A Frigidaire window air conditioner that grows ice on the coil or drips water into the room is usually dealing with restricted airflow, a bad tilt, or a drain that is plugged. Start with the simple items below.
Why Window Units Ice Up
Ice forms when the evaporator coil gets too cold and the moisture on it freezes. The usual reasons are:
- A dirty filter that restricts air across the coil.
- A very dirty coil behind the front grille.
- Running the unit at its lowest setting during cool, humid nights.
- Low refrigerant, which needs a sealed-system repair.
Turn the unit to fan only for a few hours so the ice melts. Put towels under the front edge, because a thick sheet of ice sends a lot of water into the room as it melts.
Why It Drips Inside
A window unit should tilt slightly toward the outside so condensate drains out the back. If it sits level or leans inward, water runs into the room. Check the tilt with a small level. A plugged drain hole in the base pan, often blocked by dust and algae in humid weather, causes the same problem.
What We Check and What We Cannot Say From the Sign
If the filter, the coil and the tilt are fine and the unit still ices, the cause may be a failing fan motor, a weak capacitor or a refrigerant leak. Ice alone does not tell us which. We measure airflow and electrical values first, and we tell you before any sealed-system work whether it is worth doing on that unit.
We service plug-in window and portable units only. Ducted and mini-split systems need a licensed HVAC contractor, and we say so when a call turns out to be one of those. Older window units are often cheaper to replace than to open up, and we tell you when that is the case.
You can book by phone or the online form, and we confirm a three-hour arrival window. See our room air conditioner repair page.
