Air Conditioning Repairs & Fault Finding
Not cooling, dripping water, flashing an error code or making a noise it did not used to make — diagnosed properly before anything gets replaced.
The most expensive thing in air conditioning repair is guessing. Swapping parts until the symptom goes away costs you for every part that was not the problem. So the first thing is a real diagnosis: gas pressures, electrical readings, the error code the board is actually reporting, and what the system is doing rather than what it is supposed to be doing.
Then you get told what is wrong and what it will cost before any work goes ahead. Sometimes that conversation ends with me telling you the unit is not worth repairing — a fifteen-year-old system with a failed compressor is usually a replacement, not a repair, and you are better off hearing that than paying to find out.
Common ones: a system that cools poorly and has lost gas, which means there is a leak that needs finding rather than just a top-up; a unit dripping water inside, which is nearly always a blocked drain; and a system that starts and stops, which is usually electrical or a sensor rather than the compressor everyone fears.
What's included
- Fault finding and diagnostics — the reading, not the guess
- Refrigerant leak detection and repair (a top-up alone is not a fix)
- Water leaks and blocked condensate drains
- Error codes, PCB and control board faults
- Compressor, fan motor and capacitor failures
- Thermostat and sensor replacement
Common questions
My air conditioner is not cooling. What is wrong with it?
The three usual causes are a refrigerant leak, a filthy filter or coil choking the airflow, and an electrical fault stopping the compressor running. They present similarly and need different fixes, which is why diagnosis comes before quoting.
My unit is leaking water inside. Is that serious?
It is almost always a blocked condensate drain, which is a cheap fix and worth doing quickly — the water has to go somewhere and it is usually your ceiling. Turn the unit off until it is looked at.
Can you just top up the gas?
A sealed system does not consume refrigerant. If it is low, it has leaked, and it will leak again. I will find and fix the leak rather than sell you the same top-up every summer — that is not legal practice under ARCTick and it is not honest either.
Is it worth repairing or should I replace it?
Rough rule: if the repair is approaching half the cost of a new system and the unit is over ten years old, replacement usually wins. You will get a straight answer either way, including when the answer costs me the repair job.
