Facts And Functions Of An Aircon Unit Vent

What is an Aircon Vent?

The aircon vent is a small opening inside the aircon unit that lets fresh air from the outdoors come in and refresh the stale air in your room. This is also helpful when you want to exhaust out any smoke or unpleasant odor from your room. You can toggle the aircon vent open or closed depending on your situation.

Aircon vents are mainly responsible for maintaining your home or office’s air pressure. Additionally, these small openings also keep you safe by filtering out debris that can make its way into your space. Installing one on your ceiling or wall can also save you from potential additional costs down the line.

When should I replace an Aircon Vent?

It is recommended that the vents of the aircon unit be replaced after 15-20 years. After this time they are likely to experience no problems which will mean they will eventually need to be replaced. Other factors which will influence the chance that the vents will need to be replaced are:

Visible Damage – mold, cracks, and other visible damages that are on the vents should encourage them to be replaced. Especially if there is mold buildup, the air quality can be negatively affected by damaged vents.

Higher Energy Bills – one reason the energy bill might have increased is from blocked or broken vents. When this happens the entire aircon unit has to work harder to push the air out around the home. This means it uses more energy and will cost more to run simply from damaged vents.

Poorer Air Quality – if the air inside the home is not as fresh or clean then this might be from the vents. If they are blocked or broken, then dirt, dust, and more can flow around the house decreasing the air quality.
