Basic maintenance

The most essential task for keeping your air conditioner’s efficiency is to change or clean its filters on a regular basis. Filters that are clogged or unclean restrict airflow and reduce a system’s efficiency dramatically. Also, if airflow is impeded, dirt can skip the filter and enter the evaporator coil, reducing the coil’s heat-absorbing ability. Replacing a filthy, clogged filter with a clean one can reduce energy usage if your system by 5 to 15%.
