Air conditioning systems should always employ some kind of filtration system to remove dust, dirt, pollen, and other particles from incoming air before it is heated or cooled. This air conditioning system is extremely important for many reasons: it protects both your air conditioning system and your family’s health. All home air air conditioning systems share one similar quality-they must be cleaned or replaced regularly to maintain air conditioning efficiency and indoor air quality.
