Has Your AC Frozen Up? 3 Places You Should Troubleshoot

A healthy AC unit helps you maintain comfort during extreme weather conditions. More so, a working unit will help you achieve comfort during hot and humid days without breakdowns and the need for repairs. On the other hand, when the unit starts to malfunction and lower its efficiency, you will have stuffy rooms, poor indoor air quality, and high energy bills, among other issues. For example, freezing is a common issue, and here are three reasons you could be dealing with the problem. 

Restricted Air Flow

Inadequate ventilation is a common cause of a frozen unit. In this case, condensation forms on the evaporator coils if the warm air inside your home has trouble circulating over them. You should know this form of airflow restriction results from factors such as faulty air ducts and blockages in the system. When the obstruction happens, the compressor will keep running, and the moisture in the air may eventually freeze. So, if you're having trouble with airflow or have seen ice building in your ducts, have an AC repair technician look and determine what they can do to fix the problem.

Loss of Refrigerant

Ice buildup on your air conditioner signifies low refrigerant levels or a refrigerant leak. You should know that low coolant levels hinder optimal system operation and can cause water vapor in the vicinity to condense on the coil's surface due to the lowered pressure. In most cases, a leak in the system is to blame when refrigerant levels drop. So, have a professional inspect your AC to fix a leak in the system. They will locate, repair it, and regas your unit, resolving air conditioning freeze-ups.

Blockage in the Condensate Line

Your AC removes excess heat from your home and transfers it outside. On the other hand, moisture from the same air drains away in the form of condensation and through the condensate drain line. So, if you notice a drip tray overflowing, it is a sign of a blocked drain. Further, the moisture will form ice crystals if the evaporator coil surface is below the freezing point. In such a case, you should have a professional flush and clear the condensate drain line to ensure that your system is operating as it should. More importantly, maintaining your AC system will prevent this problem and keep your unit running efficiently.

These are the reasons your AC system might freeze. So, speak to an AC repair technician immediately after you realize the system is developing such weaknesses. They can help you troubleshoot and resolve the problem quickly to avoid unit failure or costly repairs.
