what causes aircon coil to freeze

Want to know what causes the air conditioning coil to freeze? AC equipment is a very important equipment, especially if you want to live in a conducive environment. However, due to negligence and other mechanical issues, the challenges associated with AC coil freezing are numerous.

If the AC power fails, the most important step is to shut down the system for cooling. I know the situation may be bad, but fortunately, I have given some reasons that may cause the AC coil to freeze. Read and find out. Please visit Mastercool Aircon Servicing Singapore for more information.

What causes the air conditioning coil to freeze

This is a possible reason for the freezing of the air conditioning coil

Dirty air filter

It is important to understand that your air conditioner needs constant air circulation to perform its best function. However, when the filter becomes dirty, it will block the effective airflow, which indicates that the coil will become cold. In addition, the ice that forms can block effective flow, eventually hardening it into a cluster of ice, which can cause blockage. Condensation occurs, freezing the coil and immersing in water. It is generally recommended to perform a cross-check to ensure that the filter is in good condition while the coil is frozen.

Coolant leak

The refrigerant is responsible for regulating the temperature and pressure that allow it to absorb heat. Therefore, in the event of a leak, this indicates that the pressure drop will cause the coolant to absorb more heat, which will freeze the coil. When this happens, it is important to hire a professional to repair the leak, not to refill the refrigerant, because the refrigerant may leak again.

Leakage can cause pollution and is considered a hazard to the environment. Therefore, it is important to fix it immediately. As the overall performance of the system is impaired, refrigerant leakage can also cause other problems. Therefore, please ensure that HVAC professionals perform regular maintenance to check for leaks.

Bad thermostat

The thermostat is very important in communication because it is used to adjust the temperature. When they feel an abnormal temperature rise, the thermostat will ensure that the temperature has returned to a normal level to ensure that there is a steady temperature flow, so that the AC coil is never too cold or too hot.

Therefore, if the thermostat does not work, it may cause the coil to freeze. In order to prevent this from happening, it is necessary to perform regular maintenance on the thermostat and other integral components of the AC unit to ensure that the temperature is maintained at an optimal level. If this happens, be sure to replace it as soon as possible to ensure that the AC unit performs its best function.

Blocked condensate pipe

In an air conditioning unit, the discharge of condensate is very important because the water pipe flows out of the water stream formed by moisture. The condensate will be channeled through the floor drain through pipes to ensure that there is no accumulation of water. However, when the condensate pipe is blocked, water will freeze in the pipe, causing a blockage near the evaporator coil, causing AC cooling, which in turn causes the coil to freeze.

Blower damaged

The blower promotes air circulation by absorbing cold air from the surrounding environment and expelling warm air. It helps the temperature regulator to keep the air conditioner in its best working condition. When the blower fails, it means that the airflow will be disturbed, and then condensate will occur on the coil due to the obstructed evaporation.

In addition, the condensate pipe will freeze, causing more problems. This is because the heat supply in the pipe is insufficient, which can cause blockage due to condensation. Therefore, it is very important to ensure that the blower is installed correctly.

What causes the air conditioner coil to freeze? – In summary

The freezing of AC coils is a frustrating and common problem faced by most homeowners. However, the good news is that if you perform regular maintenance, you can avoid most of these problems. Therefore, you need to hire professionals to ensure that the equipment performs its best function to avoid leakage, blockage and mechanical damage. This can avoid other mechanical damage. In this way, you will save the cost of frequent maintenance and maintenance.
