Quick Answers
Most Common Aircond Questions
My aircond is running but not cold. What should I do?
The most likely causes are low refrigerant gas, a dirty evaporator coil, or a failing capacitor. WhatsApp KL Renovator at +60182983573 with your unit HP and area — a technician will diagnose and quote before starting.
My aircond is dripping water. Is it dangerous?
Water dripping from the indoor unit is caused by a blocked drain pipe or dirty drain pan. It is not immediately dangerous but should be fixed promptly — prolonged leaking causes mould growth and potential ceiling/electrical damage.
My aircond smells bad when it turns on. What causes it?
Bad smell is caused by mould and bacteria on the evaporator coil. A chemical wash (from RM 120) kills the mould and eliminates the smell permanently. If the smell is like burning, switch off the unit and call immediately.
My aircond light is blinking and it stopped working. What is the error?
Blinking lights are error codes from the PCB. The pattern of blinks indicates a specific fault — low gas, dirty sensor, communication error, or PCB failure. KL Renovator reads the error code and diagnoses the root cause.
Why is my electricity bill high after using the aircond?
A dirty aircond coil or low refrigerant forces the compressor to work harder, consuming more electricity. A chemical wash or gas top-up can significantly reduce running costs.
