KL · Aircond not cold

An aircond that runs all night but leaves the bedroom warm is usually dirty, sometimes low on gas, and occasionally broken. Here is how to tell which - and what it costs to fix.

  • Check 5 things first
  • Most cases: dirty coil
  • Diagnosis if unsure

The fixes that solve most cases

A chemical wash fixes the most common cause - a coil clogged with damp dust. Start with a general service if the unit was cleaned recently.

Book online and confirm in the app - no card needed now.

Five quick checks

  1. 1

    Mode

    Is the remote on Cool (snowflake), not Dry, Fan or Auto? Dry mode in particular feels weak.

  2. 2

    Temperature setting

    Set it to 24°C and give it 20 minutes. Setting 16°C doesn't cool faster.

  3. 3

    Filter

    Pull out the filters behind the front panel. If they're grey and furry, rinse them and try again.

  4. 4

    Outdoor unit

    Is its fan spinning? Is it blocked by laundry, plants or a cover? It needs space to release heat.

  5. 5

    Room load

    A 1.0hp unit in a west-facing room with the door open will struggle at 4 pm. See our HP room size guide.

Usual causes

Dirty coil or blower

Air is cold but weak. Fixed by a chemical wash.

Low gas

Air is barely cool, frost on pipes. Needs a leak check and gas top up.

Faulty capacitor

Indoor fan runs, outdoor unit silent. Small part, quick repair.

Wrong size

Unit too small for the room. Common when a 1.0hp is moved to a bigger room.

A general service costs RM89.24, a chemical wash RM147.20, an R32 gas top up RM92.00, and a diagnosis visit RM46.00.
Check the mode, wash the filter and make sure the outdoor fan is running. If it still isn't cold, book a service. We have a full guide in Bahasa Melayu too.
Filters and cover washed, coil and blower cleaned, drain tray and pipe cleared, compressor checked and gas pressure measured.
Mould on the coil is not removed by a general service. A chemical wash is the fix; the technician will advise you.
A general service starts at RM89.24 for one wall-mounted unit, including transport. Servicing more units on the same visit lowers the price per unit.
Every four to six months for units used daily. If you run it all night, every four months keeps it efficient and saves on your TNB bill.
