During summer, we use air conditioners to keep us cool and comfortable. After driving for a while, the air conditioner may freeze. When this happens, the cold air may not be properly discharged, and eventually, a huge block of ice may form on the evaporator coil. The airflow out of the vents is reduced as the ice begins to impede the movement of the air.

Professional heating and cooling specialists provide air conditioner repair in Ridgecrest, CAperform thorough inspections, diagnose problems and provide recommendations on how to prevent the problem from recurring. 

The Most Common Reasons For An Air Conditioner To Freeze Are:

Low Refrigerant Levels

Air conditioner refrigerants often rely on the right pressure to function properly. Under normal operation, water vapor can condense outside the refrigerant piping.

However, if the pressure changes for some reason, the refrigerant may start to operate abnormally. In such cases, the refrigerant can condense and freeze the air outside the line. 

Poor Airflow

One of the main reasons for frozen air conditioners is inadequate airflow. For example, a damaged air duct can make it difficult for the warm air in a Harrisburg home to move over the evaporator coil, causing condensation.

The compressor will continue to run, and condensed water can become ice. The experts inspect ducts for blockages and leaks, fix problems, improve airflow and prevent ice buildup. Call us! 

Clogged Air Filter

Air filters are important; their job is to keep dust, dirt, and other air pollutants out of the indoor air through the air conditioner. However, the air filter quickly becomes clogged with dirt and needs to be replaced frequently. If this is not done, they will begin limiting airflow in the air conditioner.

This blockage causes the cooled air to stay on the AC line for a long time, causing condensation and eventually frost and ice. A simple solution to this is to schedule regular maintenance. By calling us, you can avail of air conditioning services in Ridgecrest, CA.

Clogged Drain System

The HVAC system not only maintains the temperature but also removes moisture from the house. In addition, it has a drainage system that allows this extra moisture to drain out of your home.

However, if the drain pan or drain line becomes clogged, the refrigerant absorbs heat, causing water to flow back into the system and freeze in the coil. Therefore, the dirt buildup and neglect of maintenance are the reasons behind the clogging of the drainage system. 

Dirty Evaporator Coils

Dust often collects in the evaporator coil. The thick dust layer of the evaporator coil does not allow the air in the warm room to make full contact with the cold coil, which will not cool the air sufficiently, and the small amount of water extracted by the coil will freeze.

It essentially repeats the same pattern that occurs when the airflow is restricted. Therefore, the condenser will continue to operate, and the ice formation will continue to grow.
