Air Conditioning Installation Perth: Complete 2026 Guide

Choosing the right air conditioning system in Perth isn’t just about cooling a house. It’s about energy efficiency, long-term costs and how well it’ll perform in Perth’s extreme summer heat and wet winters.

We’ll explain the air conditioning installation process, outline system types, realistic costs and installation timeframes, as well as help you decide which option will suit your specific needs best.

What Types of Air Conditioning Can You Install in Perth?

Perth homes can vary dramatically in size, age and construction style, so there won’t be a one-size-fits-all air conditioning solution that suits every property. Mouritz installs split systems, ducted units and evaporative across Perth, beach designed to meet different cooling needs, budgets and layouts.

Split System Installation Perth

Split systems are generally one of the most common options in Perth homes. They consist of an indoor wall mounted unit and an outdoor condenser, making them the perfect choice to cool individual rooms or specific living areas. Split systems are also popular thanks to their lower up-front cost, quick installation times and impressive energy efficiency (when properly sized).

Mouritz installs split systems with a specific focus on airflow positioning, accurate load calculations and long-term performance. Keeping these in mind during installation allows the system to cool efficiently without excessive power use, which will directly translate into ongoing costs.

Ducted Air Conditioning Installation Perth

Ducted air conditioning provides house-wide temperature control via a concealed network of ducts installed in your ceiling or roof space. This system allows you to cool or heat multiple rooms from a single unit, with zoning options that let you control airflow to various pre-set areas of the home.

It’s especially suited to larger homes or households looking for a clean, unobtrusive air conditioning solution. Mouritz designs ducted systems to suit your home layout, ceiling access and insulation to ensure consistent temperatures.

Evaporative Air Conditioning Installation Perth

Evaporative air conditioners work by drawing outside air through water soaked filter pads before circulating that cool air throughout the home. This system is particularly effective in Perth’s dry climate, where lower humidity levels allow evaporative cooling to perform effectively.

Mouritz installs evaporative air conditioning systems that provide constant air circulation, lower running costs and a natural cooling feel. These systems are best suited to properties with adequate ventilation and are often chosen by homeowners who prioritise energy efficiency and a lower power bill.

How Much Does Air Conditioning Installation Cost in Perth?

Air conditioning installation costs in Perth will vary depending on the system type, property layout, access requirements and any necessary electrical upgrades.

Split System Installation Costs

Split system installation is generally the most affordable option for Perth homes. Costs will depend on unit capacity, installation complexity and the distance between the indoor and outdoor components. Because split systems cool individual rooms and spaces, they’re often the most cost effective solution for bedrooms, home offices and living rooms.

A more straightforward installation also means they’re a solid choice for homeowners looking for reliable cooling without the greater investment of whole-home systems.

Ducted System Installation Costs

Ducted air conditioning costs are higher due to the sheer scale of the system and labour involved. Installation includes duct design, ceiling or roof access, zoning setup and system commissioning. While upfront investment in a ducted system is greater, the unit provides long-term comfort, increased property values and full temperature control over the home.

Ducted systems should be specifically designed and planned with efficiency in mind to help reduce ongoing energy consumption and to prevent common challenges like uneven cooling or unequal zones.

Evaporative System Installation Costs

Evaporative air conditioning typically costs less than ducted reverse cycle systems and can be very economical to run, especially in Perth’s climate. Final costs and pricing will depend on a multitude of factors, including unit size, ducting requirements and roof structure.
Because evaporative systems utilise water as opposed to refrigerant to cool the air, they tend to consume much less electricity, which can significantly reduce operational costs during peak summer months.

How Long Does Air Conditioning Installation Take in Perth?

Installation timeframes will depend on the particular unit and system type you’ve chosen as well as property access and ease of operations, but clever scheduling and minimal disruptions should be prioritised.

Split System Installation Timeframe

Split system air conditioners are generally the quickest to get up and running thanks to their self-contained design. In many homes, installation can often be completed within a single visit, assuming that access is straightforward and no additional electrical or structural work is required.

