Why Is There Ice on My AC?

why is there ice on my ac

As bizarre as it may sound, ice can accumulate on the outside of an air conditioning unit in Florida. This is never a positive sign. When the unit is running at full capacity, moisture contained in the air can rapidly freeze and condense on the grill, cooling coils, condensate lines and other parts. When ice buildup occurs, you may notice that your air conditioner is only blowing warm air. If there is ice on the outside unit, it may also be accumulating on the coils inside the air handler.

What to Do When There’s Ice Buildup on Outside AC Unit

If you notice a small amount of ice, you can protect your AC by switching the unit to the fan-only setting. Without the coils operating, the ice should melt. Turn the unit off if it has a thick coating of ice. Next, check to see whether dirt or debris is blocking airflow around the unit. If not, replace your air filters. Clogged filters can cause the unit to work harder to produce the same level of comfort.

When You Need a Professional Air Conditioning Service

Ice can be a sign of insufficient refrigerant, commonly called Freon, although your unit might actually use a different coolant than Freon. The coolant is the part of your system that collects heat and transfers it outside. Over time, you may lose some refrigerant, which causes the unit to work less efficiently. You need a qualified licensed HVAC technician to check the level and add more refrigerant if necessary. It is important that you have the entire unit checked for leaks to prevent a loss of refrigerant in the future.

In addition to clogged air filters, the evaporator fan may be spinning too slowly or not at all. In each case, the fan motor will need to be serviced. Other causes of poor airflow include clogged or leaky ductwork, which requires duct cleaning and sealing.
