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.

How to add freon in a centralized air conditioning unit


The compressor needs to be running.Also you need freon charging guages and a pressure temp chart to tell how much you need to add.
If your not sure of anything i said here have a service person do this.You take a risk of damaging the unit and yourself.

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.

Sounds like your breaker is tripping for your outside unit. Compresser could be grounded out or a breaker problem.

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

Adding freon to my central air


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 heard that there is a spray you can use that will not damage your system and seals the leak when it comes in contact with oxygen
