Aircon Installation in Victoria

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.

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.

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.

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.

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.

A single split runs about $1,500-5,000 installed; multi-head systems $5,000-14,000; ducted whole-home from around $9,000. Long pipe runs, second-storey installs and three-phase power push prices up.
