"The cost to repair an AC in Hong Kong varies by the problem, but basic repairs can range from approximately HKD $500 to $1,000, while major repairs like a compressor or refrigerant leak can cost HKD $1,500 to $4,000 or more. Inspection fees are often around HKD $500, with the repair costs and any needed parts being quoted separately. "
