Frequently Asked Questions

When an AC fan runs but produces no cold air, it typically means the refrigeration cycle has been interrupted. Potential causes include a tripped compressor breaker, a blown motor capacitor, an electrical PCB error, a blocked outdoor coil preventing heat rejection, or a loss of refrigerant gas caused by a pipe leak. A professional diagnostic inspection will measure system pressures to confirm the fault.

Turn the system off immediately at the wall or circuit breaker to protect internal electronics and prevent plasterboard damage. Leaks usually occur because dust and mould slime have blocked the gravity condensate drain pipe, or because the evaporator coil froze due to restricted airflow and is now melting rapidly.

An immediate trip suggests a short circuit or earth leakage, often caused by a burnt compressor winding, a dead short on an outdoor fan motor, or moisture ingress into the outdoor isolator switch. Never force a tripped safety switch back on repeatedly, as this can cause severe electrical damage or fire.

Flashing LED lights on the indoor fascia or alphanumeric codes on the wall controller (e.g. U4, E6, F3) indicate internal safety protection lockouts. These codes give our technicians an immediate clue regarding which circuit—such as outdoor thermistors, DC inverter voltage, or communication wires—has triggered the shutdown.

Repair costs vary depending on the diagnosis. A standard on-site inspection fee applies to attend your property and systematically test electrical, mechanical, and refrigerant systems. Once the root cause is identified, our technician provides an upfront itemised quote covering required parts and labour before any repair work commences. Minor repairs like capacitor replacements or drain clears are very cost-effective, while major repairs like compressor replacements require a careful cost-benefit assessment.

If your unit is under 8–10 years old and the repair cost is a fraction of replacement, repairing is almost always the right decision. However, if your system is over 12–15 years old, uses discontinued R22 refrigerant, or has suffered a severe compressor burnout, upgrading to a modern energy-efficient inverter model will reduce electricity bills and eliminate repeated repair expenses.

Residential air conditioners in Adelaide should receive a comprehensive professional service at least once a year. The optimal time is during spring before intense summer heatwaves arrive, or in autumn to prepare reverse cycle heating for winter. Commercial systems running extended daily hours should be serviced quarterly or semi-annually.

Yes. A dirty air conditioner with caked aluminium coils and choked filters restricts airflow and prevents heat transfer. The compressor must run longer and draw higher electrical current to reach your target temperature. Professional cleaning and sanitisation can improve efficiency by up to 20–25%.
