When Cooling Stops: Why Your Unit Blows Warm
A unit that runs but never cools is telling you something specific. Nine times out of ten it is one of the causes below, and the cheapest ones are the most common.
Thermostat set wrong
Someone has bumped the mode to heat or the fan setting to vent, which happens more than you would think. Check the mode and temperature before anything else, because the fix costs nothing.
Choked filter or coil
The brick-veneer homes that fill the gully went up through the sixties, seventies and eighties, and their units work hard through dry, dusty Adelaide summers. A filter or coil caked in dust blocks airflow, the coil ices over, and the room never drops.
Refrigerant leak
Low gas means the system cannot absorb heat, so it circulates air at close to room temperature. Oily residue around the pipework joints is a common giveaway, and a leak needs locating and repairing, not just a top-up.
Compressor failure
The compressor is the heart of a refrigerated system, and when it wears out or fails electrically the unit becomes a fan. We test it properly on site and tell you honestly whether repair or replacement makes more sense.
Duct problems
On ducted systems, a crushed, disconnected or torn duct in the ceiling pushes warm roof-space air into the rooms instead of cooled air. Sloping blocks at the foot of the Adelaide Hills make some ceiling runs awkward, which is exactly how ducts work loose over the years.
Checks You Can Try Before You Call
A few minutes with the remote and the filter can save you a call-out, and none of these steps risk damage:
- Confirm the remote is on cooling mode, with the set temperature well below room temperature.
- Open the indoor unit and slide out the filter. If it is grey with dust, wash it, dry it and refit it.
- Walk outside and check the outdoor unit is running, not just humming, and clear leaves away from it.
- Give a frozen coil a few hours with the system off. Ice needs time to melt before the unit can breathe again.
If the unit still blows warm after all that, the fault is inside the refrigerant circuit or the compressor, and that is our job.

Questions
Air Conditioner Blowing Warm Air FAQs
Why is my air conditioner running but not cooling?
Usually a choked filter or coil, a refrigerant leak or a compressor that has dropped output, and we find which one on site before quoting the repair.
Can a refrigerant leak be repaired?
Yes, we locate the leak, repair it, then recharge the system, because topping up gas without fixing the leak only buys you a few weeks.
Should I switch the system off while I wait?
Yes, because a unit short on gas or starved of airflow strains the compressor the longer it runs, and that can turn a small repair into a replacement.
