As ironic as it may sound, yes, it is possible for a cool air generating appliance to be a victim of its own function. Simply saying, air conditioners can freeze. As fascinating as it seems to see your air conditioner covered in ice or frost, this situation definitely is not a good indication of a fully functioning AC unit. As complex as it seems to think about, a freezing air conditioner cannot provide you the cool air that you want. It is advised that upon observation of any signs of freezing, you should address the problem immediately for when left alone, this situation could lead to the damage in your ceilings, walls, and to your own AC unit.
There are so many identified reasons as to why an air conditioning unit starts to freeze, but the most common are as follows:
Improper airflow
AC units requires proper flow of air in order to give warmth to the cold coil. AC units need warm air too for the coils to remain cold, keeping the temperature always above freezing point, in the absence of warm air, coils will freeze even before the water that is condensed be extracted outside the AC unit. Over the span of use on these AC units, it is not surprising that dust and dirt have already accumulated in the filters and registers impeding airflow. It is of best interest to have the filters and registers be checked for an open and clean filtration and registration.
Low level of refrigerant
A low level of refrigerant can also cause the coils too be so cold to the point of freezing. It can also cause freezing because there is now lower pressure levels in the unit itself. And since there is reduced Freon too in the system, there will be a forced need to expand without changing the amount of expansions is equal to cooler temperatures. Moreover, when the fans are faulty, air movement is blocked.
Temperature outdoors
Using the AC unit when the temperature outside is lower than 62 degrees, then pressure on the inside of the system is going to drop, causing freeze up on the AC units.
Mechanical problems
Your air conditioning unit is an appliance that uses different components molded into one. With this said, when one of the many components will fail, then the whole air conditioning unit will be affected. So in situations where your air conditioning unit has freeze, then it is best to check fort the possibly faulty and problematic component such as refrigerant lines, blower fans that does not run or is clogged, and unbalanced. These components can also change the pressure inside your air conditioning unit that will make the whole air conditioner to freeze up.
When faced with problems such as a frozen air conditioning unit, it is best to hire AC repair services provider that is equipped with the best AC professionals, having the best tools and equipment to perform a wide range of Aircon service Singapore in the most effective and efficient way.
