Do You Have A Clogged Accumulator?
One of the most obvious signs that your A/C''s accumulator is clogged is when you experience little or no cold air from your air conditioner vents. As mentioned earlier, an accumulator keeps the liquid refrigerant from getting into the compressor. However, it does more than that. An accumulator also removes debris and dirt from the system.
