Keeping Your House Mold-Free By Protecting Your Ductwork

Construction & Contractors Blog

The effects of indoor mold exposure are not just limited to allergy-like symptoms such as skin irritation, headaches, dispnea and nasal congestion. Consistent exposure to mycotoxin-producing molds can also result in serious effects such as cancer, pregnancy complications, pulmonary bleeding and immunologic disorders:

Air conditioning problems

Air conditioning systems are notorious for having mold prone conditions. The dirt and moisture combinations found within these systems usually make them vulnerable to mold attacks. This is so especially when it comes to the duct systems that central air conditioners use to move air within a home. Therefore, if you want to ensure that your loved ones are protected from the effects of mold, getting rid of these mold-friendly conditions from your air duct system should be one of the first steps to take.

Air filters

Placing well-functioning air filters, and properly maintaining them is a step in the right direction so far as keeping your home mold-free goes. This is because filters help to keep dust particles out of your air conditioning systems. This is great in that it helps ensure that your loved ones inhale dust-free air. It also helps to keep the accumulation of dust particles in the air ducts at a minimum. And with no dust layers to grow on, this will discourage the growth of molds in your air ducts.

Duct leaks

Improper installation of air ducts, especially at joints, can let in unfiltered air into the air conditioning system. This can also occur when the ducts wear out with time. Why is this bad? Because this air bypasses the air filtration system of your air conditioning system. It therefore enters with all the impurities contained in the external environment. This air will therefore encourage the build-up of dust in the ductwork. This may then encourage the growth of mold.  

If you want to keep your home safe from a mold attack, you have to seal any duct leaks with tape mastic as soon as possible.

Roof leaks

The fact that the air travelling from the evaporator through the air ducts is saturated with moisture already poses a risk of creating mold-friendly conditions within the duct system. Add to this the moisture from a roof leak and you have conditions that encourage a full-blown mold attack. This is so especially if your air ducts contain insulation.

If you notice any signs of a roof leak, fix it as soon as possible. And if your air duct insulation is showing signs of rotting or a mold infestation, replace it as soon as possible. This will go a long way in helping to keep your loved ones in a healthy environment. To learn more, contact a company like Metro Air with any questions you have.
