In detail
Why Your Air Conditioner Blows Warm Instead of Cold in Craigmore
Warm air almost always means the cold part of the system has stopped working, not the whole unit. The fan keeps running either way, so the symptom feels worse than the fault often is. Here are the causes we see most, cheapest first.
Thermostat set wrong
It happens more than you would think, especially in homes where one controller runs a ducted system. We get calls across Craigmore where the unit is simply set to heat or fan, and the fix takes two minutes.
Choked filter or coil
Adelaide's dry summers push fine dust indoors, and a blocked filter starves the coil until it cannot absorb heat. The fan still runs, so warm air keeps coming out while the room never cools.
Low refrigerant charge
Gas does not wear out, it escapes through a leak. A system running short ices the coil and blows warm, and the leak needs finding and fixing before a recharge, not just topping up.
Compressor or capacitor
The outdoor unit hums but the compressor never kicks in, so the fan circulates room-temperature air. Capacitors fail often on second and third-generation units in the older Trust-era pockets, and it is a common one-visit repair.
Duct faults
Warm air from every vent can mean a split duct or a crushed run in the ceiling. Single-storey brick-veneer homes make access straightforward, and we check the runs before quoting anything.

Safe Checks Before You Call
A few minutes with the thermostat, filter and outdoor unit rules out the cheap causes. Try these first, because if the fault is one of them, you have saved yourself a call-out.
Check the thermostat
Confirm it is on cool, not heat or fan, and the target temperature is below the room reading. It sounds obvious, and it ends more warm-air calls than any other single cause.
Look at the filter
Pull the filter from the return grille and hold it up to the light. If you cannot see through it, wash it, let it dry fully and refit it before running the unit again.
Inspect the outdoor unit
Clear leaves and grass away from the outdoor unit and check it is actually running. A unit sitting still while the indoor fan blows means a compressor or capacitor problem that needs a technician.
Checklist
When Warm Air Means a Split System Repair
Some faults should not wait. Switch the system off at the wall and call us if you spot any of these:
- The outdoor unit will not start at all
- Ice building up on the coil or the refrigerant lines
- Any burning or electrical smell from the unit
Running a low-gas or frozen unit risks the compressor, and that turns a small repair into a replacement. Heatwaves are when it matters most, because consecutive days over 40 push every system in the street to its limit.
Urgent faults get our Within-the-Hour Response, where availability allows, and we run 24/7 emergency availability.
How it works
How We Fix Your Cooling
Every warm-air job follows the same honest sequence, and the price is settled before any work starts.
- 01
Find the fault
We test airflow, gas pressure, electricals and the controller to pinpoint the cause. Diagnosing properly first means you never pay for a part the system does not need.
- 02
Quote before work
Fixed Upfront Pricing means the price is set before anyone lifts a tool. No hourly rates and no bill shock, whatever the fault turns out to be.
- 03
Repair and test
Most warm-air faults are fixed on the first visit because our vans carry the common parts. We run the system through a full cooling cycle before we leave.
- 04
Stand by the work
The Lifetime Labour Warranty covers workmanship, so if a fault comes back because of our work, we return and fix it at no cost.

Blowing Warm Air FAQs
Why is my aircon blowing warm on a hot day?
Most often the thermostat is set wrong, the filter is blocked, refrigerant is low, or the compressor has stopped pumping, and we can tell which within one visit, usually on the same day.
Can I keep running my system while it blows warm?
Switch it off at the wall, because running a low-gas or frozen unit can damage the compressor, and a few minutes off now often saves a much bigger repair bill later.
How much does it cost to fix warm air from an air conditioner?
Every job is quoted under our Fixed Upfront Pricing, so you know the full cost before we start, and small fixes like a capacitor cost far less than a compressor.
Is low refrigerant the same as a gas leak?
Yes, refrigerant escapes through a leak rather than wearing out, so we locate and repair the leak, recover and recharge the gas legally, and test the system holds before we leave.
