Why Your Air Conditioner is Frozen Again

If your air conditioner keeps getting frozen coils, it’s essential to understand the underlying reasons to prevent recurring issues and potential damage to your cooling system. American Plumbing Heating & Cooling is your reliable company for AC repair in Navarre, FL. Below, we outline some common causes for air conditioner freeze-ups.

Insufficient Airflow

Poor airflow is a primary cause of air conditioner freezing and needing subsequent AC services. When the airflow over the evaporator coil is restricted, the coil’s temperature drops below freezing, causing condensation to freeze on the coil’s surface. This can be due to clogged or dirty air filters, blocked vents, closed registers, or issues with the blower fan.

Low Refrigerant Levels

Refrigerant is the substance responsible for absorbing heat from indoor air. If your air conditioner is low on refrigerant due to a leak, don’t pull the trigger too soon on an AC replacement. It can just be because the evaporator coil has become too cold and has frozen up.

Thermostat Problems

A malfunctioning thermostat can cause your air conditioner to run continuously or cycle on and off too frequently. Both scenarios can lead to the evaporator coil becoming excessively cold and freezing. Check your thermostat settings and ensure a professional does AC maintenance.

Dirty Evaporator Coil

After your AC installation, the evaporator coil can quickly accumulate dirt and debris, reducing its ability to absorb heat and causing it to get too cold. Regular maintenance and cleaning of the coil can prevent this issue.

If your air conditioner keeps freezing up, turn off the system to allow the ice to thaw. Then, check the air filters, vents, and registers to ensure proper airflow. Regular maintenance by a professional can also help prevent future freezing problems and extend the life of your cooling system.
