A split system air conditioner that's properly maintained can run efficiently for well over a decade. One that's neglected will lose efficiency, cost more to run, and eventually break down — usually at the worst possible time, like the middle of a Perth heatwave. Whether your system needs a routine service, isn't cooling or heating like it used to, or has stopped working altogether, we provide fast, honest servicing, maintenance, and repairs for split system air conditioners across Perth.
We work on split systems regardless of who installed them, and our approach is always the same: diagnose the actual issue, explain it clearly, and recommend a repair before jumping to replacement.
Air conditioners are working hardest exactly when Perth's weather is at its most extreme, so it pays to have them serviced before the peak of summer rather than after something's already gone wrong. Regular servicing delivers a few clear benefits:
Dust and grime build-up on filters, coils, and fans forces the system to work harder to achieve the same cooling or heating output, which shows up directly on your power bill.
Filters and coils can accumulate dust, allergens, and even mould over time. This is particularly relevant for households with allergy sufferers, young children, or anyone with respiratory sensitivities.
Most major faults don't appear out of nowhere — they're usually preceded by warning signs a technician would catch during a routine service, like a refrigerant leak, a failing capacitor, or a blocked drain line.
Systems that are serviced regularly tend to last considerably longer than those that are only looked at when something breaks.
Some manufacturer warranties require evidence of regular professional servicing to remain valid, particularly for commercial-grade units.
A standard service typically includes:
We recommend most residential split systems be serviced at least once a year, ideally before summer. Systems in commercial environments, or in coastal areas where salt air accelerates corrosion, often benefit from more frequent servicing.
When a split system isn’t working properly, guessing at the cause usually ends up costing more than it needed to. Our technicians diagnose the actual fault first, then talk you through the repair options and costs before doing any work. Common issues we repair include:
Often caused by low refrigerant (indicating a leak), a dirty filter or coil restricting airflow, or a failing compressor.
Usually the result of a blocked or disconnected condensate drain line, though it can also indicate low refrigerant causing the coil to freeze and then thaw.
Can range from a simple tripped circuit or remote control issue through to a failed capacitor, PCB fault, or wiring problem.
Rattling, buzzing, or grinding noises often point to loose panels, a failing fan motor, or debris caught in the outdoor unit.
Musty smells are typically a sign of mould or bacterial growth in the coil or drain pan, which a thorough clean usually resolves.
Most modern split systems display fault codes that point to a specific issue; we can interpret these for most major brands and diagnose accordingly.
Can indicate an incorrectly sized system, a refrigerant issue, or a thermostat/sensor fault.
Usually caused by a blocked filter, dirty blower wheel, or in some cases a failing fan motor.
It’s worth booking a service or inspection if you notice any of the following:
Catching these early is usually the difference between a straightforward, inexpensive repair and a much bigger bill down the track — or a full system replacement.
Not every issue means you need a new system, and we’re not in the business of recommending replacement just because it’s the bigger job. As a general guide, older systems (typically past 10-12 years old) with a significant fault — like a failed compressor — are often less economical to repair than to replace, especially given how much more efficient newer systems tend to be.
Younger systems with isolated issues like a faulty capacitor, blocked drain, or refrigerant leak are usually well worth repairing. We’ll always give you an honest comparison of the two options based on the age, condition, and repair cost of your specific unit, rather than defaulting to whichever is more profitable for us.
We provide split system servicing, maintenance, and repairs to homes and businesses across the greater Perth metro area, including the northern suburbs, southern suburbs, eastern corridor, and inner-city precincts. Whether your system was installed by us or another company, we’re happy to take a look and get it running properly again.
Most residential systems benefit from at least one service per year, ideally scheduled before the peak of summer when the system will be working hardest. Commercial systems, or units in coastal or dusty environments, may need servicing more frequently.
Costs vary depending on the number of units being serviced, their condition, and accessibility. We provide a clear quote before any work begins so you know the cost upfront.
This is most commonly caused by a blocked or disconnected condensate drain line, though it can also result from low refrigerant causing ice build-up on the coil, which then melts and overflows the drain pan. A technician can quickly identify which is the cause.
This is usually a sign the system isn't running efficiently — often due to a dirty filter or coil, low refrigerant, or an incorrectly sized unit working harder than it should to reach temperature. A service will typically identify the cause.
Start with the basics: check the remote's batteries, confirm the isolation switch is on, and check whether a circuit breaker has tripped. If it still won't power on, the issue is likely electrical or component-related and will need a technician to diagnose.
Yes, we regularly service and repair systems installed by other companies, provided we can access the necessary information about the unit's make and model.
With regular servicing, most split systems last well over a decade, though this depends on usage, environment (coastal areas see faster wear), and the quality of the original installation.
We prioritise getting to breakdowns as quickly as possible, particularly during peak summer periods when a non-functioning system is more than just an inconvenience. Get in touch and we'll do our best to accommodate urgent requests.
Whether your split system needs a routine service, isn’t performing the way it should, or has stopped working altogether, our technicians can diagnose the issue and get it sorted quickly. Get in touch to book a service or repair anywhere across Perth.
