If you have problems with a heat pump heating very well. Here are some things you can try.
Unit is over or under charged, unit is undersized for job, metering device problems,poor air flow discharge will be hot and you will hear pulses from the compressor in the refrigerant lines, indoor coils dirty head pressure will be high, outdoor coils dirty suction pressure will be low, compressor is weak suction pressure will be higher than normal. In heat mode a dirty coil will rob efficiency and raise head pressure.
If in doubt call a professional
