How To Prevent Air Conditioner From Icing Up
Air conditioner owners frequently report problems with ice buildup on the cooling coils and appliance casing during normal use.
Icing can be caused by poor positioning of the unit, low outdoor or indoor temperatures or clogged filters.
You can take special measures to ensure your air conditioner does not ice up during the summer when you need it most.
It will take several hours for built-up ice to dissipate.
How to Prevent Air Conditioner From Icing Up
Use air conditioner only when outdoor temperature has risen above 65 degrees Fahrenheit
Use the air conditioner only when the outdoor temperature has risen above 65 degrees Fahrenheit, or 18 degrees Celsius. Ice will start to build up on the cooling coils and casing if the air is any cooler than that.
Turn air conditioner down or off once desired temperature has been reached
Turn the air conditioner down or off once the desired temperature has been reached. Ice will start to build up when the air conditioner is cooling an already cold room. Stopping or turning down the unit will allow ice to melt if it has started to build up.
Keep furniture away from front of air conditioner

A restriction in airflow can cause ice to build up on the grille and cooling coils.
Regularly vacuum out the air filter to improve the unit's airflow.
Dust gradually collects in the filter as the air conditioner sucks in air.
You should clean the filter every month to reduce the chance of ice buildup.
Move the air conditioner to a larger room.
Units with a high British Thermal Unit or BTU rating are designed to cool big spaces and will ice up if placed in a small room.
Think about replacing the unit with a less powerful model if you need air conditioning in the room.
