How do I add freon to my window air conditioning

Jun 25, 2009

- Hi,

Still if you want to know procedure :-

First you need to be EPA certified. You need to know what kind of refrigerant. [ R22 R143a etc. ] On a home system a good set of gauges and connect properly on a 22 unit low side is blue, suction line is larger in size pipe. High side red smaller diameter. Connect both hoses check pressures if their is no reading the compressor is not running. If compressor is running on a 22 unit the high side red should be 225 to 275 should not go above 350 psi or it will cause damage your unit more or cause a rupture low side should be from 60 psi to 80 psi don't go any higher to much freon is no good and will cause higher temp. Be careful because were talking high pressures you should have a certified tech. do this if you add freon you must have a leak it dose not evaporate their is no winter summer freon its a sealed system and should never need refrigerant.

You can add freon to the low side of your a/c. When the gauges are attached to the system, you can use the third hose to attach to the freon can. Make sure you leave the can upright so as to add only the gas. Don't turn the freon can upside down to add liquid as this can lock up the compressor and then you will have to call the a/c guy out to fleece your wallet.

Detailed procedure is :-
