Cause 3Clogged or Restricted Coils

Both the indoor and outdoor coils need to be clear for the air conditioner to work efficently. A clogged or restricted coil will reduce air flow causing the unit to run longer. If the coils are clogged or restricted they will need to be cleaned.

Cause 4Air Filter

Cause 5Dirty Air Filter

If the air filter becomes clogged with dirt, it restricts air flow over the evaporator coils. If the air flow is reduced, the evaporator coils get too cold, which then causes the humidity in the room to condense on the coils and freeze. As frost accumulates on the coils, the frost restricts the air flow even more. Eventually, the entire evaporator coil assembly will frost over, causing the air flow to be completely restricted. If the air filter is dirty, replace it.
