Aircon Installation in Yishun
What aircon installation involves
Installing an aircon in a Yishun flat means more than hanging a unit on the wall. The contractor mounts the indoor fan coil and outdoor compressor, runs refrigerant piping and drain lines, sets up electrical connections, then tests for leaks and cooling. Most HDB homes use a system with one compressor feeding several rooms, so planning pipe routes and compressor ledge placement matters.
What to look for
- A written quote that lists the brand, model, piping length, and any extras such as bracket, trunking, or drainage work.
- Clear pricing for extra piping beyond the standard allowance.
- Warranty terms for both the equipment and the workmanship.
- A site visit before quoting, especially for multi-room systems.
- Proper vacuuming and pressure testing of the piping, not just a quick connection.

Common questions about aircon installation
- How much does aircon installation cost in Singapore?
- For a typical HDB flat, a single-split unit installation often runs a few hundred dollars if bought separately, while a system 3 or 4 with equipment commonly costs from about 2,500 to 5,000 dollars or more depending on brand and tonnage. Extra piping, bracket work, and electrical changes add to this. Always get an itemised quote.
- How long does installation take?
- A single unit usually takes a few hours. A multi-room system in a flat typically takes half a day to a full day, depending on pipe routing and any trunking or hacking needed.
- How can I tell if an installation was done well?
- Check that the unit is level, the drain flows freely with no dripping, the piping is neatly covered, and each room cools properly with no unusual noise or vibration. Ask for the warranty in writing and keep your receipt.
- How often does an aircon need to be installed?
- Installation is one-off, but units usually last about 10 to 15 years with regular servicing. You would reinstall when replacing the system or moving it during renovation.
