Replacing an Old Aircon in Perth: 6 Signs It Is Time
Replacing an old aircon is a decision most Perth households put off until the unit dies in a heatwave. Knowing the signs that point toward replacing an old aircon, rather than paying for another repair, saves both money and a miserable summer. Here are six worth watching for.
1. Repairs are stacking up
One repair is normal; three in two summers is a pattern. When the callouts start clustering, the sums usually favour replacing an old aircon over another fix, because each repair buys less time than the one before it on a unit that is wearing out across the board.
2. Bills are climbing without more use
Efficiency drops as a unit ages and components tire. If cooling costs keep rising while your habits stay the same, that gap is the running cost of an ageing system. A newer unit can claw back a good part of it, which shifts the maths on replacement.
3. It struggles on the hottest days
An aircon that copes in October but cannot hold a room in February is telling you something. Struggling exactly when you need it most is one of the clearer signals for replacing an old aircon, especially if servicing and clean filters have not made a difference.
4. Parts are getting hard to find
Older models eventually pass out of support, and a technician quoting long waits or scarce components is a practical argument for replacing an old aircon. Waiting weeks for a part in the middle of summer is its own cost, separate from the repair bill itself.
5. It keeps tripping the circuit
A unit drawing more current than it should, or repeatedly tripping its breaker, may be failing electrically. That is worth an electrician diagnosing, because the cause could be the circuit rather than the unit, and knowing which is which decides whether replacing an old aircon is actually the answer.
6. It is simply old
Age alone is not a fault, but past a certain point most systems are living on borrowed time. If a unit is well into its second decade and showing any of the signs above, replacing an old aircon proactively beats waiting for it to fail on the worst possible day.
Replace before summer, not during
Installers get busy exactly when everyone’s aircon fails, so lead times stretch through the hottest weeks. Planning a replacement in the cooler months means choosing calmly, comparing quotes, and having it done before you actually need it rather than sweating through a wait.
The electrical side changes too
A new unit is not always a straight swap. Capacity, the circuit, the isolator and the switchboard all need to suit the replacement, and an older home may need board work to support a modern system. Getting an electrician’s view early avoids surprises on installation day.
Efficiency is where the savings sit
Newer systems are generally far more efficient than what they replace, so a chunk of the cost comes back through lower bills across Perth’s long cooling season. Weighing that against the purchase price gives a truer picture than the sticker figure alone.
When it is not a replacement question
If the unit fails with a burning smell, heat or scorching at the isolator or board, that is a fault to make safe now, not a purchase to consider. Treat it as urgent, and if it happens at night, an after hours electrician near me is the right call.
Why use a licensed electrician
The electrical side of replacing an old aircon, circuits, isolators and switchboard capacity, is licensed work. A licensed electrician handles it and coordinates with the aircon fitter, while refrigerant work stays with a refrigeration technician. The Energy Rating (Australian Government) explains how efficiency affects running cost.
