If you’ve noticed water pooling around your air conditioner or dripping from the unit, it’s not just a nuisance—it’s a red flag. A leaking AC can be a sign of several underlying issues, and ignoring it can lead to bigger problems down the road.
What Causes an AC to Leak?
There are a few common culprits behind a leaking air conditioner, and understanding them can help you respond quickly. Read this guide from our cooling services pros for common causes and solutions.
- Clogged Condensate Drain Line: This is the most common cause. Over time, dirt and debris can block the drain line, causing water to back up into your home.
- Damaged or Rusted Drain Pan: The drain pan sits beneath your evaporator coil and catches condensation. If it’s cracked or corroded, water can escape.
- Dirty Air Filter: A clogged filter restricts airflow, which can cause the coil to freeze. When it melts, it can overwhelm the drain system.
- Low Refrigerant Levels: Low refrigerant causes pressure drops in the system, which can also lead to coil freezing and eventual water leaks.
What You Should Do If You Notice a Leak
Once you spot a leak, it’s best to act fast to prevent water damage and system strain. Here are a few immediate steps you can take while waiting for a professional:
- Turn off the thermostat to stop further leaking and reduce the risk of damage.
- Clean up any pooled water to avoid floor or ceiling damage.
- Check your air filter—if it’s visibly dirty, replacing it might help reduce strain on your system.
Remember, leaks are often symptoms of larger issues within the system that need professional attention.
Preventing Future Leaks
Regular maintenance is key to keeping your air conditioner running smoothly. Keeping filters clean, scheduling annual tune-ups, and having your drain lines flushed periodically are all smart habits that go a long way in preventing future leaks.
