Debris found within the air-conditioning system can include pollen, pet dander, dust, dirt, and other contaminant particles.

During the cooling procedure, moisture in the air condenses every bit temperatures drop, causing water vaper to catechumen into condensate. Condensate forms on the evaporator coils and eventually drips off, then is caught past the condensate pan below. As the water rolls off the coils, those pollutant particles come with it.

The drain pan is continued to the AC drain line, which allows condensate to move out of the air conditioner -information technology drains into a flooring drain located near the indoor units or outside the house. The debris particles can stick inside the pipe or pan during this procedure, and when plenty matter gathers, clogs form.
