Firstly, what causes an AC to freeze up? If the refrigerant that creates cold air overlocks and freezes itself, your room will not actually turn any cooler. Rather, it will either blow in warm air or nothing at all. Pressure is manipulated by the refrigerant circuit- however, if something stops air from blowing over coils, or if pressure goes unbalanced inside the coils, then they become too cold and can freeze up quickly, because of the airflow, pressure, or both. Let’s have a more detailed look at why this happens:
Lack of airflow
This is the most common reason, caused due to various malfunctions, starting from blower motor to air intake. If warm air is somehow stopped from flowing over the coils while the compressor is functioning continually, your AC starts to freeze up- and this condition gets worse with time. It can happen due to
- collapsed duct;
- bad blower motor;
- low fan voltage; and/or
- clogged air filter.
Dust blockage within coils
No air filter, low quality filter and no replacement of filter have the risk of dust accumulation associated with them. The coils often damp due to moist air condensing on the cold surface, and must be cleaned on a regular basis. When air filled with dust blows past dampened coils, a thick blanket is formed, which acts as an insulator- trapping the cold air and forming excessive coldness. This, combined with more moisture, builds up on the dust, creating an “ice-box” effect.
Low quantity of refrigerant
If you’re running low on the level of refrigerant, the warm air quickly coverts into cold gas, and moisture is condensed onto coils which freezes it instantly. With the lack of pressure, more ice builds up until the AC is filled and copper pipes are creeped up. This is why maintaining appropriate levels of refrigerant is necessary to prevent freezing up of your AC.
If you notice ice anywhere around your AC, you must turn off the thermostat and call the home AC repair Dubai immediately. This allows the compressor to turn off and stop building cold air. Leave the fan on, as an added airflow might help the ice to start melting. Inform the Dubai AC company the reason behind your call, because it needs to be prioritized in order to prevent permanent damage to your system.
Our services for home AC repair Dubai ensures that by preventive maintenance, your AC keeps running smoothly, prevents freezing up of your cooling system, and functions optimally through the heat of the Summer months, so that you can relax at your home without having to face hefty expenses on replacement later on.
