What Causes Musty Smell in Air Ducts?
Every time you switch on the AC, a musty odor bothers you. The musty smell is commonly instigated by mold or mildew growth in dirty air ducts. The smell no only irritates but may aggravate health problems and allergies at your home.
But what could be the possible reasons of the musty smell? Let’s try to find out –
Mold – Presence of mold and mildew in air ducts is the most common cause of the musty smell in air ducts. Mold grow when the following four conditions are met-
1. Food (dust or dirt)
4. Warm temperature
Dirty air coils are one of the most common breeding grounds of molds as they are located in the dark area and warm air constantly flows in the coil causing condensation over the coils. Dust and debris keep accumulating on the air ducts. All this results in mold and mildew growth. Regularly cleaning the air duct and by changing air filter on time reduces the chances of mold growth.
- Install a UV germicidal lamp which will prevent the growth of mold.
- Call professional air duct cleaners to clean dirty air ducts. Induct Clean team has more than 18 years of experience in air duct cleaning.
Leaky Air Ducts
• AC running for a long time but not cooling your home as needed
• Indoor air gets dirty and humid
Air ducts carry air to every part of your home. In case the air duct is leaky on its way it may draw in the outside air which is generally filled with dirt and spores. The dirty air inside can cause mold growth in the duct leading to musty smell.
Solution – You need to find the leaks and apply duct sealant to eliminate it.
More reasons of Musty Smell in Air Ducts
