When Your System Fails, You Need a Fast, Accurate Diagnosis
Your air conditioner has stopped doing its job — it's not cooling, not heating, not blowing air at all, or it's making a noise you've never heard before. Ken Hall's licensed technicians repair all types of air conditioning systems across Adelaide, with same-day response in most cases.
A repair job lives or dies on getting the diagnosis right the first time. Our technicians carry diagnostic equipment and a stocked van to identify and fix most faults in a single visit.
What's Included
Every fault, every system type
- System not heating or cooling — thermostat, refrigerant, compressor and component faults
- No airflow at all — blocked filters, failed fan motors, or ducting obstructions
- Error codes — properly diagnosed, not just cleared and hoped away
- Unusual noises — rattling, buzzing, grinding or hissing
- Refrigerant leaks — detection, repair, and correct re-gassing
- Electrical faults — wiring, control board and sensor issues
- Water leaks — condensate drainage problems, particularly common with split systems
Our Process
You Describe the Problem
Tell us what's happening — this helps us prepare and prioritise urgent cases.
We Diagnose On-Site
A licensed technician identifies the fault and explains it in plain terms.
You Get an Upfront Price
You'll know the cost before any work starts. No surprises.
We Fix It Properly
Quality parts and correct technique, not a quick patch.
Common Faults We Fix, By System Type
Split Systems
Cooling/heating faults, water leaks from a blocked condensate drain, and error codes.
Ducted Reverse Cycle
Uneven airflow (ducting/zoning) or a system unresponsive to the thermostat.
Evaporative Cooling
Worn or scaled pads, a failing water pump, or uneven distribution via ducting.
Multi-Head Systems
A fault on one indoor head usually isolates to that unit, not the shared outdoor compressor.
Signs You Need a Repair vs a Full Replacement
Not every fault is worth fixing on a system that's genuinely near the end of its life. As a rough guide: if your system is under 10 years old, has had few or no previous issues, and the repair cost is a small fraction of a new system's cost, a repair is almost always the right call.
If it's older, has needed repeated repairs, or the repair quote starts approaching a meaningful chunk of a replacement cost, it's worth a second conversation. We'll tell you honestly which situation you're in — see Air Conditioning Upgrades if that's the direction it points.
