AC units freezing up are some common problems faced by many people. An AC to run properly needs an adequate amount of airflow so as to keep the coil from freezing. When the AC regulates the air circulation in your home, it uses the warm air from your surroundings to keep the coil at a balanced temperature and helps keep the temperature from freezing. If this flow of air is interrupted, the coils freeze up before even the condensed water is drained from the unit.
A frozen coil can happen due to multiple reasons and if you are not sure why it is happening, hire an AC technician to fix it for you. Air conditioning repair in palm city or whichever area you live in is easy to find.
If you are facing cooling problems with your AC, here are some reasons that may be causing your AC to freeze up.
Refrigerant leaks
This is one of the common causes of cooling problems with your AC. Refrigerant is the substance that flows through the coil of your AC and is responsible for maintaining the temperature and pressure of the AC so as to be able to absorb heat. When there is a leak in the refrigerant, the lack of pressure causes the coil to absorb more heat than necessary, which results in the coil to freeze over.
When you face such issues, it is good to hire a professional to take care of the refrigerant leak.
Broken fans
If your AC fan isn’t pushing enough air through the unit, it will disrupt the airflow and cause the AC to freeze up. If your fan blades are dirty, it will hinder the smooth flow of air, which can cause the coil to freeze up. A broken fan motor, too, impedes the flow of air, which can lead to the AC freezing up. If you have cleaned your fan and the problem still persists then you can hire a technician to figure out if your fan motor is broken. If it is, then replace the fan and motor to make your AC run evenly again.
Inadequate airflow across the evaporator coil
If your house has a split air conditioner system, this conditioner is designed in a way that absorbs the heat from within the house and thereby drops the temperature subsequently.
So, if the AC’s evaporator coil isn’t receiving enough air from inside the house, then it will lead to a frozen coil, which in turn will freeze the air in your home. When the air conditioner does not blow enough inside air, then the proper heat exchange does not take place, causing the coil inside to freeze up.
Mechanical failures
Any mechanical failures inside the AC coil too can cause the AC to freeze up. Say there is a slight crack in the refrigerant line or the blower fan isn’t working properly, the ductwork has leakages or the fan is simply dirty. All these types of mechanical failures can cause an obstruction in the flow of air leading to a frozen AC coil. Regular AC maintenance is a must and can help keep these failures in check and prevent your AC from freezing up or causing any other discrepancies. If you are facing any cooling issue hire a professional service to check your AC for any issues.
Temperature variations
Your AC runs smoothly at a certain pressure and temperature levels. The optimum summer thermostat temperature is considered to be 78 degrees Fahrenheit while the optimum winter temperature should be 62 degrees Fahrenheit. Too much variation and it can disrupt the running of your AC. Now, when the temperature outside is below 62 degrees and you are running your AC, then the pressure inside your AC unit drops leading to your air conditioner freezing. If you are facing cooling problems with your AC, get the thermostat checked and replace it if necessary.
