3 bar suction, haven't taken discharge 20 degrees air on 30 air off in heating 7 in cooling. Seems like condensor is running well outside just not getting the duty inside! Just trying to see if anyone's had this before

So you have 30 degrees C coil temp but also 30 degrees C air off the indoor unit?

As Frank says more pressure/temps are required to help with the diagnosis.

Suggest

Discharge pressure or liquid pressure (SCT)

Discharge temperature after the compressor

Liquid temperature

Suction temperature

Suction pressure (SST)

Air on/off indoor

Air on/off outdoor

You need to see if the discharge temperature from the compressor is much higher than your indoor coil temp, if it is then start with looking at the 4 way reversing valve.

If its not then start looking at low superheat flooding the compressor which will affect the discharge temperatures.

Again without knowing the temps & pressures its just guessing
