Aircon Servicing & Repair in Singapore
A guide to choosing an aircon servicing and repair company in Singapore, with 272 providers compared and what actually matters when hiring one.
Singapore's climate means air conditioners run almost year round, and that constant use is exactly why servicing and repair is its own trade rather than an afterthought. This category covers general servicing (chemical wash, coil cleaning, gas top-up), fault diagnosis and repair (leaking water, poor cooling, error codes, noisy compressors), and the smaller jobs in between like re-gassing or replacing a capacitor. We list 272 businesses in Singapore that do this work, from one-man technicians covering a few HDB towns to larger outfits that handle condo management contracts and commercial chiller systems.
What to look for before you book
Not every technician is equally comfortable with every job. A company that's fast and cheap for a basic gas top-up on a wall-mounted unit may not be the right call for a multi-split system fault or a ducted aircon that needs isolation and pressure testing. Check whether they quote a flat fee upfront or only after inspection, whether the quote separates labour from parts (compressor, PCB, capacitor), and whether they give any warranty on the repair itself, not just on parts. Also worth asking: do they bring their own chemical wash equipment and vacuum pump, or do they subcontract more technical jobs out.
How we score providers
Our ranking weighs how a business is reviewed over time, how it responds to complaints, and signals like licensing and how long it's been operating, rather than just a star average at a single point in time. The full method is explained on our methodology page. For a shortlist of providers that score well on these measures, see our ranked guide to aircon servicing and repair in Singapore.

Common questions about aircon servicing & repair
- How much does aircon servicing cost in Singapore?
- A basic service (cleaning filters, checking gas pressure, general inspection) for a single wall-mounted unit typically runs from around $20 to $40 per unit, with most companies offering discounted rates for multiple units serviced in the same visit. A full chemical wash, which involves dismantling the unit to clean the coil and blower, usually costs more, often $60 to $120 per unit depending on the type and how dirty it is. Repairs involving parts like a compressor or PCB can run into hundreds of dollars, so it's worth getting the diagnosis and quote before agreeing to work.
- How often should aircon units be serviced?
- For units in regular household use, a general service every 3 months and a full chemical wash every 6 to 12 months is a common rule of thumb in Singapore's climate. Units that run almost continuously, such as in home offices or for households sensitive to dust, may need chemical washes more often, closer to every 6 months, to avoid mould smell and reduced cooling.
- What should I expect during a typical service visit?
- A technician should check and clean the filter, inspect the drainage for clogs or leaks, check refrigerant gas pressure, and clean the outdoor condenser unit if accessible. For a chemical wash, expect the indoor unit's cover and coil to be removed, cleaned with a chemical solution and water, and reassembled, which usually takes 30 to 60 minutes per unit. A good technician will also flag early signs of wear, like a weakening capacitor or a coil starting to corrode, rather than just doing the minimum requested.
- How can I tell if a repair job was done properly?
- Cooling should feel noticeably stronger within minutes of switching the unit back on, and there shouldn't be any dripping, unusual noise, or smell afterward. For gas top-ups or leak repairs, ask what pressure they charged the system to and whether they tested for leaks before closing up, since a rushed job often means the same fault returns within weeks.
