Discount Auto A/C INC. Summary: Automobile air conditioning tips from a Master Re-Manufacturer that has re-manufactured automobile A/C compressors in Florida for over 25 years.
   Have you, or anyone you know, ever had the problem with your car's air conditioning blowing cold while driving down the road and then blow warmer at a stop light?  A lot of the mechanically inclined may automatically think "Needs Freon". But hold on just a second, let’s think about how the automobile A/C system works. Warm air that's inside of the vehicle needs transferred to the outside. That way cold air can replace it. This is made possible by compressing Freon until it becomes a gas and is very cold then pumped to the evaporator coil (underneath the vehicle's dashboard). The warm air inside of the vehicle cabin is then drawn across the evaporator coil which causes the coil and the gas inside to warm up or get hot and turns back to a liquid. then It goes through the condenser coil (usually mounted in front of the vehicle radiator) to cool before being drawn back to the compressor to be compressed again, and so on so forth..  Now, if the refrigerant isn't adequately cooled in the condenser then it stays warmer throughout the whole process. Which brings me to the point that is to be made here, when driving down the road there's adequate cooling created by air flow over the condenser coil, but when the vehicle is at a stop, the vehicle radiator fan(s) are responsible for creating the air draw required for adequate cooling. If the vehicles fans aren't working or are not drawing the proper amount of air across the condenser coils, then this is more likely to be the reason than low on Freon.
