Mold in AC air vents are extremely common and appears when not doing regular cleaning maintenance. Black mold as well as other types within your AC air vents can be extremely detrimental to your health. It’s also the quickest way it can spread throughout your home – causing allergies and illness among family members and pets.
When running your air conditioner unit on hot summer days, cool air travels through the ductwork which causes condensation. The water which forms from this condensation sits and when it comes into contact with mold spores (and it eventually will) mold will inevitably form. These spores can enter the AC vent from outside or even from other parts of your home and will form into mold colonies as soon as the conditions are right.
Removing mold from AC vents can be tricky at best because of the many hard to reach places. However, it might be wise to have the substance in your AC vents tested just to make sure it is mold. This can be done by yourself by means of a DIY test kit or you could call in a professional to do it for you.
The cleaning process can start once the presence of mold has been confirmed. You will first need a cleaning solution and one of the best options in this scenario is to use a bleach mixture.
First check the insulation of the ductwork to see whether or not mold has infected the actual insulation itself. If this is the case you will have to replace the material instead of attempting to clean it.
If the insulation is fine you can commence the cleaning process by using your bleach solution to clean the AC vents. It is vital that everything gets thoroughly cleaned because if you miss even the smallest section the mold will quickly repopulate. This is easier said than done because of the many hard to reach places. If having difficulty reaching every section of the AC vents then it might be best to call in a cleaning expert who has the necessary tools to reach these places.
In the worst case scenario not every place of the AC unit can be reached and in this case attempting to clean it will be a waste of time. And this unfortunately means the entire AC unit will have to be removed and replaced.
Keeping mold out of your AC vents is the best way to ensure you have clean air circulating in your home and there are a number of steps you can follow to do this.
HEPA filters in AC unit: By fitting your air conditioner unit with HEPA filters your vents will have minimal risk from mold infection and they will remain mostly clean.
Yearly maintenance: It’s recommended to have a professional come in annually to thoroughly clean and do maintenance on your AC unit.
Monitor the situation inside your home: In many cases, the mold in AC vents comes from within your home therefore it is essential to minimize them as much as possible. If your home is humid then it might be wise to invest in a good quality dehumidifier. This will prevent excessive moisture in your home thereby preventing mold formation.
