When to Clean Your Air Ducts

There are a couple of chores that you know you have to immediately take care of. There are also some that you might be able to tackle later.

However, there are also chores that you can’t see. These types of tasks have a tendency to be ignored. One of these tasks is Air Duct Cleaning Rochester Hills MI.

If you’re lucky, these air ducts often show signs that will let you know they require your attention. Here are a couple of these indications:

Uneven Air Flow

It might be caused by debris and dust clogs developing inside the air duct system if air appears to flow with excellent strength in particular rooms, but little to no air flowing out in other rooms.

In addition to that, it might be a result of leaky ducts that have been degraded or ripped.

Dirty Interior Components and AC Coil

It’s an excellent sign that dust trapped somewhere else in the HVAC system has started to travel via the air ducts if the interior components and coils of your AC unit are filled with mildew, mold, debris, and/or dust. This will affect peripheral or external system parts.

Of course, you’ll certainly need to have your HVAC system cleaned. However, you might have to clean the whole system if the dust returns in no time.

Clogged Air Filter

If you’ve got a dirty reusable or disposable air filter from your furnace or AC system, it’s a great sign that debris and dust have started to build up around and in your system.

Visible Debris

It can be a sign that your air ducts have become clogged if you get rid of an air register and see that pet dander, dust, and other particles have built up inside the duct’s end.

Try to clean the debris and dust that you can see. You’ll probably be going to hire a professional air duct cleaning company if the debris and dust appear again quickly.

Mildew or Mold

Oftentimes, you’ll actually see brown/grey or black mildew or mold growing and/or around the exterior part of the air registers.

However, it typically presents a more serious issue with mildew or mold whenever this happens. You might have to contact a professional for help right away.


The odor is one thing that can tell you that there might be debris building up inside the air duct system.

It’s an excellent sign that your air duct system is filled with dust when you turn on your HVAC system and a tiny puff of dust came out of the air registers.
