Of the many reasons for HVAC repairs, a leak may seem like a minor issue. However, a small leak could eventually cause mold or mildew to develop or lead to electronic issues in the system. If you notice your HVAC system is leaking inside the home, here are a few possible reasons why.
Why Your Air Conditioner Might Be Leaking
1. Coil Trouble
The evaporator coils can contribute to unexpected leaks. If you run low on refrigerant or don’t replace your filters every two to three months—or more frequently if you have pets that shed—the coil could form ice, which will eventually cause leaks when it melts. Dirty exterior evaporator coils can also cause performance issues and leaks, so scheduling regular inspections and tuneups will keep them working their best.
2. Clogged Drain Line
The drain line is responsible for eliminating the condensation from the overflow pan by sending it into the drainage pipe. If the line is clogged, whether from mold or debris, water will back up in the drain pan and then leak into the system. This can be fixed and prevent future leaks by cleaning the drain lines, removing the blockage, and having a professional install an overflow shutoff device.
3. Damaged Drain Pan
Most HVAC systems come with an overflow pan that’s created to catch condensation during the machine’s operation. However, if it gets damaged or cracked, water will start to leak out into your home. In this situation, it’s best to replace the damaged pan completely.
