Key takeaways

• A multi-split System 3–4 installation runs S$2,300–S$6,500 including piping and trunking.
• Installation quality decides your system's lifespan — bad piping or a sloppy vacuum job shortens it by years.
• Confirm the quote includes piping, trunking and disposal of the old system — cheap quotes hide gaps there.
• Pick installers experienced with your brand and BTU sizing — see our BTU guide.

An aircon system is a S$3,000–S$6,000 purchase that lives or dies on installation quality. Here's what installation should cost, what a proper quote includes, and how to choose the right installer. Full pricing in our aircon cost guide.

If you are looking for aircon installation, be sure to read up on the guidelines set by HDB. Some of the essential pointers include:

• aircon must be installed by a BCA-trained aircon installer,
• email HDB Branch managing your flat within 14 days after installation
• aircon pipings must be run internally
• aircon units cannot be located along corridors.

How to choose well

1. Licensing first. Installers should hold the relevant BCA workhead and be experienced with your brand and BTU sizing.
2. Ask whether piping, trunking, and disposal of the old system are included — that's where cheap quotes hide their gaps.
3. Reviews with specifics beat star counts. Look for reviews that mention your job type and how problems were handled — not just "good service".
4. Itemised quotes only. A lump-sum quote is where surprises hide. Line items let you compare fairly across companies.
5. Never pay fully upfront. Deposit, progressive payments, and a retention until the work is done and checked.
