Aircon Installation in Tampines Estate

Handling refrigerant is regulated almost everywhere — installers need the relevant certification (see country notes) and often a separate electrical licence for the power supply. Uncertified refrigerant work is both illegal and a common cause of leaks and voided warranties.

Not always. A new unit often needs a dedicated circuit and isolator, which may require a licensed electrician. Confirm whether the quote includes the electrical supply, or whether that's a separate cost you'll arrange yourself.

A back-to-back single split is often a half-day job; a multi-split takes one to two days; ducted installs run two to four days depending on the ductwork. Long pipe runs, wall chasing and crane access for outdoor units add time.

Clean or replace filters regularly, and have the system serviced roughly annually — coil clean, gas-pressure check and drainage clear. Skipping maintenance cuts efficiency, breeds mould in the drain, and shortens compressor life. Ask about a service plan at install.

Expect a manufacturer warranty on the unit (often 5+ years on the compressor if registered) plus an installer's workmanship warranty on the labour and pipework. Poor installation is the main cause of early failures, so the labour warranty matters as much as the unit's.

It's sold by 'System' number — System 1 (one unit), System 3 (three indoor units off one compressor), and so on. Match the system to the number of rooms cooled; a typical 3-bedroom HDB flat commonly uses a System 3 or 4.
