Aircon Installation in Melbourne

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.

In Melbourne, 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 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.

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 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.