Other factors like wall construction, distance between indoor and outdoor units and switchboard capacity can affect how long the installation takes. Correct placement and commissioning is essential for the system to operate efficiently from the outset.

Ducted System Installation Timeframe

Ducted air conditioning installations necessitate more planning and on-site work than a split system will. Installation timeframes will vary depending on home size, roof space access, number of zones and whether it’s a new property or existing building.

Because ducted systems involve ductwork design, ceiling work and airflow balancing, installation may take place over multiple stages. This work should be scheduled carefully to ensure compliance and long-term reliability rather than rushing the process.

Evaporative System Installation Timeframe

Evaporative air conditioning installation timeframes vary based on roof access, ducting layout and water connection requirements. In most cases, installation is carried out over multiple visits that’ll depend on system size and home configuration.

Correct installation is critical to ensuring even airflow, cooling and effective operation in Perth conditions. Technicians must take the time required to set up the system correctly. Installation time will ultimately be determined by system requirements and site conditions.

What’s the Best Air Conditioning for Perth’s Climate?

Understanding Perth’s Unique Climate

Perth typically experiences long periods of dry, high summer heat with cooler winters. This climate makes energy efficiency and airflow design critical when choosing an air conditioning system. Systems that are improperly sized or installed poorly will most likely struggle during heatwaves and consume excessive amounts of power.

Which System Works Best in Perth?

Evaporative air conditioning is known for performing exceptionally well during hot, dry weather and offers lower ongoing running costs. Reverse cycle air conditioning, including split and ducted systems, offer both cooling and heating, making them versatile year round options.

The best system for you will be determined by how you use your home, the number and size of the rooms you want to cool and, of course, your budget. All these factors should be taken into account before a system is selected, balancing comfort, efficiency and long-term value.

Do You Need Service & Maintenance After Installation?

Regular servicing is crucial to maintaining system efficacy, reliability and air quality. Filters, electrical components and airflow performance all require periodic checks and servicing. Ongoing maintenance also helps reduce power consumption and prevents costly breakdowns or faults.

Professional servicing for split, ducted and evaporative systems, helps homeowners protect their investment and continue to maintain consistent comfort in their home.

Frequently Asked Questions: FAQs

Can you install air conditioning in an old Perth home?

Yes. Older homes can accommodate split systems, ducted systems or evaporative cooling depending on roof access, structural layout and space for ducting. A site assessment is recommended to determine the best approach while ensuring efficient operation and compliance with relevant standards.

What’s the best time to install air conditioning in Perth?

Spring and early winter are generally ideal for installation, ahead of peak summer temperatures. Installations can also be carried out year-round, but planning ahead helps ensure availability of installers and reduces delays during hotter periods when demand is highest.

Do I need council approval for AC installation in Perth?

Most residential installations do not require council approval. Exceptions include heritage-listed properties, strata-managed buildings or properties with specific planning overlays. It’s important to check with the local council before installation to confirm whether any approvals or conditions apply. 

How do I choose between evaporative and refrigerated?

Evaporative systems are well-suited to Perth’s dry climate and offer lower running costs, but they don’t provide any heating. Refrigerated reverse cycle systems deliver both heating and cooling with precise temperature control year round. The best choice will depend on comfort preferences, budget and the layout of the house. 

Can you install multiple split systems vs ducted?

Yes. Multiple split systems can be used to cool individual rooms independent of one another, while ducted systems provide whole-home control from the one unit. Considerations include installation complexity, upfront cost, running costs and long-term efficiency when deciding between these options. 

What rebates are available in Perth for AC installation?

Eligible households in Western Australia can access support through the Energy Concession Extension Scheme and Air Conditioning Rebate, which helps with the cost of operating an air conditioner on an ongoing basis. Subsidy amounts vary depending on location and eligibility, generally tied to concession card status and residence in designated high-heat areas.
