Black mold in your air vents can cause a variety of unpleasant symptoms and health problems.
What causes mildew on air conditioner vents.
And the sooner the better.
Either way it s supposed to make you comfortable and that s not possible if there s an unpleasant musty smell coming out of your vents.
Common symptoms and health problems caused by black mold may include.
Mildew is a type of fungus that grows in damp and humid areas.
As cool air flows through the vents on hot days the moisture in the air can condense inside the air vent.
Condensation forms in the coils and ducts as cool air circulates through the system creating a habitat for moisture loving mold.
This happens with your air conditioner because when you have cold air and cold vents but hot air on the outside condensation will form.
Air conditioning vents can transport mildew to any room in your home.
If you live in a wet climate such as a southern state or tropical country it is likely that you ve had to clean mildew off your bathroom walls basement floorboards or even from behind your wallpaper.
Occasional condensation on a c ducts is not a problem but keeping an eye on the situation is recommended.
Persistent ductwork sweating may eventually lead to water damage.
Air conditioner vents can be breeding grounds for black mold.
Short cycling occurs when an oversized air conditioner blasts your home with cold air then shuts down quickly.
Excessive condensation can also create conditions favorable to mold or mildew forming in areas surrounding the duct itself.
Air conditioning systems trap tiny particles that settle in the filters over time and cause mildew growth when exposed to moisture.
Luckily this issue can be treated and corrected.
You can see the same principle at work when you drink an icy beverage and water beads up on the outside of the glass.
When the cool air from the vents meets the warm air in the room the temperature difference can cause moisture in the air to condense on surfaces in and around the vents.
Condensation can then drip down and cause moisture on ceilings and walls.
Mold in air ducts most commonly occurs when there is moisture inside the ductwork.
If your air conditioner is oversized it means your ac won t run long enough to remove moisture from your home s air.
If your air conditioner s filter is dirty and clogged this may result in your ac smelling musty.
When that moisture meets dust in the evaporator coil or ducts mold mildew can form.
