The suction line will be the larger line going into the compressor.
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
Big.

The proper suction pressure of any air conditioning or refrigeration system is determined by the type of refrigerant used and sometimes the amount of charge. : Suction pressure used is also directly related to the temperature required. : The temperature required in the evaporator relates to the pressure required in the suction line since, the fluid is at saturation in the evaporator. : Knowing the temperature required, use the fluid's saturation tables to find the corresponding pressure required.
Read the charging chart specific to the unit. Not all 410A machines will operate at identical pressures in identical conditions.
the big line is the suction for the the compressor in the A/C unit, The small line is the compressor discharge that goes to the furnace
The suction line is the big one. This line should be cold when the unit is on. The small line is the liquid line.
A suction line is usually cold to the touch.
On the low side service port coming off the back of the a/c compressor on the suction aluminum line........
The larger line is suction. The larger line is the suction side which should be on the right side of the compressor......
It is common practice to specify the pump suction line one size larger than the pump discharge line in order to increase the Net Positive Suction Head available (NPSHA) to the pump. A smaller suction line the same pipe size as the discharge line would result in more pressure drop in the suction line and reduce the amount of head available to the suction side of the pump. This in turn would result in an operating point closer to cavitation of the pump.
