The question is: Do you charge AC on the high or low side? Whenever an AC system can’t cool well, it’s time to refill the system with a new refrigerant and start over.
On the high or low side? This is important: You need to know that the high sidefitting is between your AC compressor and condenser, which is the bigger of the two fittings.
However, you need to check the service manual to see where the low-side service port is.
With just one line or gauge, you will use the low side of the can of refrigerant. Also, if you want to know more about AC and how much it costs to get rid of freon from a car, read this.
Do you charge AC on high or low side HVAC?
The liquid line can be used to charge the system. If there is a king valve, you can use the liquid line to charge the system. But if not, then go to the suction machine and get some air.
It’s not always possible to charge into the high side, so at some point you’ll have to switch over to the low side.
But if you are installing refrigerant in a working system, only use the low-pressure port to charge the gas.
You should also charge liquid into the discharge gauge port or even the liquid gauge port after you’ve done a repair and drained the refrigerant. Then, when you start the unit, you should switch to vapor charging and charge it with vapor.
As long as the low-pressure port isn’t used at any time, the valves in a recipe can get broken.
Compressors can get stuck when they aren’t being used or when oil is washed out of the sump.
Can You Charge Ac On High Side?
No, you can’t. But while adding refrigerant, the high side should not go above 350psi. If it does, stop adding refrigerant and let it stabilize, and if it doesn’t stabilize, spray water on the condenser to lower the pressure.
However, if you want to open the 6Nm cap, you’ll need a 17 or 19mm deep socket. However, be careful not to over tighten it when you are tightening it.
Keep in mind that the pressure reading from the low side should be between 25 and 30 psi, and the high side should be between 200 and 250 psi. It’s possible that there are problems with one or more of the parts inside the AC. If the AC low side is high, the high side is low.
It could also be that there is too much Freon going to the evaporator, which could cause it to not work.
There could be an issue with the orifice tube. There could also be a failed thermal bulb that doesn’t pick up the temperature.
Notice that this tube is a valve that controls how much refrigerant is going to the evaporator. It works like an expansion valve.
In this case, more refrigerant goes to the evaporator when its opening is bigger than usual. This means that now there will be pressure differences in the air.
Also, when the o-ring seal outside the orifice tube wears out, this same problem comes up, as well.
Before you decide to buy a new compressor, you should check the pressure switch, the expansion valve, and the compressor clutch, among other things. When it comes to the switch, though, it’s close to the expansion valve.
While you use an Ohmmeter to see if it is giving the correct reading, look at it. This is another thing you should look at. Make sure that when you turn on your AC, your compressor clutch starts to move.

This means that if all of these parts seem to be working fine and the AC low side is hot and the high side is cold, then you may need to change the compressor to fix the unit.
What Happens If You Charge Ac On High Side?
The low side of your AC may be too high and the high side may be too low. If this is the case, note that you may have a problem with the low side being too high and the high side being too low.
If this is the case, it means that there is something wrong with the air conditioning unit itself.
Can You Charge Ac In Cold Weather?
People sometimes see their cars not cool as well as they should at the end of the summer. It could be that you were so busy that you didn’t have time to think about it when you needed to use the air conditioner. Can it be done in winter? Things you should know:
Charging your AC When It is Above 75 Degrees
A lot of experts say that you should wait until the temperature is at least 75 degrees before having your car’s air conditioning unit recharged, or even more. The process of refilling the Freon or refrigerant, topping off the AC, or recharging the AC is called a lot of different things, so make sure you know what it is.
However, no matter what it is called, it is very important to wait until the weather is warmer outside. Indeed, the refrigerant’s weight will change when it is cold outside because it will shrink in the cold. If it is cold outside, this will cause it to give off bad readings. This makes it hard to figure out how much you already have in your system, how much you need, and how much you added in when you added these elements.
Charging your AC When It is Below 75 Degrees
Even in the middle of winter, there are times when someone can’t wait for the weather to get better, and their car’s AC needs to be recharged. As long as you wait until it is 75 degrees outside, a mechanic can recharge the system if you do all of the right things at the right time.
He or she will have to keep the car warm and heated in a garage. Then, the mechanic will have to warm up your AC system and the refrigerant they are using to make sure they work well. Remember that refrigerant does expand a little when it gets hot. This means that when they refill your system, they will have to take this into account because of this.
