Frequently Asked Questions
Why is my split system not cooling in Sydney summer?
The most common causes are low refrigerant (from a leak), a dirty air filter restricting airflow, a faulty compressor, a frozen evaporator coil, or an electrical fault in the outdoor unit. We diagnose the exact cause and repair rather than guessing.
My split system is leaking water inside — what causes this?
Water dripping from the indoor unit is usually caused by a blocked condensate drain line, a dirty evaporator coil, or the unit being mounted slightly out of level. We clear the drain, clean the coil and realign the unit if necessary.
How much does split system repair cost in Sydney?
Cost depends on the fault and parts required. We give a fixed price before starting any work. If the repair cost is close to replacement value on an old unit, we'll tell you honestly and recommend the better option.
My split system displays an error code — what does it mean?
Error codes vary by brand. Common codes indicate refrigerant pressure faults, sensor failures, communication errors between indoor and outdoor units, or fan motor faults. We carry brand-specific diagnostic equipment to read and clear all fault codes.
Can you fix a split system that has run out of gas?
Yes — but we first find and repair the refrigerant leak before recharging. Simply topping up gas without fixing the leak is a temporary fix that will fail again within months and is illegal without resolving the leak.
