the air will be hot .

actually never, it is not an easy task, you are always taking some risk, if the system is over 7 years old it is best to rework the system. flush all old oil out , change bearing in clutch seal in front of compressor , all system seals, then refill with fresh oil and freon. as a quick remedy add freon with oil and dye and sealer mix, then pray. if you continue on though and too much oil accumulates then compressor will blow, if too little oil it will sieze and destroy system leaving a 1,200 bill to restore

How do you add freon to 1994 Volvo 850?

To add Freon to a 1994 Volvo 850 you will need to buy 4 cans of Arctic Ice and one can of blue dye. Use the spray can nozzle to attach to the air conditioning compressor and add the Freon. I am a certified auto AC tech and would not recommend putting 4 cans of Freon in a car AC system all at once. If you do not have gauges then put one can of Freon (refrigerant) in at a time. Have the air conditioner turned up on high, the car running and begin adding the Freon while shaking the can. When the compressor kicks on ( you should hear the compressor click on) you should almost be finished. If the compressor cycles in and out quickly this means you need more Freon. If the compressor clicks on and runs for a minute or 2 then put no more Freon in the system.

How much does it cost to get air conditioning fluid put in your car?

I wouldn't pay anyone to do it, it'd probably by a lot more than to just do it yourself. You can get a can of it at auto zone or somewhere for about ten to twenty dollars and they should be able to tell you where the valve is that you put the fluid in. Second opinion: Your car should not need freon. If it does, then there is a leak, and it would be inappropriate to add freon without fixing the leak. Besides, it is possible to have too much freon, so you need to measure what was in the system. You need tools and equipment to do this, so take the car someplace and have it looked at.
