Variable Speed Compressor
The 'loud' symptom combined with 'warm' air usually indicates an internal mechanical failure of the scroll members or bearings. In a variable speed unit, if the compressor loses the ability to maintain a pressure differential, it often emits a deep grinding or groaning sound while failing to circulate refrigerant effectively for cooling.

Inverter Power Assembly
The inverter drive controls the frequency of the compressor motor; if the transistors fail or the DC link is unstable, it can cause the compressor motor to vibrate violently or 'growl' at an audible frequency without successfully turning the rotor. This results in significant noise and a total lack of cooling capacity.

Reversing Valve
If the reversing valve is stuck in a mid-shift position or has an internal seal leak, high-pressure hot gas bypasses into the low-pressure side. This creates a loud, continuous 'hissing' or 'whooshing' sound and prevents the system from reaching the necessary pressures to cool the air.
