New AC Installation in Perth metropolitan
New AC installation covers fitting a cooling (or reverse cycle heating and cooling) system into a home or business that either has no existing setup or needs a full replacement rather than a repair. In Perth this usually means split systems for individual rooms, multi-head splits for several zones off one outdoor unit, or ducted reverse cycle systems that condition the whole house through ceiling ductwork. The job includes sizing the system to the space, running refrigerant lines and drainage, mounting the outdoor condenser, wiring to a dedicated circuit, and commissioning the unit so it runs at the rated capacity.
With 290 businesses listed in this category, the gap between a good job and a poor one usually comes down to correct sizing (not just "biggest unit that fits the budget"), tidy pipe and cable work, proper refrigerant charging verified with gauges, and whether the contractor pulls the right permits and safety switches. Ask for a load calculation rather than a rough guess based on room area alone, and get the brand, model, and star rating in writing before work starts.
Our scoring weighs licensing, customer feedback, response times, and consistency across jobs rather than just star averages. You can see how that works on the methodology page, and compare top-rated contractors across all AC services on the ranked guide.

Common questions about new ac installation
- How much does a new AC installation cost in Perth?
- A single split system install typically runs from around $1,800 to $3,500 depending on brand and capacity, while a full ducted reverse cycle system for an average home can range from roughly $8,000 to $16,000 or more depending on zoning and ductwork complexity. Get at least two or three quotes since pricing varies a lot based on system size and how much electrical or roof work is needed.
- How long does a new AC system last before it needs replacing?
- Most split and ducted reverse cycle systems in Perth's climate last 12 to 18 years with regular servicing. Units running hard through long, hot summers with little maintenance tend to wear out sooner, especially the outdoor compressor.
- What should I expect on installation day?
- Expect a site check first (if not already done at quoting stage), then mounting the indoor unit, running the outdoor unit, connecting refrigerant lines and drainage, electrical hookup, and a final test where the installer checks pressures and airflow. A straightforward single split usually takes half a day; ducted systems can take one to three days depending on ceiling access and zoning.
- How do I judge whether an installer did a quality job?
- Check that the outdoor unit sits level on proper brackets or a pad, refrigerant lines are insulated and clipped neatly, there's a condensate drain that actually slopes away from the wall, and you get a compliance certificate for the electrical work. A good installer will also show you the commissioning readings, not just switch it on and leave.
