When your air conditioner stops cooling in the middle of a Brisbane summer, the house becomes unbearable within hours. Our ARCtick-licensed technicians diagnose and repair every type of residential and commercial air conditioning system — split, multi-head, ducted, reverse cycle and package units — across Brisbane and South East Queensland.
We carry a well-stocked van of common capacitors, contactors, sensors, fan motors, PCBs and refrigerant, which means the majority of faults are fixed on the first visit rather than turning into a two-week parts saga. Where a part does need ordering, we tell you the honest lead time and cost up front.
We also give you a straight answer on the question every customer really wants answered: is this worth repairing, or are you throwing good money after bad? If your unit is fifteen years old, running R22 refrigerant and needs a compressor, we’ll tell you that replacement is the smarter spend rather than quietly taking the repair fee.
Common faults we repair
- Unit runs but blows warm air, or barely cools
- Refrigerant leaks and low gas charge
- Water leaking from the indoor unit onto walls or floors
- Ice forming on the indoor coil or pipework
- Outdoor unit not starting, humming, or tripping the circuit breaker
- Loud rattling, grinding, squealing or vibration
- Error codes on the wall controller or flashing indicator lights
- Remote control or thermostat not responding
- Fan running but compressor not engaging
- Burning, musty or chemical smells from the vents
- Ducted system cooling some rooms but not others
- Zone motors and dampers not opening or closing
Benefits of Professional Repair
- Accurate diagnosis first — we find the actual root cause rather than topping up gas on a system that has a leak, which is both wasteful and illegal to do repeatedly without repair.
- Same-day and next-day availability for most Brisbane suburbs, with priority slots during heatwaves.
- Fully licensed work — ARCtick refrigerant handling and QBCC-licensed electrical, protecting your safety and your warranty.
- Fixed pricing before we start — you approve the repair cost before any work is done.
- Genuine or approved-equivalent parts with a workmanship warranty.
- Honest repair-versus-replace advice backed by the actual age, refrigerant type and part cost of your unit.
- Restored efficiency — a correctly repaired system often drops power consumption noticeably, since faults like low charge and dirty coils force the compressor to work far harder.
Our Repair Process
Phone triage and booking
We ask about symptoms, error codes, unit age and brand. Some issues (tripped isolator, blocked filter, incorrect mode setting) we can help you resolve on the phone at no cost. Otherwise we book the earliest suitable slot.
On-site diagnosis
The technician inspects both indoor and outdoor units, reads error codes, tests electrical components with a multimeter and clamp meter, checks refrigerant pressures, superheat and subcooling, measures the temperature split across the coil and inspects airflow, filters and drainage.
Written quote and approval
You receive a clear explanation of what has failed and why, the cost to repair, and where relevant a comparison against replacement. Nothing proceeds without your approval.
Repair carried out
Most common faults — capacitors, contactors, fan motors, sensors, control boards, drain blockages, leak repairs and regas — are completed on the spot. Where a leak is found, we locate and repair it, pressure test, evacuate and recharge to the manufacturer’s weighed charge rather than simply topping up.
Testing and verification
We run the system through a full cycle, re-measure pressures and temperature split, confirm the fault is cleared and check that drainage and airflow are correct.
Report and prevention advice
You get a summary of what was done, the warranty on parts and labour, and practical advice on preventing a recurrence — usually filter cleaning frequency and an annual service.

Frequently Asked Questions
How quickly can you get to me?
Most Brisbane suburbs get a same-day or next-day booking. During December–February heatwaves demand surges, so call early in the day for the best chance of a same-day slot. Emergency after-hours attendance is also available.
Why is my air conditioner running but not cooling?
The most common causes are low refrigerant from a leak, a dirty or blocked filter and coil restricting airflow, a failed capacitor stopping the compressor, a faulty thermistor misreading temperature, or an outdoor fan motor that has stopped. Diagnosis takes a technician about 30–45 minutes.
Why is water dripping from my indoor unit?
Usually a blocked condensate drain — Brisbane’s humidity and airborne dust produce algae and sludge that clog the line. It can also be caused by a frozen coil melting, an incorrectly sloped drain, or a failed condensate pump. It should be fixed promptly because it damages plasterboard and can cause mould.
Should I repair or replace my air conditioner?
As a general rule, replace if the unit is over 10–12 years old, uses phased-out R22 refrigerant, or the repair cost exceeds roughly half the price of a new installed system. Repair if it is under 8 years old and the fault is a discrete component. We give you the numbers on site so you can decide.
Is it just low on gas? Can you top it up?
Air conditioners are sealed systems and do not consume refrigerant. If it is low, there is a leak. Australian law requires leaks to be repaired rather than repeatedly topped up, and a top-up without repair simply means paying again in a few months. We locate and fix the leak first.
What do the error codes mean?
Each brand uses its own codes — for example Daikin U0 indicates low refrigerant, Mitsubishi Electric P8 relates to pipe temperature faults, Fujitsu flashing operation and timer lights encode a fault number. Tell us the code when you book and we can often arrive with the likely part already on the van.
Do you warranty your repairs?
Yes. Parts carry the manufacturer’s warranty and our workmanship is warranted for 12 months. If the same fault recurs within that period, we return at no charge.
Can you work on units still under manufacturer warranty?
Yes, and we’ll advise you when a fault should be claimed through the manufacturer’s warranty agent instead so you’re not paying for something covered.
My unit is tripping the circuit breaker — is that dangerous?
Treat it seriously. It usually indicates a short, a failing compressor drawing excessive current, moisture ingress or a failed component. Leave the isolator off and call us rather than repeatedly resetting the breaker.
