Overview
A frozen coil is not an isolated issue; instead, it’s as common as the common cold. Any AC can suffer from this problem and here are some of the reasons why.
Lack of Airflow
Your air conditioner needs enough airflow moving through the system to keep the coils warm and perform their job. When there isn’t enough airflow moving across the evaporator coils, the system’s temperature drops, which results in frozen coils. A typical cause of this problem is a dirty filter, which task is to keep dust, dirt, and debris from entering your AC. When the filter is clogged, airflow is compromised, rendering the air conditioner inefficient.
Refrigerant Issues
Sometimes, even when the filters are clean, your cooling system can still suffer from frozen coils and refrigerant problems can be the culprit. When your AC, for some reason, loses some of the refrigerant, it will inevitably freeze your evaporator coils. The refrigerant is the compound that absorbs heat from your home and provides air conditioning for you and your family. It works with the other components of your AC such as the compressors and evaporators. Without it, there would be no cool air coming off of your air conditioner’s grills.
Contrary to popular belief, the refrigerant in an AC does not get used up. When it loses some charge, it means that there is a leakage somewhere in the coils. If the air conditioner is low on refrigerant, be sure to call a qualified technician who can detect and seal off the leaks. Otherwise, the system would lose refrigerant all over again. If you just fill up refrigerant, not only is it a waste of time and money, it also harms the environment, especially if you have the now-obsolete R22 refrigerant.
Extremely Low Outside Temperature
When seasons change, it is common for AC units to freeze up, especially when the outside temperature is lower than the thermostat setting on your air conditioner. In order for your AC to effectively cool your home, the temperature inside must be 6 to 7 degrees lower than the temperature outside. Otherwise, you can just use the AC’s fan mode to let the cool air from the outside in.
A Damaged Blower Fan
Your AC is equipped with a blower fan to help establish the right airflow within the system. It produces air movement to the space that is being cooled. As the air cools inside your AC, it becomes jammed, preventing it from doing its job. The blower fan is the part that takes away the hot air from your home and circulates the cold air inside. The ability of your air conditioner to produce cool air depends entirely on the unit having the right balance of airflow and pressure. Therefore, the blower fan needs to be in tip-top shape.
However, when your blower fan breaks, it significantly compromises the airflow within the AC’s indoor unit. As a result, ice will eventually build up on the coils, and the water droplets will not evaporate or drain properly. If neglected, this can lead to more serious problems, so it is recommended to call your preferred HVAC company to repair the unit.
