Keeping Your Home Cool during the Sweltering, Summer Months

2 Possible Causes Of Freezing AC Coils

by Anthony Graves

Have you noticed visible ice around your ac coils? Or, does your house feel hotter than usual, even when your AC is running? These are often tell-tale signs of frozen AC coils.

AC coils are responsible for the refrigerant evaporation process that facilitates the cooling of your indoor space. If the coils are frozen, you might have to contend with a hot and humid home.

Read on to understand possible causes of frozen AC coils.

The Condensation Drain Is Blocked

Your air conditioning system relies on the condensation drain to eliminate excess moisture from your indoor air. During this process, the drain may accumulate dirt from the evaporator. If you don't clean the drain occasionally, the drain line eventually gets blocked.

A clogged condensation drain means moisture from the air will have nowhere to go, resulting in water backing up the AC system. Eventually, the water freezes, causing the AC coils to freeze as well.

Common signs of a clogged condensation line include:

  • Uneven cooling
  • The ac unit fails to turn on
  • Awful odor due to dust accumulation and organic growth around the system
  • Pooling water around your indoor AC unit

Contact an AC repair expert as soon as you notice any of the above signs. The professional will inspect the condensation drain and unclog it if necessary.

Clogged Air Filters

Air filters are a critical component to the functionality and efficiency of your AC. Your cooling unit requires constant airflow for maximum performance. However, air must go through the air filters to get rid of dirt and other contaminants before getting to the coils.

After a long period of use, the trapped particles accumulate and block the air filters, leaving no space for air to pass through. Lack of constant airflow causes moisture to settle on the AC coils, and when the water freezes, it freezes the coils.

The best way to prevent clogged air filters is to change the filters regularly. This improves your HVAC system's efficiency by up to 15% and allows it to cool your home to the desired temperature.

If you recently changed the air filters but still have frozen coils, have an AC expert come in for inspection. The professional will check for signs of blockage or poor installation to overrule air filters as the culprit for freezing AC coils.

Frozen AC coils are a problem you can prevent with regular system inspections and repairs. Don't wait until your AC can no longer cool your home to schedule a maintenance appointment.
