Common aircon problems we fix

Not sure what’s wrong? These are the faults we diagnose and repair most often. We find the cause first, then quote you before any repair work begins.

Aircon not cold / weak cooling — often low refrigerant, a dirty coil, or a failing compressor or capacitor.
Water leaking from the indoor unit — usually a blocked condensate drain or a choked drainage pipe.
Runs but won’t cool — possible refrigerant leak, faulty thermistor, or PCB fault.
Won’t switch on at all — power supply, isolator, remote, or PCB issue.
Tripping the circuit breaker — an electrical fault that needs checking before further use.
Strange noises or vibration — loose fan, worn bearing, or a mounting issue.
Bad smell when running — mould or bacteria on the coil and blower; often cleared by servicing or a steamwash.
Ice forming on the unit or pipes — low refrigerant or restricted airflow.
Blinking light / error code — the unit is flagging a fault; we read the code and diagnose.

How our troubleshooting works

Diagnose. Our technician inspects the unit and finds the root cause — one flat trip fee covers the visit.
Quote. If parts or repair work are needed, you get a clear quote within 24 hours. Nothing is charged without your go-ahead.
Fix. Once you approve, we carry out the repair — backed by our 30-day guarantee.

Our transparent repair policy

Major repairs ($200 and above): the troubleshooting fee is waived entirely — you only pay the quoted repair price.

Standard repairs (below $200 needing a second trip): we waive the diagnostic fee, but a flat $30 logistics fee is added to cover the return trip to fit your parts.

On-the-spot fixes: if we resolve it on the first visit (e.g. capacitor replacement or a quick service), the troubleshooting fee is waived 100% — you only pay for the service or part provided.

Backed by our 30-day guarantee

Every repair carries a 30-day service guarantee: if the same issue recurs within 30 days, we put it right at no extra cost.

Installed your system with us? Repairs may fall under your installation warranty — and unlike many installers whose compressor cover is the part only, ours includes compressor replacement labour and materials. See our warranty page for current coverage.

Frequently asked questions

My aircon is running but not cooling — what’s wrong?

The usual causes are low refrigerant (often a slow leak), a dirty evaporator coil, or a failing compressor or capacitor. A diagnosis visit pinpoints which, so you’re not paying to guess.

Why is my aircon leaking water indoors?

Usually a blocked or misaligned condensate drain, or a choked drainage pipe, causing water to back up instead of draining away. Common and fixable.

My aircon trips the circuit breaker — is it safe to keep using?

No. Switch it off at the isolator and stop using it. A unit that trips the breaker is signalling an electrical fault that must be checked before further use. Book a troubleshooting visit so we can find the cause safely.

Do you charge before you know what’s wrong?

You pay one flat troubleshooting fee per trip for the diagnosis. Any repair or parts are quoted separately within 24 hours, and nothing is charged without your approval. Depending on the repair, the fee may be waived — see our transparent repair policy above.

What does the troubleshooting fee cover?

One trip to diagnose up to 5 indoor and 2 outdoor units at one residential address. It does not include gas top-up, parts, or rectification works — those are quoted separately after diagnosis.

Can you repair centralised, VRV or chiller systems?

This ad-hoc service covers residential split and multi-split units. For centralised, VRV or chiller systems, contact us for a separate assessment.

How soon can you come?

Troubleshooting is carried out during our operating hours. For urgent or after-hours cases, contact us directly and we’ll advise on availability.

Is it cheaper if I’m on an annual servicing package?

Yes. Annual Servicing Package customers get troubleshooting support included, plus exclusive discounts on spare parts and repair works.
