The refrigerant charge is often the source of many issues that arise with air conditioners. The purpose of the refrigerant charge is to keep the coils inside the unit from freezing. The coils pulls condensation from the air and is best when operating at the dew point level. If it operates at or below freezing, it will freeze the evaporator coil. If the coils do freeze, this will result in the output of little or no cooling by the air conditioner. This result happens because there is a low level of refrigerant inside the unit. However, too much refrigerant will reduce efficiency and it will raise the head pressure. To ensure the right amount of refrigerant exists in the unit, the line leaving the condenser should be inspected and ensured that it is not frozen but full of liquid refrigerant.
Common Misconceptions About Refrigerant
Adding more refrigerant to your Milton air conditioner or heat pump will not equal better cooling. This is quite the opposite. As explained earlier, more refrigerant means increased head pressure. An HVAC professional can ensure that the unit has a balanced charge.
Refrigerant does not need to be replaced or recharged regularly as most people seem to think so. Unless the compressor burns out, the refrigerant last as long as the unit lasts. However, if the refrigerant is constantly low, then the unit should be examined for leaks.
If there is a leak, it can be easily spotted, then the leak will need to be repaired. If there is no leak present in the unit, then the refrigerant should never have to be replaced nor added to the unit. The reason is that the controlling Refrigeration Loop is a closed system, thus, it is constantly circulating.
