Frequently Asked Questions
Why is my ducted air conditioner blowing warm air?
Possible causes include low refrigerant from a leak, a failing compressor, a faulty reversing valve (for heat mode), a blocked air filter, or a zone damper stuck in the wrong position. We diagnose with pressure testing and temperature measurement.
One zone of my ducted system is not working — what's wrong?
Individual zone failures are usually caused by a faulty zone damper motor, a disconnected actuator wire, a failed zone controller board, or a closed manual damper in the roof. We trace the fault to the specific zone component.
My ducted system is louder than normal — what causes this?
Increased noise usually indicates a failing fan bearing in the air handler, a loose duct section vibrating against the ceiling, debris in the ductwork, or a compressor beginning to fail externally. We diagnose the source and repair.
How often should ducted air conditioning be serviced in Sydney?
Annual servicing is recommended — cleaning filters, checking refrigerant levels, testing all zones, lubricating moving parts and verifying electrical connections. This extends system life and maintains efficiency.
