Aircon Installation in Eunos

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.

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.

A single-zone split unit for one room is the cheapest entry point; a multi-zone system serving several rooms is a mid-range job; a ducted/central system for a whole home is the priciest. The unit's size (in BTU/kW) and the difficulty of the pipe and cable runs drive cost more than the brand.

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.

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.

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.
