The majority of the air in your home passes through the air ducts to reach its destination. With so many sections of ductwork, it's no surprise that some of the system is likely to be vulnerable to dirt, dust and other debris. To keep those particles out of the air that you breathe, you'll want to keep your air ducts clean. Here are a few common contaminants that an air duct cleaning contractor will be able to eliminate.
Dirt and Dust
Dirt and dust particles are often blamed for a host of respiratory problems, including allergies and irritation. Some homeowners believe that if they can't see the dust, it must not be there. The truth is, if you know where to look, you can see the dust if it's accumulating in your ductwork.
If you're dusting more often than you used to, that's a sign that there's more dust in the house than before. In addition, you can watch the air vents when your heating or cooling system turns on. If there's dust settling inside the ducts, you'll see some dust blow out of the vents when the system first comes on. It's important that you have the dust and debris cleaned out, otherwise it may clog the system and obstruct air flow. This can reduce the efficiency of your climate control system.
Mildew and Mold
Since the inside of the air ducts can often be subjected to moisture, darkness and humidity. This creates a prime environment for the development of mold spores and mildew. When this happens, you'll end up with mold spores blown around your house through the air passing through those ducts. You'll know this is a problem if you're smelling even a subtle musty odor in the air when your climate control system turns on.
Particularly in the off-seasons when your climate control system is off, the air ducts provide a perfect environment for critters like mice and other small pests. Even if they're nesting in distant corners where you can't necessarily see them, you're probably seeing and hearing signs of their presence. For example, if you hear scratching sounds along the walls where the ductwork runs or you see rodent droppings and insulation shreds in the vents, those are sure signs of the presence of unwanted guests.
Keeping your air ducts clean on a regular basis will help reduce the risk of these issues. Talk with an air duct cleaning contractor today about establishing a cleaning schedule for your home's ductwork.
