When the air conditioner that keeps your home cool through a hot Southern California summer is working in peak condition, you’ll feel crisp cold air coming from the vents around the house. It feels almost as if the air has passed through a cavern of ice on the way to you. So if you start to notice ice and frost forming on parts of the air conditioner, it may seem almost normal.
However, it isn’t. Ice appearing on the indoor components of an AC is a sign of a serious problem affecting the system’s ability to absorb heat from the interior of the house. As soon as you notice frost forming on your air conditioner, call on professionals technicians. They will track down the reason for the ice and then take care of the necessary repairs. Don’t delay: if left unattended, this problem can cause severe damage to the air conditioner and you may end up with a completely broken down system right when you need it the most.

Reasons that ice may form on an air conditioning system
- Clogged air filter: The most common cause of an AC icing over is a clogged air filter. The filter will pick up debris over time, and unless it is changed/cleaned once a month during the summer season it will become congested. This will lower the flow of warm air into the AC, and the evaporator coil will remain too cold, resulting in the icing.
- Dirt along the evaporator coil: Should the evaporator coil become covered with dust and dirt, it will reduce the ability of the coil to absorb heat from the air. The cold refrigerant inside will remain at too low a temperature, and the moisture on the coil will freeze instead of dripping down into the condensate drain.
- Loss of refrigerant: This is the most serious source of ice developing, since it can lead to the compressor overheating. When refrigerant is low because of leaking, the evaporator coil will lose its power to siphon heat, and the remaining refrigerants will stay too cold, triggering the ice. Professionals must not only locate and seal the leaks, they must also recharge the refrigerant in the system to its proper level.
