The air conditioning system on your vehicle is designed so each component plays an integral role. Essential to the cooling process is the cycling of refrigerant. Cold air is created as refrigerant is cycled from liquid to gas. However, not every component in the system is designed to come in contact with moisture. The accumulator keeps liquid refrigerant from entering the compressor. A clogged accumulator is a serious problem as air conditioning repairs can be costly. If you suspect something is wrong with your accumulator, troubleshoot your vehicle immediately to prevent further damage.

Poor Cooling Performance

The most common symptom of a clogged accumulator is little or no cold air blowing from your air conditioner vents. In addition to keeping liquid refrigerant out of the compressor, the accumulator removes dirt and debris from the air conditioning system. If the accumulator becomes clogged with dirt refrigerant will fail to properly circulate, which leads to decreased cold air.
