@airbluehvac: This customer called us about a dirty sock or fishy smell coming from the air vents, even though the HVAC system was only three years old. Unpleasant odors can come from several sources. In some cases, it may be debris inside the ductwork or even a dead animal. However, one of the most common causes especially when switching from heating to cooling is a contaminated evaporator coil. When the system changes from heat to cool, the evaporator coil begins to produce condensation. That moisture can activate bacteria and buildup on the coil surface, leading to that strong dirty sock smell. 🔧 Project Highlights: ✔️ Checked the air filter ✔️ Opened the evaporator coil access panel ✔️ Inspected the coil for dirt and buildup ✔️ Applied a professional no rinse evaporator coil cleaner Using a professional no rinse coil cleaner helps break down buildup, eliminate odor causing bacteria, restore proper airflow, and improve overall system efficiency. The result is cleaner, fresher air and better performance. We also share another product option that can effectively clean the evaporator coil and help prevent unwanted odors in the future.
