A water leak from your air conditioner can be a frustrating and worrying issue, especially in hot climates like Las Vegas. Not only can leaks lead to costly repairs, but they may also indicate underlying problems with your AC unit.
Here’s a look at some of the most common reasons why your air conditioner might be leaking water and what you can do to resolve the issue.
1. Clogged Drain Line
One of the most frequent causes of water leakage in air conditioners is a clogged drain line. The drain line removes the condensed water from your AC’s indoor unit. Over time, dust, dirt, mold, and debris can accumulate in the drain line, eventually blocking it. When the drain line is clogged, water backs up and can leak into your home.
How to Fix It: You can try clearing the blockage with a wet/dry vacuum to remove debris. Regular maintenance and cleaning can prevent this issue from happening in the future. If the clog is persistent, an HVAC technician can help ensure a thorough cleaning.
2. Dirty or Blocked Air Filter
A dirty or blocked air filter restricts airflow to your air conditioner’s evaporator coil, causing the coil to freeze. When the frozen coil melts, excess water can leak out of the unit. This is particularly common if filters haven’t been changed in a while, as dust and debris can accumulate quickly, especially during heavy usage.
How to Fix It: Check and replace your air filter regularly—most filters should be replaced every 1-3 months. Not only will this help prevent water leakage, but it will also keep your air conditioner running efficiently, saving on energy costs.
3. Low Refrigerant Levels
When your air conditioner’s refrigerant level is low, it reduces pressure in the system, which can cause the evaporator coil to freeze. Once the coil starts thawing, it can lead to excess moisture, which then leaks from the unit. Low refrigerant levels are often a sign of a refrigerant leak, which can also cause the AC to underperform.
How to Fix It: If you suspect low refrigerant, it’s essential to call an HVAC professional. They can diagnose the issue, fix any leaks, and refill the refrigerant to the correct level, ensuring that your AC functions properly and prevents water leakage.
4. Broken Condensate Pump
For air conditioners installed in basements or other low areas, a condensate pump is often used to help push water through the drain line. When this pump breaks or malfunctions, water can’t flow out as it should, resulting in a leak. Condensate pumps may fail due to electrical issues or wear and tear over time.
How to Fix It: A broken condensate pump may need repair or replacement. An HVAC technician can inspect the pump and determine the best course of action. Regular maintenance can help extend the lifespan of your pump and avoid this issue in the future.
5. Improper AC Installation
Sometimes, improper installation can be the root cause of water leaks. If an air conditioner isn’t installed at the correct angle or lacks proper insulation, condensation may not drain out as it should. For example, if the unit isn’t slightly tilted back, water can pool and overflow from the drain pan.
How to Fix It: If you suspect installation issues, consult a licensed technician to inspect the unit and adjust its positioning. Proper installation is key to preventing leaks and ensuring optimal AC performance.
