Common issues

What Are the Common Signs Your Perth Air Conditioner Needs Repair?

Most air conditioner problems give warning signs before they become complete failures, especially heading into Perth's intense summer period. If you're experiencing any of these, early diagnosis can prevent a far more costly repair.

Poor Cooling or Heating

The system runs but doesn't reach the set temperature. Often caused by low refrigerant, a dirty coil, or a failing compressor.

Frequent Shutdowns

The system starts then shuts down shortly after. Can indicate electrical faults, refrigerant issues, or a dirty filter causing overheating.

Electrical Faults

Tripping circuit breakers, error codes on the display, or failure to power on. These require an electrician, not just a general service.

Unusual Noises

Rattling, clicking, or grinding sounds during operation. Often caused by loose components, debris in the unit, or a failing fan motor.

Older Systems

Systems over 8-10 years old are more prone to failures and often run inefficiently. A service can identify whether a repair or replacement is more cost-effective.

New Installation Concerns

System not performing as expected after a recent install? We can inspect the work and identify whether installation or commissioning issues are the cause.

Our approach

Why Should Perth Homeowners Service Their Air Conditioner Annually?

We don't replace components based on guesswork. Before any repair is recommended, we systematically test the system, including electrical circuits, refrigerant pressures, airflow, controls, and mechanical components, to identify the actual cause. Perth's long cooling season (often 5–6 months of continuous use), combined with dust, pollen, and coastal salt air in beachside suburbs, means filters and coils degrade faster than in cooler climates.

Annual servicing keeps your system running at peak efficiency and is far less likely to fail on the next 42°C Perth summer day. This diagnostic-first approach means you're not paying to replace parts that don't need replacing, and we can give you an honest comparison between repair and replacement cost. For energy efficiency guidance, check the Australian Energy Rating label (now up to 10 stars under current MEPS/GEMS regulations) when considering whether to repair or replace an older unit. Note: if your existing system uses R22 refrigerant, it may no longer be serviceable from 2025 onwards as R22 stocks for recharging are effectively depleted. See DCCEEW ozone-depleting substance information for details on the R22 phase-out. All refrigerant handling by our team is performed under an ARC refrigerant handling licence.

Some AC faults involve electrical hazards. If your system is tripping breakers or showing error codes, don't ignore it; have it inspected.

Repair or replace?

Should You Repair or Replace Your Perth Air Conditioner?

Not every repair is worth doing. If your system is old, the compressor has failed, or the cost of repair is approaching the cost of a new unit, we'll tell you that clearly, rather than quoting a repair that won't give you long-term value. This is especially relevant for Perth systems over 10 years old that have endured many long, hot summers.

When we carry out a diagnosis, we factor in system age, the cost of the repair, estimated remaining lifespan, and the running efficiency of the existing system compared to a modern replacement. You get a clear recommendation, not just a quote. Ares Energy holds a Refrigeration and Air Conditioning (RAC) licence in Western Australia, ensuring all repair and servicing work meets regulatory requirements.

Common questions

Frequently Asked Questions: AC Service & Repairs Perth

How often should I service my air conditioner in Perth?

Annual servicing is strongly recommended for Perth air conditioners. Perth's long cooling season (often 5–6 months of regular use), combined with dust storms, pollen, and coastal salt air in beachside suburbs, causes filters and coils to clog significantly faster than in cooler climates. A serviced system runs more efficiently, consumes less electricity on those 40°C+ Perth summer days, and is far less likely to break down when you need it most. Homes in coastal areas like Cottesloe, Scarborough, or Fremantle may benefit from bi-annual servicing due to salt air corrosion.

Why is my air conditioner not cooling properly in Perth?

The most common causes of poor cooling in Perth homes include: a clogged air filter or dirty indoor coil (very common given Perth's dusty environment), low refrigerant due to a slow leak, a failing compressor, incorrect system sizing for the space or roof type, or electrical faults with the circuit or control board. During Perth's extreme heat events, even a well-maintained system will struggle if it was undersized for the room's actual heat load. Our technicians test and diagnose systematically before recommending any repair.

What licence is required to service an air conditioner in WA?

In Western Australia, servicing an air conditioner, particularly tasks involving refrigerant handling, recharging, or any electrical work, requires a Refrigeration and Air Conditioning (RAC) licence and/or an electrical licence. Ares Energy holds an ARC (Australian Refrigeration Council) Refrigerant Handling Licence and a RAC licence in Western Australia, plus full electrical contractor licensing, meaning all servicing and repair work is fully compliant with WA regulations.

Should I repair or replace my old Perth air conditioner?

For systems under 8 years old, repair is usually more cost-effective unless a major component like the compressor has failed. For systems over 10 years old, the repair vs replacement decision depends on the cost of the repair relative to the remaining useful life and the running efficiency of the existing system. Modern inverter units are significantly more energy efficient than older systems. Given Perth's long cooling season, the energy savings from a new high star-rated unit can offset replacement costs faster than in cooler climates. Note: if your existing system uses R22 refrigerant, it may no longer be serviceable as R22 stocks for recharging are effectively depleted from 2025. We provide an honest assessment of both options.

Does air conditioning use a lot of electricity in Perth?

Running costs depend heavily on the unit's energy efficiency rating and how well it has been maintained. Modern inverter-type split systems are significantly more efficient than older fixed-speed units, and a dirty filter or low refrigerant charge will cause any system to work harder and use more electricity. Look for a high star rating on the Australian Energy Rating label. Each additional star represents approximately 10% in energy savings. Annual servicing ensures your Perth system is running at the efficiency it was designed for.

What brands of air conditioner do you service and repair in Perth?

We service and repair all major air conditioning brands across Perth, including Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Fujitsu, Samsung, Panasonic, LG, and more. Our technicians are trained to work across all system types, including split systems, multi-head systems, and ducted air conditioning, regardless of brand or age.

What does an annual AC service include in Perth?

A standard annual service includes filter cleaning and inspection, indoor and outdoor coil cleaning, electrical connection check, refrigerant level check, drain line flush and test, and a system performance test in both cooling and heating modes. For Perth properties near the coast, we also check for signs of salt-air corrosion on the outdoor unit. A service report is provided after each visit, which is useful for warranty claims and maintenance records.
