Aircon Installation in Singapore
Compare 567 aircon installation contractors in Singapore. Learn what installation involves, what separates a solid job from a rushed one, and how our scoring works.
Aircon installation covers putting in a new system from scratch or replacing an old one, usually a split-unit setup with one or more indoor fan coil units connected to an outdoor compressor. The work includes running copper piping and drainage, mounting brackets, electrical wiring to a dedicated circuit, vacuum-testing the pipework to remove air and moisture, and charging the system with refrigerant. For HDB flats this also means applying for the right permits and following estate guidelines on where the outdoor unit can sit. We track 567 businesses in Singapore doing this work, from small two-man outfits to larger firms handling condo and commercial fit-outs.
A proper installation shows in the details: pipe runs that are insulated and boxed up neatly rather than left exposed, correct pipe sizing for the unit's capacity, a vacuum pump test done and documented (not skipped), and drainage that actually falls to a proper outlet instead of pooling. Ask what brand and model they're quoting, whether the price includes piping length beyond a base allowance, and what warranty covers labour versus parts. Cheap quotes often hide extra charges for piping, trunking, or disposal of the old unit later.
Our scoring looks at how contractors are rated on workmanship, communication, and follow-up service across their job history, not just star counts.

Message on WhatsAppCommon questions about aircon installation
- How much does aircon installation cost in Singapore?
- A single split-unit system typically runs from a few hundred dollars for a basic system-1 setup to well over a thousand for multi-split systems with several indoor units, depending on brand, capacity, and piping distance. Get itemised quotes so you know what's included for piping, brackets, and disposal of any old unit.
- How long does an aircon installation take?
- A single-unit installation in an HDB flat or condo usually takes half a day to a full day. Multi-split systems with several indoor units and longer pipe runs can take one to two days, especially if trunking or false ceiling work is involved.
- How often does an aircon system need to be replaced?
- Most split-unit systems last 10 to 15 years with regular servicing. Signs it's time to replace rather than repair include frequent breakdowns, rising energy bills, or a compressor that's failed and would cost nearly as much to fix as to replace.
- What should I check before hiring an installer?
- Ask for their experience with your specific building type (HDB, condo, or landed), whether they handle the permit paperwork for you, what warranty applies to both the unit and their labour, and whether they do a proper vacuum test before charging refrigerant rather than just a quick pressure check.
