temperature on suction line


Hello,

Two-year old Trane heat pump cannot keep more than 6 - 8 degrees difference between return and register (any of them), regardless of what the temp is outside.

Took the temp of the suction line at the compressor and it hovered around 65 - 70F. On the other unit (same kind and age and which is working fine) the temperature at the line was 92F.

Does anyone knows what condition (s) this may indicate. I do not have a gauge to measure 410, so I do not know the gas quantity.

thanks
