With that said, however, this is only a temporary solution if there's a leak. Unless you find and fix the leak, the newly recharged freon will likely leak back out. So, find and fix the leak, and then recharge it with more freon. Room Temperature Air One of the most characteristic symptoms of low freon is the presence of room temperature air blowing from the vents.

Visible Leaks Of course, another sign of low freon levels is a visible leak. Problem is, refrigerant gas is a powerful greenhouse gas, and most of it eventually gets vented back into the atmosphere. Car manufacturers were forced to convert to gases with less global warming liability, as well as sharply curtailing the amount of refrigerant on board. Generally, when you bring in your car for an AC recharge, the technician will start by checking system pressures with his gauges.

If the system is just a little low, he can start looking for leaks right away. If the system is too low or completely empty, refrigerant will have to be added to look for the leak. So, a full AC recharge involves evacuating the old refrigerant, and then refilling it with fresh. Otherwise the technician has no way to determine if the correct amount is on board.
