An AC leak isn’t just annoying, it can damage your home and wallet. Did you know, 3 out of 5 homeowners experience an AC leak at some point? This article cracks the case, revealing the top suspects while guiding you toward a cool, dry resolution.
Five Reasons Your AC is Leaking Water
In this section, we’ll explore five common reasons why your air conditioner might be leaking water in your house. Read on!
1. Clogged Drain Line
The AC condensate drain line plays a huge role in removing excess moisture produced during the cooling process. As the air conditioner cools the air, water vapor condenses into liquid form on the evaporator coil.
The drain line transports this water and debris from the drain pan to a drain or outdoors. However, if dirt, mold, or other contaminants accumulate in the line, it can become clogged, leading to water backup, increased indoor humidity, and potential damage to your home.
2. Dirty Air Filter
Another common reason for an air conditioner leaking water is a dirty air filter. When the air filter becomes clogged, it restricts airflow to the evaporator coil. As a result, the coil can freeze over. Once the ice thaws, excess water accumulates in the drain pan, leading to leaks. Regularly changing the air filter helps prevent this issue and ensures efficient cooling.
3. Frozen Evaporator Coils
An evaporator coil is a key component of an air conditioning system responsible for absorbing heat from indoor air. This coil contains the refrigerant that evaporates as it absorbs heat, cooling the air in the process.
However, if the evaporator coil becomes too cold, it can lead to the formation of ice, which, when melted, may cause water leakage inside your home. Frequently clean the coil and perform refrigerant level checks to prevent coil freezing and subsequent leaks.
4. Disconnected Drain Line
Another suspect for your AC leaking water inside your home is a disconnected drain line. This occurs when the line responsible for carrying condensation away from the unit becomes detached, leading to water leakage inside your home.
The issue can be caused by poor installation, aging, or physical damage. To fix this problem, locate the disconnected drain line, reattach it securely, and ensure proper drainage away from your home. Ensure the line has a proper slope to facilitate water drainage away from the unit.
5. Damaged Drain Pan
The final suspect in our AC leak case is a damaged drain pan – a shallow tray that collects and channels away condensation produced during the cooling process. If the pan is cracked or damaged, it can lead to water leakage inside your home. This damage can occur due to corrosion, age, or excessive standing water. You might need to contact a professional HVAC technician to inspect the drain pan, repair any damage, or replace it.
Conclusion
Understanding the reasons behind your AC leaking water is essential for maintaining a comfortable and dry indoor environment. Addressing issues such as clogged drain lines, frozen evaporator coils, low refrigerant levels, dirty air filters, and damaged drain pans can prevent water damage.
