Why Is My Car Air Conditioning Blowing Warm?
Car air con blowing warm? A Cranbourne West ARCtick-licensed workshop explains the common causes – low gas, leaks, compressor – and the fix.

Low refrigerant (most common)
Air-con gas escapes slowly over years through seals and hoses. Low refrigerant is the #1 reason for warm air – but simply ‘re-gassing’ without finding the leak means it’ll be warm again next summer.
A leak in the system
Tiny leaks at o-rings, the condenser or compressor seals are common. We use leak detection to find and fix the source – ARCtick licensed, so it’s done legally.
Failed compressor or blend door
If gas is fine, the compressor, pressure switch or climate-control blend door may be the cause – we diagnose the real fault rather than guessing.
