Why Is There Ice on My Air Conditioning System?

The purpose of air conditioning is to maintain a cool, comfortable environment in home. Because you expect to feel cold air coming from the vents, you might at first think that ice forming along the inside of the system isn’t a big deal. After all, isn’t an AC supposed to get cold? But air conditioners don’t use ice to provide you with cool temperatures, and the air coming from your vents won’t get cooler because it’s wafting across ice. An AC doesn’t “create” cold air; it removes heat from the indoor air and shifts it outside, and that gives you the sensation of a lower temperature. If frost grows along the parts of the system where the heat exchange occurs, it will interfere with the air conditioner’s ability to absorb heat. This will reduce your AC’s efficiency and make it work harder.

Reasons ice can form on your air conditioner:

Dust and dirt accumulation: If the air filter in your AC becomes clogged or damaged, dust can start to build-up along the indoor evaporator coil. (This is one of the reasons it’s so important to change your filter regularly.) Dust that blocks the heat absorption along the coil will prevent the refrigerant inside from warming up, and it can begin to freeze over the coil. If your AC has gotten dirty enough for this to happen, it will need professional cleaning.

Low refrigerant charge: The refrigerant in an air conditioner doesn’t get used up during normal operation. But if the amount of refrigerant (its “charge”) starts to drop because of leaks, it will make it harder for the evaporator coil to absorb sufficient heat to prevent it from icing over. Refrigerant leaks need an expert to locate and seal them. Afterwards, the technician will recharge your AC’s refrigerant to get it back to its standard cooling ability.

Ice in your air conditioner is one of the most visible signs of developing trouble. Don’t wait to get it fixed: the larger the ice block grows, the worse your AC will perform.
