What licence should an aircon servicing company have?

  • BCA Trained Air-conditioning Unit Installer

    Building and Construction Authority (BCA) · Required by law

    Only a BCA-trained installer with an identification pass may install or replace an air-conditioner condensing unit on the exterior of a building. For HDB flats the installer submits Form AC-02 to the HDB branch within 14 days of installation.

    Check the official register

  • Licensed Electrical Worker (for new power points or isolators)

    Energy Market Authority (EMA) · Required by law

    Adding or modifying wiring, such as a new aircon power point or isolator, must be done by an EMA-licensed electrical worker. Routine servicing does not need one.

How to choose a aircon servicing company

  • Match the service to the problem: general servicing for routine cleaning every few months, a chemical wash for weak cooling or smells, a chemical overhaul for heavy dirt, mould or water leaking from the indoor unit.
  • Ask for prices by BTU size and unit type. A 24k BTU or ceiling cassette unit costs noticeably more than the headline rate.
  • If you need a gas top-up, ask the technician to check for a leak and to show pressure readings. Repeated top-ups without fixing the leak waste money.
  • For new installations or replaced outdoor units, insist on a BCA-trained installer and, for HDB flats, confirm they will submit Form AC-02.
  • Compare annual contracts carefully: they lower the per-unit price but lock in the number of visits, so check what happens if you cancel.

Red flags

  • Very low headline price followed by on-site upselling to a chemical overhaul without showing you the dirt or fault.
  • Gas top-up recommended at every visit, which suggests an unrepaired leak.
  • Installers who cannot show a BCA trained-installer pass but offer to mount an outdoor unit or bracket.
  • Quotes that exclude GST, transport or 'difficult access' charges until the job is done.

Questions to ask before you book

  • What exactly is included in general servicing: filters, coil, blower, drain pipe flushing, outdoor unit?
  • What is the price for my specific units (brand, BTU, wall-mounted or cassette)?
  • If gas is low, will you leak-test before topping up, and what refrigerant does my unit use?
  • Is there a workmanship warranty after a chemical wash or overhaul?
  • Will you check the outdoor unit bracket for corrosion?

Questions about aircon servicing in Singapore

How much does aircon servicing cost in Singapore?

General servicing of a wall-mounted unit typically costs about $20–$50 per unit in 2026, with most companies requiring at least two units per visit. Ceiling cassette units start around $70–$100 per unit. Chemical washes are around $80–$100 per wall-mounted unit and chemical overhauls about $110–$250. Contracts with several visits a year bring the per-unit price down.

What is the difference between a chemical wash and a chemical overhaul?

A chemical wash cleans the coil and blower with chemicals while the indoor unit stays on the wall. A chemical overhaul goes further: the fan coil unit is taken down, dismantled and soaked, which removes heavy grime and mould. Overhauls cost roughly double a wash and suit units that leak water, smell or cool poorly despite regular servicing.

How much is an aircon gas top-up in Singapore?

Expect roughly $80–$150 per unit in 2026, depending on the refrigerant (R22, R410A or R32) and the provider. Refrigerant does not get used up in normal operation, so needing gas usually means there is a leak. Ask the technician to locate and repair the leak, otherwise you will pay for top-ups repeatedly.

Who can install an aircon outdoor unit in an HDB flat?

Only a BCA-trained air-conditioning unit installer may install or replace an outdoor condensing unit on the building exterior. For HDB flats, the installer must submit Form AC-02 to your HDB branch within 14 days. Flat owners can face a fine of up to $5,000 and/or six months' jail for improper installation, and up to $20,000 and/or a year's jail if a poorly maintained unit or bracket falls.

How often should I check my aircon bracket?

BCA advises checking the outdoor unit's supports for corrosion at least once every six months, which you can do during servicing. If a bracket is badly corroded, engage a BCA-trained installer to replace it, preferably with stainless steel. Homeowners are responsible for maintaining the supports of their aircon units.
