If your aircon isn’t cooling properly or the airflow feels weak, blocked aircon grills could be the problem. Clogged grills can restrict airflow, reduce cooling efficiency, and increase energy bills.
In this article, we’ll cover what causes blocked aircon grills, the signs to look out for, and simple ways to clean and maintain your grills for better performance.
What Are Aircon Grills?
First of all, aircon grills are the slotted covers on your aircon that allow cool air to flow into your room and warm air to exit.
They’re found on both the indoor and outdoor units.
In other words, they’re essential for smooth and efficient airflow.
When these grills get blocked by dust, dirt, or objects, your aircon has to work harder than necessary.
Common Signs of Blocked Aircon Grills
So, how do you know if your aircon grills are blocked?
Look out for these clear signs:
Weak or Uneven Airflow
Firstly, if you feel that your room isn’t cooling evenly or airflow from your aircon feels weak, it’s a strong sign the grills might be blocked.
Strange Noises
Next, blocked grills can cause air pressure to build up inside the unit, resulting in strange hissing or whistling sounds.
Higher Electricity Bills
In addition, a blocked grill forces your aircon to work harder to push air through.
As a result, your energy consumption increases, leading to higher utility bills.
Dust Buildup Around the Unit
Another common sign is visible dust gathering around the grills or vents.
This often indicates that airflow is restricted, and your system isn’t breathing as it should.
What Causes Blocked Aircon Grills?
Blocked aircon grills can be caused by several factors:
Dust and dirt buildup from daily use
Furniture or curtains blocking the air outlets
Neglected maintenance or long intervals between cleanings
Fortunately, these issues are easy to prevent with regular servicing.
How to Prevent and Fix Blocked Grills
Now, here’s what you can do to avoid this problem:
Clean Your Aircon Regularly
Firstly, wipe down the aircon grills with a damp cloth every 1–2 weeks.
This simple step prevents dust from piling up.
Keep the Area Around Your Aircon Clear
Next, make sure there’s enough space around your aircon units — both indoor and outdoor — for air to flow freely.
Avoid placing curtains, furniture, or plants too close.
Schedule Professional Servicing
In addition, regular professional servicing ensures that internal parts, filters, and grills are thoroughly cleaned and inspected.
