Why Do I Have Mold in My Air Ducts?

Air Duct

Having mold in your air ducts isn’t a rare occurrence. There are multiple ways this can happen to you.

Signs of Mold

One sign of mold in your air ducts is a musty smell in your house after your HVAC system comes on. You may see visible mold in your air conditioner’s drip pan. Another sign is if your family develops symptoms like nausea, itchy eyes and headaches.

Oversized AC Unit

Having an AC/heating system that is too big for your home can also result in mold in your air ducts. An oversized AC unit may cool your home too quickly, which means it doesn’t have time to dehumidify your home. This can lead to moisture building up in the air ducts, which creates an ideal place for mold to grow.

GVEC of Gonzales, TX, installs HVAC systems. We always make sure we install the right size unit for your home.

Temperature Set Too Low

If you set your temperature too low when cooling your home, mold can grow around the vents. The vents are where warm and cool air meet, which can cause condensation on surfaces. If the surfaces don’t get the chance to dry out, mold will grow. It takes a temperature difference of about 20 degrees for this situation to occur.

Leaky Ducts

Most homes have leaky ducts, which lets warm air enter your ducts in the summer. Just like setting your temperature too low, this causes a situation where warm and cool air meet. Mold loves damp, temperate areas, so you may have a serious problem on your hands.
