Always to the low pressure side. The low pressure side fitting is normally near the dryer ( large silver canister).
Freon is typically added to the low-pressure side of an air conditioning system. This is because the low-pressure side is where the refrigerant is in a gaseous state, allowing it to absorb heat effectively. Adding refrigerant to the high-pressure side can lead to overcharging and potential damage to the system. Always consult the manufacturer's guidelines for specific instructions on your system.
Charged on the low side service port. If you connect a small can of Freon to the high side with the system on, the can may explode from the high pressure introduced into it.....
R134a goes into the low pressure port

Freon goes into the low pressure side of the air conditioning system. The attachment from the gauge used to put the freon in will only attach to the low pressure valve so it would be pretty hard to do it incorrectly.
Connect a freon gauge and can to the low side AC port. Start the car and turn the AC on high. Open the freon valve and fill the system to full on the gauge reading.
high side goes to condenser fan coil on roof low side is the evaporator si de the coil thathas a blower to blow cold air in your house on your init it should have l or hby vavles WATCH OUT high side has very high pressure when chargeing adding freon do it with low side can of freon is marked gas or liqued try to charge by gas liqued can be done but without experience you could hurt you unit
You recharge an A/C system by adding freon through the Low side port. Look for the L on the cap. Never recharge on the high side. Too much pressure on this side and your freon can might explode. OK, once again it's not freon! it's R134a refrigerant that should be used to fill your car system. Many people call it freon but you need the r134a refrigerant( and oil, too). Anyway, freon cans are only available to certified mechanics in most states now.
Yes the ac lines are under pressure. The high side is under dangerously high pressure. The Freon needs to be removed by a reclaiming machine and the pressure will be removed.
The freon fill valve on an International 4700 truck is typically located on the refrigerant lines near the compressor. Look for two service ports: the low-pressure side is usually on the larger diameter line, and the high-pressure side is on the smaller line. The low-pressure fill valve is the one you'll use for adding refrigerant. Always ensure the engine is off and the system is properly serviced to avoid any hazards.
It depends on the outside temperature but the average low side pressure should be around 35 to 40 psi and the high side should be no higher than 250 psi..........
Freon is added through the low side ac port. A gauge is recommended to check the Freon pressure, as too low or too high pressure can cause the ac not to work properly.
