Aircon Installation in Serangoon Garden

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.

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 single split cools one room cheaply. A multi-split runs several indoor heads off one outdoor unit — good for a few rooms without ductwork. Ducted gives even whole-home comfort but costs most and needs ceiling/roof space. Match the choice to how many rooms you actually cool.

In Serangoon Garden, get three quotes from certified installers, check reviews and refrigerant-handling credentials, and confirm the sizing and electrical scope in writing. The cheapest quote often skips the load calc or the dedicated circuit.

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.

Sizing is by room area, ceiling height, insulation, window area and sun exposure — a good installer does a load calculation, not a guess. An undersized unit runs constantly and never cools; an oversized one short-cycles and wastes energy. Insist on a sizing rationale in the quote.

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.
