Real AC cases by district, service type and issue
These project cases show how our technicians handle common air conditioner problems in Hong Kong homes, shops and offices. Each case records the district, unit type, symptoms, inspection process, result and site photos, so you can compare a similar situation before asking for a quotation.
If your AC is leaking, not cooling, noisy, dirty, recently moved, or needs installation at a new location, browse the related case first and then send photos by WhatsApp for a clearer assessment.
When comparing cases, pay attention to the district, indoor and outdoor unit position, pipe distance, access difficulty, fault symptoms and final result. A Kwun Tong shop, Sha Tin home or Tsuen Wan office may need a different repair method even when the symptom looks similar, so the case notes help explain why the quote may vary.
