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

Air conditioners are complex pieces of machinery. To reduce your monthly expenses and maintain the system, opt for air conditioning services in Summerville, SC.

1. What Does an Ice Buildup Look Like?

It is not uncommon to detect a light coating of frost on the evaporator coil of your air conditioner while it is functioning. When that small dusting becomes a substantial accumulation of frost and ice, you might anticipate problems with your air conditioner.

In addition, you may have noticed that your air conditioner’s compressor is constantly starting, stopping, and restarting. It is known as short cycling, a dangerous sign of ice accumulation. The additional wear and tear produced by short cycling may cause your air conditioner to deteriorate over time.

2. Causes of ice buildup on AC

  • The Evaporator Coil is Contaminated

A dirty evaporator coil increases the likelihood that ice will form on your air conditioner because it lowers the quantity of air that can circulate through the unit. In addition, a dirty coil may cause the air conditioner to consume more electricity, which can be detrimental to the compressor.

To prevent a cooling system breakdown, turn off the unit and make sure the coil is cleaned or replaced. Keeping an evaporator coil clean requires routine cleaning and air conditioning services in Summerville, SC.

  • Inadequate Air Circulation

Improper air circulation is the second leading cause of an air conditioner freezing up. It simply means your air conditioner is choking since it does not have enough air to operate properly. When there is insufficient airflow, the coil temperature falls below freezing. 

The moisture in the air then condenses on the coils, resulting in an accumulation of even greater ice on your air conditioner. However, it can also be caused by a too-restrictive air filter, an insufficient number of return ducts, improperly sized or defective ductwork, and dirty evaporator coils.

  • Low Refrigerant

Your home’s air conditioning cannot operate properly without refrigerant. It begins as a liquid after ductless AC installation in Summerville but undergoes phase transitions as it passes through the air conditioning system, ultimately becoming a gas.

When there is a leak, the mixture flows at an improper speed via the numerous tubes and coils, which throws off the entire cycle. The chemical will not travel as it should and become entrapped at various points throughout the system. As the stagnant cold air continues to blow over the refrigerant, it will begin to freeze and produce a deposit of ice.

  • Broken Motors

A failing blower motor or fan motor is the final possible explanation for ice accumulation on your air conditioning system. Due to these worries, your system’s airflow may become restricted, leading to freezing. 

If your motor has failed, you will require the services of an HVAC specialist, just as you would if your evaporator coils were unclean or if there was a refrigerant line leak.
