When the Gold Coast heat feels unbearable, the last thing you want is an air conditioner that only blows air without cooling. This issue is more common than you think and while it might seem like a major breakdown, it’s often caused by simple, fixable problems. Let’s explore the key reasons your air conditioner is blowing air but not cooling, and what you can repair it.

1. Common causes of an air conditioner blowing but not cooling
A. Wrong mode setting
It sounds obvious, but sometimes your air conditioner is set to “Fan” instead of “Cool.”
In fan mode, the system only circulates air without activating the cooling cycle. This can happen accidentally, especially if children or guests have access to the remote.
Quick fix: Check your remote for a snowflake symbol (❄). If the “Fan” icon is highlighted, switch to Cool mode.
B. Dirty or clogged filters
Gold Coast’s humid and coastal climate means dust and salt can build up faster inside your system. A dirty filter or indoor coil restricts airflow and reduces cooling efficiency, making it feel like your AC is only blowing warm air.
Quick fix: Clean or replace filters every 3–6 months. For homes near the beach, more frequent maintenance may be needed to prevent salt corrosion and dust build-up.
C. Low or leaking refrigerant (Gas)
If your system is low on refrigerant, it can’t absorb and release heat properly. You might also notice hissing sounds, ice on the coils, or your system turning off unexpectedly. Refrigerant leaks are not just a performance issue, they can also harm the environment and your compressor if ignored.
What to do: Call a licensed air conditioning repair service Gold Coast to test for leaks and refill refrigerant to manufacturer standards.
D. Outdoor unit (Condenser) not working
Your outdoor unit (often called the condenser) is responsible for releasing heat. If it’s not running or running weakly, no cooling can occur.
Common reasons include:
- Power supply issues or damaged wiring
- Blocked airflow around the condenser
- Faulty capacitor or compressor
- Prolonged operation under extreme temperatures (39–40°C)
What to do: Ensure there’s enough space around your outdoor unit and it’s shaded from direct sunlight. If it still doesn’t work, schedule a professional inspection.
E. Water leakage or drain blockage
If water is dripping from the indoor unit or pooling near the outdoor system, a blocked drain pipe may be preventing condensation from draining properly. This can cause the cooling process to slow or stop.
Quick fix: Check the drain line for visible clogs. For serious leaks, have a technician clean the line and inspect for mould or damage.
2. How to fix an air conditioner that blows air but isn’t cold
A. Reset cooling mode
Make sure your unit is set to Cool mode and the temperature is set 4–6°C below room temperature.
Keep the remote away from children to avoid accidental changes.
B. Schedule regular maintenance
Preventative maintenance keeps your AC performing efficiently all year round.
At DEEPCHILL, we recommend:
- Cleaning indoor and outdoor units every 6 months
- Checking refrigerant levels
- Testing electrical components
- Inspecting insulation and pipework
Regular maintenance not only prevents breakdowns but also extends your system’s lifespan and reduces energy costs.
C. Reposition or replace components if needed
If the outdoor unit is exposed to direct sunlight or hot walls, consider relocating it to a shaded area for better performance.
Also check electrical connections – burnt or damaged wires can reduce cooling output or even cause the system to stop working entirely.
D. Call a professional for diagnosis
If none of these fixes work, it’s time to call an expert. Untrained handling of refrigerants or electrical components can cause serious damage.
A certified air conditioning Gold Coast technician can quickly identify whether the issue is mechanical, electrical, or refrigerant-related.
