Why Window Air Conditioners Ice Up

One of the most troublesome issues with a window air conditioner is whether it will begin to ice up. For the proprietor of the air conditioner is could be perplexing.

When this problem occurs most people instantly think it is the fault of the refrigerant gas. More usually the cause would be the outcome of other difficulties.

It’s typically the result of poor airflow.

Every time the airflow through an air conditioner is restricted the cooling process becomes affected. When taken to extremes the critical pressure-temperature balance of the cooling coil could be changed. When they drop way too low the cooling coils surface temperature can drop under the dew point temperature of the room. When this happens the cooling coil is going to begin operating as a fridge rather than an air cooler. As opposed to merely cooling the environment it is going to collect and hold moisture. The moisture will freeze onto the cooling coil exactly where it’ll appear as ice.

The main job of an ac unit is almost always to de-humidify, not refrigerate, the room air. By removing the moisture from the home air it gives us a feeling of comfort. To accomplish this though the heat range of the cooling coil ought to be more compared to the room’s dew point. If it is permitted to drop below the dew point the ac is going to start to provide ice.

With this info in mind the following are a number of issues that can result in your air conditioning icing up:

1. Dirty air filter.

To stay away from this change or even clean the filter of yours every couple of weeks of the cool season. If a cigarette smoker get it done every week. In order to clean filter remove from ac, damp thoroughly, and chillwell 2.0 lay in bottom part of a sink. Sprinkle detergent (laundry detergent works out well) upon filtration area. Allow by sitting for a few minutes. Add warm water to sink so that filter is perfectly covered. Soak for fifteen minutes. Remove from rinse as well as water. Allow to air dry.

2. Dirty or blocked cool coil.

An air conditioning requires regular maintenance. Typically every two or three years. Every year would be greatest, but this holds expensive until you get it done yourself. During cleaning the cooling coil must be degreased as well as washed to clear away piled up dirt and debris. Degreasing is important to get rid of some coatings on the coil. If not done greasy residue could trap and hold air borne contaminants. They will build up on the coil & affect heat transfer. If left too long this could result in the cooling coil becoming partly blocked. This tends to create a lower airflow.
