Central a.c. is not cooling properly,and is not pulling humidity out. Filter clean,freon at 75psi ,cold coming out of compressor any thoughts

Sometimes when humidity, is higher than normal,, they can`t keep up, also if a/c is bigger than what your house really needs that can be a problem,, maybe a portable dehumidifier would be a big help,, they work,, maybe the point that unit isn`t pulling out the humidity is what is making you feel the a/c isn`t working right,, maybe if you tell us more on what the a/c is not doing, it would help

How long has the system acted this way, since it was new?

Air conditioner is not putting out cold air, line between outside unit and house is freezing up. When we let the unit sit and the line warms up it works fine. It is a fairly new unit.

Sounds like you are low on coolant

System 6yrs old, wasn't cooling this season,freezing up at evaporator ,called service ,low on coolant,they added. Since then no freeze up, but won't cool properly or pull humidity, also making vibrating noise intermittantly and at start up.Noticed last night compressor unit wasn't level adjusting that right now.
