Is There Ice on Your AC? Here’s What Is Wrong

It is strange to find ice on the outdoor AC unit condenser during the summer. Ice formation is a sign that indicates that your AC system needs help from a technician to fix the issue building inside the system.

Our Air Conditioning Installation Boerne TX, advises you to switch off the AC system immediately if you find ice on the system. Operating the AC system when there is ice on the condenser fins can increase the damage and make the repair problem more complicated. It is better to switch off the system and try to remove it with the help of a sharp tool or wait for it to melt down completely. Ensure that you do not damage the condenser fins while using a sharp tool to thaw the ice.

Now, after removing the ice, let us jump to the section where we discuss the root cause of the problem. It is easy to find the solution to fix the issue after you know what the problem is in the AC system.

Reasons That Cause Ice to Form on the AC System

According to our air conditioning installation companies in Boerne, TX, here are some potential reasons why the air conditioning system starts to freeze in the summer months:  

  • Low levels of refrigerant: Refrigerant is one of the components in the AC system, without which the cooling process is impossible. Different components work on the refrigerant to cool down the room temperature. The refrigerant starts to decrease after exhaustive use of the AC system. The refrigerant absorbs the heat from the indoor air, and the air around the evaporator coils becomes cool due to the absence of heat.
    The condensate droplets on coils and in the air inside the system start to freeze if there is less refrigerant in the evaporator coils. There could be a leakage in the refrigerant coils that is causing the depletion in the refrigerant levels.
  • Clogged air filter: The system does not have enough air to work on if the air filter is clogged. The air filter absorbs the warm indoor air inside the room, and the heat exchange occurs. However, if the air filter is clogged, there is no exchange of heat, and the chilled refrigerant in the coils starts to freeze.

  • Dirty evaporator coils: Experts of AC installation in Boerne, TX, recommend that residents enroll in maintenance plans because maintenance keeps all the repair problems away. When the evaporator coils are dirty and dusty, it reduces the heat transfer rate between the indoor air and the compressed refrigerant. Again, due to inefficient transfer of heat, the coils start to freeze. 


If you find water dripping from the indoor unit, call the technician to inspect the system and find the issue. However, if ice is on the outdoor unit, then switch off the system and wait for the ice to melt away. Cleaning the condenser coils and condenser fins will solve the problem.
