Got snot coming out of your air conditioner’s drain line? You’re going to want to read this 👇 That white gloop is called zooglea. Zooglea is a biofilm — a complex mixture of microorganisms like bacteria, algae, fungi and other organic materials. It thrives in the dark and moist corners of ductwork, coils and, most commonly, condensate drain lines. Zooglea buildup can compromise your home’s air quality by releasing allergens and other pollutants into the air. The so-called “drain snot” can also build up and obstruct airflow, reducing the efficiency of your AC. The buildup may block drain lines completely, causing a backup of condensation that’ll shut your whole HVAC system down. Here are 6 ways to prevent and get rid of zooglea: 🔧 Schedule routine inspections and cleanings for your HVAC system. 📅 Change filters regularly, and use filters with high MERV ratings. 🧪 Consult with a professional to periodically treat HVAC components with biocides. 💨 Ensure proper ventilation in areas where moisture builds up, like basements and crawlspaces. 💧 Use dehumidifiers near your HVAC system to maintain optimal humidity levels. 💡 Consider installing UV-C light systems in your HVAC system to prevent microbial growth. - @homeserveusa
