Air Conditioner Freezing Up Inside or Outside Unit

Air Supply Heating and Air Conditioning troubleshooting service extends to the air conditioner freezing up. There are a number of reasons as to why the air conditioner is freezing up, some intricate physics involved, but also some pretty basic; however the Joule-Thomas Effect is generally the root of the problem. Below you will find the common reasons as to why your Las Vegas, Nevada home or business’s air conditioner is freeing up.
1) Insufficient air flow across evaporator coil: In split air conditioner systems, which are very common, the functionality is to remove the heat from the air to cool the indoor air down. The evaporator coil is where the heat exchange takes place in conjunction with refrigerant. If the airflow is insufficient, the heat exchange cannot take place. Over time, the temperature will continue to drop and the air conditioner will freeze up.
2) Refrigerant leak: With low pressure inside the system being the result of low refrigerant, the refrigerant is still trying to do its part and expand to make the cooler temperatures and compensate for the loss, sending the evaporators coils below freezing, causing the moisture in the air to free as it comes into contact with the coil; then icing up.
3) Inadequate temperature settings: Air conditioners are designed to operate with specific temperature ranges. If the air conditioner is running when the outdoor air is 63 degrees, the pressure within the system can drop and cause the central air conditioner to freeze up.
4) Mechanical failure: Different mechanical failures such as clogged filters, kinks in the refrigerant lines, and a blower fan that is not running at all or trying to operate with balance issues or dings can also result in the air conditioner freezing up.
