Well duprees, first you got to have the right instrumentation for charge freon to a a/c system, now, the charge line is the thick line, wich it means the suction line, the colder line, or the most robust line on the compressor.
Then, the system uses freon 22, the right charge, with the system on and the compressor running is 68.5 to 70 psi.
This should give to you about 40 degrees(farenheit) at the evaporator, the panel that gets cold in the system.
This pressure should be at the low side, meaning thicker line in the compressor unit.
Hope this help you......



Good luck.......

I have central air and I was wondering how do you put freon in it because its not blowing out cool air


Is the compressor starting? On the outdoor unit you will see a large copper pipe and a small copper pipe. Is the larger of the two cold to the touch? wet? Just because a central air system is not blowing cool air does not mean it needs freon. If you have clogged filters it cannot do an air exchange. So, I would recommend checking the easiest things first before adding Freon.Most people make the mistake of adding Freon and overcharge their system. In a low load situation you can slug the compressor with liquid and your system is ruined. If you do have to add Freon it indicates that you have a leak. An AC System is a closed system and if it is working properly you should not have to add Freon.

How do you add freon to a mitsubishi split system


If its R22 you have to have a license to buy it. But outside unit on the larger copper line will be an access will look like a 3/8 copper fitting with a cap on it there is also one on the small line. You will need a tank of r22 and a set of gauges. If the compressor is running you add freon til the large copper line starts to sweat. The small line (high side) should not slug or have the gage on it jump this means its overful or has air contamination in it. Always add thru the larger line.good luck

Tempstar High efficiency 5000 losing/leaking full freon tank in


this system has to have a rather large leak. for it to loose it's charge in that short amount of time, is terrible. there are leak detectors that can sense a leak as small as 1 ounce per year. I strongly suggest you get the system leak checked before putting more "Freon" in it as it will just leak out again.

How do you add coolant to a goldstar air conditioner


There are two lines leading into the unit, the high side aND THE LOW SIDE. tO ADD FREON you need to add a valve to the low side line. But if you have a leak that indicates that moisture is in the unit and you need to pull a valum to remove the moisture before ADDING ANY FREON. There are as last known three types of freon, R22, R134a and this last one I dont even know the name.

How do I add freon to my central air conditioner


Adding refrigerant (Freon is Dupont's name for refrigerant) requires some special tools and gauges. More important than that is your system should not loose refrigerant. It you are low that means you have a leak in the system. It should be found and repaired before new refrigerant is added. A qualified repair technician should be called.

Central air freezing up


Low freon causes this problem. It could be the compressor going bad, but 99% of the time it is that the freon is low, have it leak tested and also have freon added

Problem with central air condition


that depends on the size of the unit and lenght odf the line set.. to give you a general answer your suction pressure should be about 70 PSIG and you liquid line (small line) should be between 245-265 depending on the outdoor temp you will need a set of freon gauges to check this these readings are for an R-22 system if you have R-410a the readings will be much higher
