The greater the distance between the evaporator and condenser coils, the more refrigerant is needed. Some problems come along an overcharged and undercharged refrigerant. Refrigerant concerns are serious issues in your air conditioner that should be handled by only the professionals. The general rule of thumb is in the 2-4 pounds per ton of cooling.
