Top Reasons Why Air Conditioners Freeze Up

Let’s dive into the top reasons why air conditioners freeze up and what you can do about it.

Low Refrigerant Levels

One of the most common causes of a frozen air conditioner is low refrigerant levels. Refrigerant is essential for cooling your home by absorbing heat. When the refrigerant is low, the pressure in the system drops, causing the evaporator coil to get too cold and freeze up. If you suspect low refrigerant, it’s important to have a professional air conditioning service provider check and recharge your system.

Poor Airflow

Your air conditioner relies on proper airflow to function efficiently. When airflow is restricted, usually due to dirty filters or blocked vents, the evaporator coil can become too cold and freeze. Regularly replacing your air filters during air conditioning maintenance and ensuring your vents are clear can help maintain optimal airflow and prevent freezing.

Dirty Evaporator Coils

Over time, dirt and debris can accumulate on your evaporator coils, insulating them and preventing them from absorbing heat effectively. This can lead to the coils becoming too cold and freezing. Scheduling regular maintenance to have your coils cleaned can help avoid this problem and keep your system running smoothly.

Thermostat Issues

A malfunctioning thermostat can cause your air conditioner to run longer than necessary, leading to the evaporator coil freezing. If your AC unit runs continuously without shutting off, it’s a good idea to have your thermostat checked by an air conditioning replacement and repair professional.
