Frozen pipes are a common issue to plague air conditioning system owners.
A frozen pipe within an air conditioning system can be caused by a few things. Generally, the evaporator coils need a sufficient amount of air flow in order to prevent this from happening. Frozen pipes can also arise from refrigerant issues. While frozen pipes within an air conditioning system can be concerning, there are steps to take when you encounter such a problem. First of all, If an air conditioner pipe is frozen there is no point in continuing to run the air conditioning system. Turn it off. This will allow the pipe to defrost. Now, the most common reason for a frozen A/C pipe is a dirty air filter. There are so many reasons why it is crucial to swap out dirty air filters for fresh air filters as often as possible and one of the reasons is the risk of having a frozen pipe. The area around the evaporator coils as well as the evaporator coils themselves may also need cleaning. If the air filter is fresh and clean and the evaporator coils seem okay, then there might be something wrong with the refrigerant levels. Devices that detect coolant levels can be purchased at an HVAC or hardware store but it might be best to call out an HVAC technician if you think that there is a problem with your coolant. No matter the reason that your A/C pipe is frozen there are steps that you could take to remedy the situation and getting the help of a professional is advised.
