There’s nothing quite like the relief you feel when you finally switch on your air conditioner during the hot summer months. But when your AC starts to freeze up, you may find yourself feeling frustrated and confused. After all, your AC is supposed to keep you cool, not just leave you with a big block of ice! In this blog, we’ll be discussing the common causes of a frozen air conditioner, as well as some tips on how to avoid this problem.
Dirty or Clogged Air Filters
It’s important to remember to clean or replace your air filters regularly. When the filters become dirty or clogged, they restrict airflow, causing your AC to work harder than it should. When your air conditioner works harder than it should, you increase the risk of your system overheating, which can cause it to freeze up. To prevent this from happening, it is recommended that you clean or replace your filters at least once a month.
Low Refrigerant Levels
Refrigerant is the substance used to absorb heat from the air in your home. When your AC has low levels of refrigerant, it can cause the evaporator coils to freeze. This is because there isn’t enough refrigerant to absorb heat, so the coils become too cold and start collecting moisture which freezes the coils.
Broken Fan Motor
If the fan motor that blows air over the evaporator coils is not working correctly, it can lead to a buildup of ice. Without proper airflow, the cold air from the evaporator coils won’t be able to circulate, resulting in poor cooling and potential freezing.
Blocked Airflow
If your vents, ducts, or air registers are blocked, this can cause restricted airflow, leading to a frozen air conditioner. This is another easily preventable issue that can be solved by keeping the area around your air conditioning unit clean and free of debris, making sure that nothing is blocking your vents, and regularly inspecting your ducts.
Malfunctioning Thermostat
Your thermostat controls your air conditioner and sets the temperature for your home. If it’s faulty, your system may keep running even when it’s already reached the target temperature. This often results in the evaporator coils freezing up.
In conclusion, a frozen air conditioner is a common issue that could be caused by any one of several factors.
