Is your air conditioner freezing up? If you're a homeowner, chances are you have encountered this with your system. Unfortunately, not everyone has the knowledge and skills to handle this problem when it occurs. Air conditioner freezing can inconvenience you, and you don't want this to happen. It would be best to contact a professional air-conditioning repair as soon as possible to avoid this. What can cause your air conditioner to freeze? Here are common reasons. 

Poor Airflow

Your air conditioner needs constant airflow to prevent humidity from settling and freezing on the coils. One of the best ways to keep airflow in your home is by ensuring the air filters don't get clogged and aren't dirty. 

Air filters are essential for your system, and it would help if you updated them regularly. You also want to clean your AC thoroughly and tune it up to prevent possible airflow issues. Here are common problems that may lead to a lack of airflow:

• Clogged air filter
• Bad blower motor
• Collapsed duct
• Sensor problems

Incorrect Fan and Thermostat Settings

Sometimes when you set too low fan speed with the thermostat set to a low temperature, there could be an improper transfer of heat to outdoors. You may want to set a low fan speed to reduce the appliance's noise. However, if you notice the air conditioner struggles to reduce the indoor temperature, it would be best to run the fan's speed reasonably. This is critical for air circulation through the coils. 

In most cases, turning up the speed of the fan can prevent ice buildup. When should you set a low fan speed? You only want to do this when there's high humidity outside and your system has difficulties drying the room. This can allow your unit to dehumidify efficiently. 

Compressor Issues

Your air conditioner's compressor should be efficient for proper pumping of the refrigerant. If it's ineffective, the coils may not cool well to shut off the appliance's cold control. This means the temperature may maintain at a level that's likely to cause your unit to shut off automatically. 

Dust Blocking the Coils

If you operate your machine with a low-quality filter or without one, it could lead to issues. Due to the condensation of moist air on the cold surface, your air conditioner's refrigerant coils may become damp. A thick buildup could develop as the dusty air blows past the coils. This can lead to excessive freezing within your unit. 

Your air conditioner can enhance your home's comfort, and you should ensure it functions optimally throughout the year. If you notice it's freezing up or has any other issues, don't hesitate to contact an air-conditioning repair technician for inspection and recommendations.
