As the scorching summer heat rolls in, having a functioning air conditioner is crucial to beat the heat and stay comfortable indoors. However, a common issue homeowners encounter is their air conditioners freezing up unexpectedly. This phenomenon compromises the cooling efficiency and can lead to potential damage if left unaddressed. In this blog post, we will explore the reasons behind air conditioner freezing and provide effective solutions to fix the problem.

Understanding the Causes
Inadequate Airflow: One of the primary reasons for AC freezing is restricted airflow. This can occur due to dirty air filters, blocked vents, or closed registers. When airflow is restricted, the evaporator coil can become too cold, causing condensation to freeze on its surface.
Low Refrigerant Levels: Refrigerant plays a crucial role in the cooling process of your air conditioner. If there’s a refrigerant leak or insufficient levels, the evaporator coil can become excessively cold and freeze over time.
Faulty Thermostat: A malfunctioning thermostat can lead to erratic temperature control, causing your air conditioner unit to run continuously. This prolonged operation can result in the evaporator coil becoming too cold and eventually freezing.
Dirty Evaporator Coil: Over time, dust and debris can accumulate on the evaporator coil, hindering its heat exchange capabilities. This buildup can cause the coil to become excessively cold and freeze up.
Fixing a Frozen Air Conditioner
- Check and Change Air Filters: Regularly inspect your air filters and replace them every 1-3 months, depending on usage. Clean air filters promote proper airflow and prevent the evaporator coil from freezing.
- Ensure Proper Airflow: Ensure all vents and registers are open and unobstructed. Keep furniture, curtains, or other objects away from blocking the airflow. Ensure that nothing is obstructing the outdoor unit’s airflow as well.
- Verify Refrigerant Levels: If you suspect a refrigerant leak or low levels, it’s essential to contact a professional HVAC technician to inspect and recharge the system as needed. Attempting to handle refrigerant yourself can be dangerous and may require a license.
- Calibrate or Replace the Thermostat: If your thermostat is malfunctioning, it’s best to calibrate or replace it with a qualified technician. A properly functioning thermostat ensures accurate temperature control and prevents unnecessary strain on your air conditioning system.
