Causes of Dirty Air ducts

Your Room

The most common source of dirt streaking around AC vents is actually in the room itself. Air entering at high velocities will cause turbulent conditions, which encourages pet FUR, other allergens, dirt and dust to attach themselves on top of the wall where conditioned air flows across them without interacting too much before leaving through an outer door or venting out into another section below ground level.

Unsealed Vent Covers

The second most common cause of dirty air from your AC vents is seeping in from unsealed openings after supplying boot penetrations. Insulation particles and other contaminants are drawn into the stream, which then mixes with conditioned, leading to streaks like before!

Moisture Level

The dirt streaking on your AC System and air ducts can worsen due to excessive moisture. Little or no water can cause particles in the atmosphere around us, like dust, pet dander, and pollen, for example, to be tucked onto surfaces, whether they’re metal (like an exterior wall), wood-based products such as furniture with tight joints between parts (exterior door panels).

Wrong Air Filter

The dirty air conditioner vents you see on your ceiling may be due to using the wrong type of air filter. Make sure that whatever kind is used, it’s at least 1 inch thick. You should also ensure that they’re pleated – this will keep more dirt from getting inside and make them last longer than other types without having too many tiny gaps for dust bunnies or small insects.

Undersized Air Grills

Your air filters may be clean at regular change intervals with everyday use, but that’s not always an indication of good airflow. If you have to replace your air filter often or if the quality isn’t up to standard, it could point towards undersized return air grills on the system, which will lead to dirty ac vents, and coils and send and send more dirt through into other parts.
