Ductwork moves air from your home’s HVAC system to all the rooms in your living space. When you first turn on your A/C or furnace, you might notice a musty or foul odor permeating out. If that odor persists, you should address the problem immediately. Taking action to remove air duct odors can help your family breathe easier.
A Musty or Moldy Odor
If your home smells musty or moldy, you may have mold growing in your air conditioner. Take a look at your condenser coils, as well as the drip pan. You may find mold growth in both locations. When water condensates on the coils, it provides a great place for mold to grow. The dust can also float off and down into the drip pan. If dust plugs the pan’s drains, water will remain in the pan, forming another ideal place for mold to grow.
You can clean your condenser coils to remove excess dust. Also, you should clear the drain plug in the pan. This will keep water from moving and prevent mold growth. Another possible location for mold growth is your ductwork. Check inside vents and air returns to see if you can see mold, which can occur when your ductwork sustains damage from water.
If you find mold in your ductwork, use soap or a detergent solution to clean your ducts. Then, use a solution of bleach and water to prevent mold growth in the future. It’s also important to repair any damage to your ductwork.
A Rancid Smell
When the smell coming from the ductwork is more rancid than moldy, you may have a dead animal somewhere in your system. It’s quite common for mice and other small animals to chew through ductwork and use them as avenues. Get an exterminator to deal with your pest problem, as well as the dead critters in your ducts.
