\"frost-pattern\"Here\u2019s a common misunderstanding people often have about air conditioning systems: it\u2019s normal for ice to appear on them, because it means the AC is doing an extremely good job of cooling the air.<\/span><\/p>\n

Nothing about this is true. Air conditioners should never create ice as they operate, the same way that you shouldn\u2019t see ice forming inside a modern freezer (unless you specifically put water in it to turn into ice). When you see ice developing on your AC, it will appear along the indoor coil, the evaporator coil, and that sends a warning that something is wrong with the air conditioner. Not only is a problem present in the AC, but the ice will cause the air conditioner to provide <\/span>less<\/span><\/i> cool air, not more. In most cases, ice on the coil means you need to call for <\/span>AC repair in Flushing, MI<\/span><\/a>.<\/span><\/p>\n

The Basic Problem That Causes Ice on the Coil<\/b><\/h2>\n

If you know the rudiments of how your AC works, you\u2019ll know that cold refrigerant moves through the indoor coil. As the blower pushes warm air around the coil, the cold refrigerant evaporates and absorbs heat from the air, lowering the air\u2019s temperature and raising the refrigerant\u2019s temperature above freezing. As a side effect of evaporation, moisture condenses along the coil, then drips down into a condensate pan.<\/span><\/p>\n

However, if the refrigerant in the coil isn\u2019t able to absorb enough heat from the air, the refrigerant will remain below freezing. The moisture on the coil won\u2019t drip off; instead, it will freeze on the coil. This ice will further restrict the coil from absorbing heat, and even more ice will grow. If ice completely covers the coil, the AC won\u2019t be able to cool the air at all.<\/span><\/p>\n

Why the Coil May Lose Heat Absorption<\/b><\/h2>\n

What might interfere with the evaporator coil\u2019s job that will lead to ice growth? These are the possible underlying problems you\u2019ll need to address:<\/span><\/p>\n
