Mold Growth on Your AC unit and Ducts

If your air handler is in an unconditioned space (like the attic or garage) or your return air grill is at floor level, your home could be at risk for mold growth and poor air circulation. Here’s why:

• Condensation & Mold Growth – Warm, humid attic air meets cold AC surfaces, creating moisture – the perfect breeding ground for mold!
• High Humidity & Poor Airflow – Floor-level returns pull in humid air and dust, making your AC work harder while spreading mold spores.
• Energy Waste & Health Risks – Leaky ducts, unsealed air handlers, and improper return placement lead to inefficiency and poor indoor air quality.

The Fix?

• Move the air handler to a conditioned space (if possible).
• Seal & insulate ducts to prevent moisture buildup.
• Replace floor-level returns with ceiling-level returns for better airflow.
• Add UV lights to prevent mold inside the system.
• Schedule an expert inspection to keep your AC running efficiently!
