Freon has been added to my system, but its not cooling. With freon added, why does it not cool?
There are several reasons why just adding refrigerant or freon to your car’s A/C system hasn’t caused it to start blowing cold air. In fact, one of the reasons could very well be the way the refrigerant was added. Whenever adding refrigerant, it’s important to be sure that all the air is ‘purged’ from the hoses. If the air was not purged properly, the system could have become contaminated with air. Once that happens, the high side pressures typically rise and the refrigerant is not being properly cooled in the condenser. The air is actually preventing the A/C system from cooling properly. However, there are also several other reasons why the A/C system may not be cooling. To start, the most obvious possibilities should be checked first. Is the compressor engaging? Is the belt in place and tight? A fully charged A/C system can cause loose belts to slip and burn but may not turn the compressor. If the compressor clutch is not engaging, you will have to determine why. Start by checking fo
