Reasons For Aircon Freezing

Some people find it counter-intuitive that an air-conditioner can freeze. While it’s amusing but it also indicates that your air conditioner is not working as it should. If the air-conditioner in your home or office is frozen, it means that you are not getting the cool air. This is the time when you need to give a call to a reliable air-conditioner servicing company to discover the reasons for a freezing of the air-conditioner and get it fixed. As far as the reasons for a freezing of an air-conditioning unit is concerned, it may be due to a number of reasons as listed below.

Most Common Causes of Aircon Freezing

One of the most common reasons for freezing up of an air-conditioner is low level of refrigerant. Every air-conditioner uses refrigerants such as Freon in order to cool the air. This typically happens when there is a leakage in the air-conditioning system and the compressor has to work harder than normal which leads to the formation of ice on the pipes and coils. Therefore, it is important for you to check the level of Freon in the air-conditioning system in order to make sure that your air-conditioner is working at optimum efficiency.


Low level of coolant not only affects the overall efficiency of the air-conditioning system but may also cause permanent compressor failure. Also, if there is a leakage in the air-conditioning system, it will only get worse with time. Therefore, you should get it checked at the earliest in order to ensure that a small issue does not turn into a big problem. An experienced technician will usually perform a dye test to figure out whether there is a leak in the system and in case the leak is discovered, they will fix the leak and refill the Freon in order to keep the system running at optimum efficiency.

Another common cause of freezing of air-conditioner is improper airflow.

Proper airflow is needed around the AC unit to keep it running. Warm air is needed by the compressor to keep the temperature of the coils above freezing point and if there isn’t enough of warm air, it will lead to frozen coils. In most cases, the improper airflow is caused by dirt and dust in the filters. Therefore, it is important that filters are cleaned on a regular basis to allow good airflow.

The air-conditioning unit may also freeze when the temperature outside falls below a particular level. The low temperature outside causes air pressure to drop inside and that leads to the frozen air-conditioning unit. If the blower fan of your air conditioning unit is damaged, it may also lead to the frozen air-conditioner. A broken or damaged blower fan causes significant changes in the airflow inside which may lead to the build-up of condensation on the coils.

In simple terms, it can be said that an air-conditioning unit may freeze due to any number of reasons. Therefore, it is recommended to call a reliable and experienced air-conditioner servicing company at the earliest in case your air-conditioner unit is frozen. Ideally, you should get your air-conditioner serviced at least once each year. Preventative maintenance is the best way to enhance the life of your air-conditioning unit. Regular maintenance will discover any issues long before they turn into big problems and will save you a lot of money in the long run.

Do not make the mistake of trying to handle the freezing of your air-conditioner on your own if you do not have the necessary tools and training. It may not only lead to permanent damage to the air-conditioning unit but may also lead to injuries. So, give a call to an experienced air-conditioner servicing company to get your unit checked and get rid of the freezing issue.
