The Hidden Danger of Rusty Drain Pans in Your AC System
The Hidden Danger of Rusty Drain Pans in Your AC System
Most homeowners don’t think about the drain pan inside their air conditioning system — but this small component plays a big role in protecting your home. When it becomes rusty or corroded, it can lead to costly damage and dangerous conditions. At Uptown Heating & Air Conditioning in Houston, we’ve seen firsthand how something as simple as a rusty drain pan can cause big headaches.
What Does the Drain Pan Do?
The drain pan sits under your evaporator coil and collects condensation as your AC removes humidity from the air. That water then flows safely out of your home through a drain line. But when the drain pan is rusted or cracked, water doesn’t drain properly — and that’s where the danger begins.
The Dangers of a Rusty Drain Pan
1. Water leaks and property damage: Rust weakens the metal, eventually causing holes and leaks that damage ceilings, walls, flooring, and even furniture.
2. Mold and mildew growth: Standing water from a failing drain pan creates the perfect environment for mold and mildew, harming indoor air quality.
3. System damage: Water can back up into the system, damaging the blower motor, electrical components, or the furnace beneath the coil.
4. Health risks: Rust particles and mold spores can circulate through your ductwork, aggravating allergies or asthma.
