What a Cooling Fault Actually Looks Like
The unit hums along, the fan spins, and the air from the vents never drops below the temperature already in the room. Sometimes the airflow feels weak, sometimes the system short-cycles.
The timing tells its own story:
- Cools fine in the morning, gives up by mid-afternoon
- Weak airflow from vents that used to push hard
- Runs constantly without pulling the room down
On the single-storey brick-veneer homes that dominate this suburb, that pattern usually points to airflow or refrigerant rather than a dead system. Our split system and repairs pages cover the fix side in more detail.
In detail
Likely Causes, Cheapest First
Most no-cooling callouts come down to one of four things, and the cheap ones are the most common:
Dirty filters
The established gardens on the original Castieu Estate allotments shed pollen and dust all summer, and your return-air filter catches every bit of it. When it clogs, cool air stops moving.
Choked coils
The outdoor coil needs clear airflow to dump heat, and leaf litter or a stored box against the unit starves it. A hose and half a metre of clear space around the unit often restore cooling on the spot.
Low refrigerant
Refrigerant does not wear out, so low gas means a leak somewhere in the coil or line set. Only a technician holding a full refrigeration licence can legally find it, recover what is left and regas the system.
Failed capacitor
A capacitor gives the compressor and fan their start-up kick, and Adelaide's dry heat is hard on them. When one fails, the indoor unit may blow air while the outdoor unit sits silent.

Safe Checks Before You Call for Air Conditioning Repairs
Three checks cost you nothing and rule out the simple stuff:
- Slide out the return-air filter and hold it up to the light. If you cannot see through it, clean or replace it.
- Confirm the controller is on cooling, not fan-only, and the set point is below room temperature.
- Walk outside and check the outdoor unit is running, clean and unobstructed.
If all three check out and the air is still warm, stop there. The remaining causes need licensed hands.

When to Call Our Aircon Team
Refrigerant, capacitors and wiring are not DIY territory, and guessing usually turns a small repair into a big one. Call us if you notice any of these:
- The outdoor unit is silent while the indoor unit runs
- Ice on the pipes or the indoor coil, which often pairs with water leaking inside
- The breaker trips every time the system starts
- The unit cools briefly, then drops back to warm air

Why a Cooling Fault Gets Worse in a Heatwave
Adelaide's dry heat means a heatwave here is consecutive days over 40, and a system with low refrigerant or a struggling compressor often dies on day two of one. A fault found in November is a cheap repair; the same fault found in February is an emergency call.

Air Conditioner Not Cooling FAQs
Why is my air conditioner running but not cooling?
Usually a dirty filter or coil choking airflow, a failed capacitor, or low refrigerant from a leak, and we can tell which one it is after one proper diagnostic visit.
Can I fix a cooling problem myself?
You can safely check the filter, the mode setting and the outdoor unit for blockages, but refrigerant, capacitors and wiring are licensed work, and touching them risks a bigger repair bill.
How quickly can you attend a no-cooling callout?
Urgent faults get a within-the-hour response where availability allows, and we run 24/7 emergency availability, so a dead system in a February heatwave does not leave your family waiting days.
Is an old unit worth repairing or should it be replaced?
Age, repeat part failures and repair quotes that stack up against a new system all point to replacement, and we will walk you through the numbers before you decide anything.
