Car Aircon Repair Case Studies
Real aircon jobs from our Sin Ming workshop. In Singapore heat an aircon fault never stays small, and these cases show how we trace each one to the actual cause, from a seized compressor to an evaporator coil replaced behind the dashboard, rather than just topping up gas.
Each case records the symptom, the diagnosis, the parts replaced and, where recorded, the cost. Aircon repairs carry a warranty of at least 6 months. WhatsApp us what the aircon is doing and we will tell you what it likely needs and quote before any work begins.
6 documented aircon jobs on this page, 3 with costs recorded. Every case states exactly what its figure covered, and your car is always quoted after diagnosis.
Symptoms worth checking
- Aircon blowing warm, or cold fading after a short drive
- Cold that keeps failing again after previous repairs
- Hissing, clicking or a burning smell when the aircon runs
- A squealing belt when the compressor engages
- Water or a musty smell inside the cabin
