Ice Inside Air Conditioning Unit

A lack of airflow caused by an obstruction in the air conditioner or a blower fan motor failure is a common cause of ice buildup on the coils in the following ways.

But when there s little to no air flowing over the cold evaporator coil it quickly frosts over because there s less heat to absorb. Ice can form on your air conditioner or heat pump in any weather if the refrigerant inside it falls below freezing. The following are some of the key reasons why your ac may be freezing up. If you have ice on your outdoor unit turn your system off check for problems and contact a professional to repair any damage.

A blower pulls in air from your home and over that coil cooling the air. The refrigerant in your air conditioning often depends on the right pressure to function properly. Ice on your hvac unit wastes energy and it can cause damage or failure. There are two main reasons that you may find ice build up on your air conditioning unit.

When an air conditioner stops producing cold air it could be affected by a number of problems. One of the most common issues is that the coils have iced over. Air conditioners are designed to function in a very specific temperature range. Ice can form on the air conditioner if the evaporator coil is dirty.

Deicing the unit properly to avoid damage takes time but performing some. If the coil is dirty the system should be switched off until the evaporator coil can be cleaned or replaced. Ice can form on the unit and stop it from cooling if the air conditioner is too large for the room or requires cleaning. As your air conditioner runs condensation gathers on the coils and is frozen by the cold air circulating through them.

A completely clogged air filter can block incoming air from reaching the evaporator coil while leaves and yard debris can do the same for the condenser coil. This is usually caused by a dirty or clogged air filter and can often be remedied by a simple change or cleaning of the filter. When the refrigerant inside a central air conditioning unit falls below 32 degrees fahrenheit humidity that surrounds the coils freezes. As your air conditioner s evaporator coil drops below freezing the moisture in your air will freeze as it comes into contact with your coil causing it to ice up.

The coils become encased in ice and the air conditioning. Continuing to operate the unit can damage the compressor and other parts of the system. If the damage is severe you may have to replace the entire system. First you may have insufficient airflow over the evaporator coils.
