Mold loves to grow in dark, damp, secluded places, making heater vents and HVAC ductwork the perfect spots. Mold can create a variety of problems in your home, and as spores are circulated through the ducts, they’ll eventually settle and grow in other areas. Learn more about the telltale signs of mold in your system and how you can schedule air duct cleaning to control the issue.

How to Recognize Mold in Your HVAC System

1. Flu-Like Symptoms

Mold, especially toxic black mold, can cause flu-like symptoms. Runny nose, congestion, and headaches are a few common signs of exposure, and those with asthma, allergies, or respiratory conditions are at greater risk of experiencing difficulty breathing as a result of mold.

If these symptoms linger or become more frequent, schedule air duct cleaning. Professionals will clear mold spores and other debris that have built up in your ductwork using high-powered vacuum hoses.

2. Musty Odors

Mold often forms around in heat vents or in bathrooms. Properly ventilating these areas will reduce the moisture buildup that mold needs to grow. Open a window or use a box fan to increase airflow to these areas.

3. Mold On Air Vents or Filters

If there’s mold or mildew in your system, it will eventually form on air vents, registers, or air filters. Look for small fuzzy or slimy deposits. They can be green, black, gray, yellow, or white. You may also find mold on AC drip pans, condenser coils, and other outdoor unit components. Standing water near your unit may also be a sign that mold will eventually develop when the conditions are ideal.
