Why it matters

Why Does Correct AC Installation Matter for Perth Homes?

Perth's hot, dry summers, regularly exceeding 40°C in January and February, place extreme demand on air conditioning systems. Homes with terracotta tile or metal roofs retain heat well beyond outdoor temperatures, making correct system sizing and electrical installation critical to performance and longevity.

Many air conditioning problems are not caused by the unit itself, but by how it has been installed or connected electrically. Ares Energy holds a Refrigeration and Air Conditioning (RAC) licence and an Australian Refrigeration Council (ARC) Refrigerant Handling Licence in Western Australia, ensuring every installation meets the legal and technical requirements for Perth properties. New split systems now commonly use R32 refrigerant, which has replaced the older R410A due to its lower global warming potential. R22 refrigerant is now banned in Australia, and from 2025 stocks for recharging R22 systems are effectively depleted. Under GEMS (Greenhouse and Energy Minimum Standards) regulations, all new air conditioners must meet MEPS (Minimum Energy Performance Standards). Look for a high star rating on the Australian Energy Rating label (now up to 10 stars) to minimise electricity bills across Perth's long cooling season.

Most AC failures trace back to incorrect electrical installation, not the unit itself.

Common questions

Frequently Asked Questions: Air Conditioning Perth

What size air conditioner do I need for my Perth home?

As a general guide, Perth homes require approximately 0.06–0.07 kW per square metre for standard rooms. However Perth's hot climate, roof type (terracotta tiles and metal roofs retain significant heat), ceiling height, insulation quality, and window orientation all affect the correct size. An undersized unit will run continuously without reaching temperature, while an oversized unit short-cycles and increases wear. Our technicians carry out a proper heat load assessment before recommending any system.

Should I choose a split system or ducted air conditioning for my Perth home?

Split systems are ideal for cooling or heating individual rooms or open-plan living areas, and are the most cost-effective solution for most Perth homes. Ducted systems suit larger homes where whole-home climate control is needed, typically 4+ bedrooms, but cost significantly more ($8,000–$20,000+ installed). For Perth's Mediterranean climate, a reverse cycle split system provides excellent year-round performance: cooling in our hot summers and heating on mild winter mornings. We assess your home and recommend the right system without upselling.

What licence does an air conditioning installer need in WA?

In Western Australia, anyone installing, servicing, or handling refrigerant in an air conditioning system must hold a Refrigeration and Air Conditioning (RAC) licence issued under the Electricians Act 1946 (WA). Additionally, an expert electrician must connect the unit to the electrical supply. Ares Energy holds both the RAC licence and full electrical contractor licensing in WA, so your installation is fully legal, safe, and compliant with Australian Standards.

How often should Perth homeowners service their air conditioner?

Annual servicing is strongly recommended for Perth air conditioners. Perth's long cooling season (often 5–6 months of regular use), combined with dust, pollen, and coastal salt air in beachside suburbs, causes filters and coils to clog faster than in cooler climates. A serviced system runs more efficiently, consumes less electricity, and is far less likely to fail on a 42°C Perth summer day. Homes near the coast should consider corrosion-resistant models and may benefit from bi-annual servicing.

How much does air conditioning installation cost in Perth?

A fully installed split system air conditioner in Perth typically costs between $1,800 and $4,800, including supply and installation of the unit, refrigerant lines, electrical connection, and commissioning. The final cost depends on the system size (kW capacity), brand selected (Daikin, Mitsubishi Electric, Fujitsu, Samsung, Panasonic), installation complexity, and whether electrical upgrades are required. Ducted systems for larger Perth homes range from $8,000 to $20,000+. Contact us for a no-obligation quote specific to your property.

Is reverse cycle air conditioning worth it in Perth?

Yes. Reverse cycle air conditioning is the most practical and energy-efficient choice for Perth homes. Perth's Mediterranean climate delivers hot, dry summers and mild winters, meaning a reverse cycle system provides both summer cooling and winter heating from a single unit. Modern inverter-type reverse cycle units are highly energy efficient. Look for a high star rating on the Australian Energy Rating label (now up to 10 stars) to minimise your electricity bills across Perth's long operating season.

Why is my air conditioner not cooling properly in Perth?

Common causes of poor cooling include: a clogged filter or dirty coil (very common in Perth's dusty environment), low refrigerant charge due to a leak, a failing compressor, an undersized unit for the space, or electrical issues with the circuit or control board. During extreme Perth heat events, even a well-maintained system may struggle if it was not correctly sized for the heat load. Our technicians diagnose the root cause before recommending any repair, so you only pay for what's actually needed.
