Aircon Installation in Singapore
Compare 396 aircon installation contractors in Singapore. Learn what installation involves, what to check before hiring, and how our scoring ranks them.
What aircon installation involves
Installation covers more than hanging a unit on the wall. A proper job includes surveying the flat, mounting the indoor fan coil and outdoor condenser, running copper piping, drainage and wiring, then vacuuming the lines, testing for leaks and commissioning the system. In HDB flats and condominiums, condenser placement on the ledge or rack also has to follow town council or management rules.
What to look for
- A written quote that lists the brand, model, number of ticks, piping length and any extras such as trunking, bracket or electrical work.
- Clear warranty terms, covering both the equipment and the workmanship.
- Experience with your property type, whether a BTO, resale flat, condo or landed home.
- Sensible advice on system type (single split or multi-split) and sizing, not just the most expensive option.

Message on WhatsAppCommon questions about aircon installation
- How much does aircon installation cost in Singapore?
- For a standard split system, installation labour and basic piping commonly run from about S$150 to S$400 per unit, on top of the unit price. A multi-split system for a whole flat, with the units included, often falls between S$2,500 and S$6,000 or more depending on brand and number of rooms. Extra piping, trunking, bracket and electrical work add to this. Always compare itemised quotes.
- How long does installation take?
- A single unit usually takes 2 to 4 hours. A multi-split setup for a 3 to 4 room flat typically takes half a day to a full day, depending on piping routes and access to the condenser ledge.
- What should I expect on installation day?
- The installer checks the mounting points, fits the indoor and outdoor units, connects piping, drain and power, vacuums the lines and tests cooling and drainage. Ask them to show the unit running and to confirm the drain flows properly before they leave.
- How can I tell if an installer is good?
- Look for itemised quotes, written warranty on workmanship, consistent recent reviews that mention clean work and follow-up, and willingness to explain sizing. Be cautious of quotes far below others or ones that avoid listing piping length and materials.
