The Hidden Culprit: How Rust from Evaporator Coils Can Clog Your Drain Line

Updated: Apr 27

When it comes to your air conditioning system, out of sight should never mean out of mind. One often overlooked culprit of AC woes is rust from evaporator coils. As your AC unit cools your home, moisture condenses on the evaporator coils, creating the perfect environment for rust formation. Over time, these rust particles can break loose and find their way into the drain line, causing frequent clogs and potentially damaging your system.

Rust particles from evaporator coils pose a persistent threat to your AC's drain line. As condensation forms on the coils during the cooling process, it carries rust particles along with it. These tiny particles may seem insignificant at first, but over time they can accumulate and create blockages in the drain line, hindering proper drainage and leading to issues like water leaks and mold growth.

Regular maintenance is crucial to prevent rust-related drain line clogs. Schedule annual inspections with a qualified HVAC technician to ensure that your evaporator coils are clean and free of rust buildup. Additionally, consider installing a drain line filter or pan treatment to trap rust particles before they can cause problems downstream.

Don't let rust from evaporator coils wreak havoc on your AC system. Stay proactive with maintenance and take steps to protect your drain line from clogs. By staying vigilant, you can keep your AC running smoothly and avoid costly repairs down the line.
