Refrigerant is only needed when the cooling system leaks. An evaporator or condenser coil concern is the most common cause of a central cooling system leak. Damaged coils can leak refrigerant, but refrigerant leaks can also be caused by holes or cracks in the coils, loose affixions, or a disfigured compressor. A professional will need to fix your central cooling system if it leaks refrigerant. Your cooling system lowers the temperature of your home’s indoor air by absorbing heat. As the refrigerant travels to the outdoor unit, it releases the heat it absorbed indoors. The refrigerant returns to the indoor unit, and when the coils or other components fail, refrigerant can leak out, causing your cooling system to lose its ability to cool… Several factors determine whether your central air needs Freon. An older device may need to be recharged more often than a newer one. Refilling your device depends on the style of refrigerant it uses, but professional AC repair is necessary if your central cooling system leaks refrigerant. Prior to adding more refrigerant, find the source of the leak plus repair it, as adding more refrigerant will only temporarily fix the problem. Your central cooling system should be able to maintain its charge for various years after you repair the leak.
