Recognizing the Causes


Several factors can add to the cold of an a/c pipeline. Comprehending these causes can help you resolve the concern successfully.

Lack of Airflow


One usual reason for a frozen air conditioner pipeline is inadequate air flow. When the airflow over the evaporator coil is restricted, it can cause the coil to go down below freezing temperature level, causing ice development on the pipe.

Reduced Refrigerant Levels


Not enough cooling agent degrees in your air conditioning system can also cause a frozen pipeline. Low cooling agent degrees can trigger the stress in the system to drop, leading to the cold of wetness on the evaporator coil.

Cold Weather Conditions


In chillier environments, freezing temperatures outside can add to the freezing of a/c pipes. If your air conditioning device is not correctly shielded or if there are leaks in the ductwork, chilly air can penetrate the system, causing the pipe to ice up.

Dirty Air Filters


Dirty or clogged up air filters can restrict air movement in your AC system, causing numerous issues, including an icy pipeline. It's important to change or cleanse your air filterings system routinely to guarantee appropriate air movement and prevent ice build-up.

Signs of a Frozen AC Pipe


Identifying the indicators of a frozen a/c pipe is vital for punctual activity.

Reduced Airflow


If you notice a considerable reduction in air movement from your vents, it can suggest an icy pipeline.

Ice Buildup on the Pipe


Noticeable ice build-up on the cooling agent line or the evaporator coil is a clear sign of a frozen air conditioning pipeline.

Odd Sounds from the Unit


Uncommon audios, such as hissing or gurgling, originating from your AC unit can signal that there's ice present on the pipe.

Immediate Actions to Take


When faced with a frozen AC pipe, it's necessary to act rapidly to prevent further damages to your air conditioning system.

Shutting off the a/c

5 Reasons Why Your AC Line is Freezing Up and How to Troubleshoot Them


There are multiple reasons why your AC line is frozen. Anything from dirty filters to refrigerant leaks can cause a frozen AC line. Not all reasons can be easily fixed at home, and you may need an air conditioning repair service to tackle chemical coolant leaks, and the malfunctioning of internal parts.



Blocked Vents


First, check the supply vents. Are there obstructions blocking the supply vents, causing the cooled air to circulate inside the unit, or are there obstructions making it difficult for the cold air to travel through the room? Obstructions, such as furniture, fixtures, and walls, blocking the air flow from the vents are some of the common reasons why your AC line is frozen.



To troubleshoot, power your AC system off. Check all the vents in both the indoor and outdoor units to see if there are fixtures or debris blocking the supply vents, and remove these obstructions. Let the frozen AC line thaw out before powering the AC system back on, then see if this solves the problem with your air conditioner line.




Dirty Air Filter and Coils


You may notice your AC unit blowing warm air instead of cool air due to a dirty air filter. Besides blocked vents, dust accumulated in filters and coils can also cause a frozen AC line as the debris locks in moisture inside your air conditioning system. As the air conditioner cools the air, it freezes the accumulated moisture surrounding the filter and evaporator coils.



Troubleshooting this problem is fairly simple. Power your AC unit off, then let the frozen AC line thaw. You may use a hair dryer to apply warm air to thaw the ice buildup faster, but this is not necessary. Remove the air filter carefully, and wash it with a combination of soap and water. Vacuum up the dust surrounding the evaporator coils.


Refrigerant Leak


A refrigerant leak is another cause for a frozen air conditioner, however, this issue cannot be easily solved at home. Refrigerant is what cools the air that goes through the air conditioning unit, and when the chemical coolant leaks out, it can freeze up the water accumulation around the evaporator coils.



Refrigerant leaks cannot be solved at home without proper tools. The coolant can be irritating to the skin and lungs, so it is best to have a professional find and fix the leak. A professional HVAC technician will use a colored dye to locate the leak, fix it, and top up your refrigerant to keep your air conditioner in good condition.


Cold Air


If the weather is cold outside, it can cause your air conditioner to freeze. An air conditioner freezes when there is enough humidity inside the unit, coupled by freezing-low temperatures outside. When this happens, your AC unit may blow warm air instead of cooled air, and you may notice ice accumulation around the evaporator coil.



To troubleshoot this, shut down your air conditioner, and check the frozen AC lines. Air conditioners often dehumidify spaces, so check whether a dirty evaporator coil is causing moisture to accumulate inside. Let the frozen AC lines thaw out, and clean the filters and dirty evaporator coil as needed. Avoid using your unit in cold weather.


Blower Fan Failure


You may notice the air flow around your unit getting weaker despite using the highest fan mode setting. This may be due to a problem with your blower fan. A malfunctioning blower fan cannot direct the cooled air out of the unit, while the exhaust unit continues to remove warm air from inside the air conditioner. As a result, the unit’s evaporator coil freezes.



For blower motor and fan blade problems, it is best to leave the issue to the professionals as they will be able to assess and determine the root cause of the problem. Have your faulty fan motor replaced, and have a professional check your air conditioner from the compressor to the evaporator coil for a thorough checkup.


Clean your air conditioner thoroughly


Wash the air filter at least once every two weeks to remove dust accumulation, and vacuum up the evaporator coils as well. Give your outdoor unit a good rinse with the garden hose on a hot day to dislodge any debris inside.


Avoid using your AC unit in cold weather


Cool temperatures can cause moisture inside your AC unit to freeze, so it is best to use the heater setting of your unit, or keep the temperature on a moderately high level to prevent a frozen AC line.


Have your unit professionally checked


Your HVAC system will benefit from a professional checkup by one of our Luce Aircon technicians. Have our technicians check your unit every 4-6 months for the best care.


Avoid overworking your AC unit


An overworked air conditioning system is more likely to break down faster. Use your HVAC systems only as needed, and let the air conditioning unit cool down after a long period of use.


Keep the vents clear


This will keep the air flow circulated around the room, and prevent the cooled air from freezing up your AC line.
