What you get

Likely Causes, Cheapest First

Wrong mode

The controller is set to heat or fan only. It happens after a cold snap, when nobody has touched the remote since winter.

Blocked filter

A choked filter starves the indoor coil of airflow, so the system runs but cools nothing. Established gardens around the older Castieu Estate blocks push plenty of leaf debris indoors through open doors and windows.

Dirty outdoor coil

The unit dumping heat outside cannot dump it through a coil caked in dust and leaf litter, so the refrigerant runs hot and the vents blow warm.

Refrigerant leak

Low gas means low cooling. This is licensed work, and our ARC Licence L162586 covers the full refrigerant handling side.

Failed capacitor or compressor fault

The outdoor unit sits silent while the indoor fan pushes room-temperature air around. This one needs a repair visit.

Checklist

Checks You Can Safely Do

  • Confirm the mode is set to cool, not heat or fan.
  • Check the temperature set point is actually below room temperature.
  • Slide out the filter and hold it up to the light. If no light comes through, clean it.
  • Look at the outdoor unit and clear leaves away from the coil.

Do not wait on this

When a Warm-Air Fault Needs a Technician

Call us if the filter and settings check out, or if the outdoor unit is silent while the indoor unit runs. Those point to refrigerant or electrical causes that need diagnosis on site.

Call immediately if the warm air comes with ice on the pipes, water dripping inside or an error code on the controller. Running a struggling system through a heatwave turns a small repair into a big one.

Call and we will tell you honestly how fast we can get there.
