Neglecting to carry out proper maintenance is one of the most frequent causes of air conditioner failure. If you don't regularly replace the air filters and clean the coils, your air conditioner won't be able to work efficiently and its compressor or fans may break down prematurely. Dirty filters can restrict the amount of air flowing through the evaporator coil, causing it to become too cold and freeze up. To avoid this, it's essential to change your filter at least once a month.
In addition to inadequate maintenance, incorrect installation can also lead to air conditioner failure. If the unit isn't installed correctly, it won't be able to function properly and may eventually stop working altogether. Finally, if you've attempted to repair the thermostat but your air conditioner is still not working properly, the issue may be with the air conditioning unit itself.
