How To Know If Your Evaporator Coils Are Dirty?

Air conditioner owners need to take care of their systems often to ensure comfort and high-efficiency levels during warm days. Air conditioners that do not receive proper attention and often care malfunction in the worst ways possible, forcing the owners to contact their technician for AC repair in Corpus Christi, TX.

Of course, an owner cannot give professional attention to the systems at all times. However, they can take care of the simple parts of the system, like the evaporator coils. Treating evaporator coils is extremely simple and does not require technical equipment, but ignoring them for a long period can lead to major issues.

What Do Evaporator Coils Do?

Without evaporator coils, warm air will not get away from your home. Evaporator coils absorb the warmth in your indoor way, creating a way for the condensed air to enter and cool your home.

If the evaporator coils freeze, they will not absorb the heat, leading to various problems that owners should know about to fix the freezing problem.

Signs of a Frozen Evaporator Coil

  • Less Efficiency





If the coils freeze, the warm air will remain in your home, and your home will cool slowly due to its presence. It will cause the overall efficiency of the system to fall.

  • More Working

Since warm air is already present in your home without going out, your system will work for more hours than usual to regulate the indoor temperature. Your system will face more wear and tear, making you contact your technician for frequent AC service schedules in Corpus Christi.

  • Frost Building

If you continue to ignore the above signs, your evaporator coils will become extremely dirty and cause the dirt present in the system to freeze. The whole system will build up frost within a few days, and the system will stop working.

Why Do Evaporator Coils Freeze?

If you know the reasons for the freezing of evaporator coils, you can avoid them to prevent the freezing:

  • Clogged Air Filters

Dirty air filters cause a lack of airflow in the system. If there is lesser air in the system, the coils will not absorb any heat, ultimately freezing due to the lower temperatures. Replace your air filters regularly to avoid freezing and various other problems.

  • Dirty Evaporator Coils

The dirt from the air filters and other system parts can stick to the evaporator coils, hindering the heat absorption process and freezing the coils. Ensure to give your system a thorough cleaning at least once a month to avoid problems caused by dirt.

  • Low Refrigerant Levels

When the refrigerant levels are lower than needed, the system works for more hours and cycles, making the coils freeze. Low refrigerant levels may be due to a refrigerant leak, improper charging, or no maintenance schedules.

  • Clogged Drain Pipe

The drain pipe collects the condensation of the coils’ surface. If the drainpipe gets clogged due to bacterial growth, it does not collect the condensation, and the droplets freeze on the surface.
