weather arrives
✔ Improve reliability throughout summer
Many homeowners wait until the first hot day of the season before checking their system, often resulting in longer repair delays.
The Ideal Time To Service A Coolbreeze
For most Perth homeowners, September and October are the best months to prepare an evaporative air conditioner for summer.
This provides time to identify and repair faults before temperatures rise significantly.
