Freezing up of the air condition is caused by a number of factors such as not enough air flow, changing temperatures, defective blowers and other factors. To stop your air conditioning from freezing up you have to get to the root of what is causing it so that you can be able to know what to do so that you do not have a repeat occurrence. Make sure you charge the system correctly so that it can be able to work efficiently. You should also check whether you have leaks so that you can have them repaired immediately.
Check whether the wiring is done properly and there are no loose fitting or friction of wires and contact a technician if there is such a problem. Use the system when the temperatures have cooled down because it tends not to function properly if the temperature is less than 60 degrees. Clean the filter often because a dirty one tends to restrict air flow. You can also replace it if you feel it is not functioning properly.
