In Cypress TX, ductless air conditioning systems offer energy efficiency and targeted cooling—ideal for our warm, humid climate. But when water starts dripping from your indoor unit, it’s more than just an inconvenience. It’s often a sign that something in the system isn’t working as it should. Here are some common reasons your ductless AC may be leaking water—and what you can do about it.
1. Clogged Condensate Drain Line
Your ductless system removes moisture from the air during the cooling process. That moisture turns into condensation, which is supposed to drain outside through a narrow pipe. Over time, this condensate drain line can become clogged with dust, dirt or biological growth—especially in high-humidity areas like Cypress TX. When the line is blocked, the water has nowhere to go and starts to back up, leaking from the indoor unit and potentially damaging your walls or flooring.
2. Dirty or Blocked Air Filters
Ductless systems rely on consistent airflow to function efficiently. When the air filters get dirty or clogged, airflow is restricted, which can cause the evaporator coil to freeze. As the system cycles off and the coil thaws, the melting ice produces excess water that the system can’t drain fast enough—leading to leakage. Keep in mind that most ductless filters aren’t disposable. They need to be cleaned regularly, especially during heavy-use seasons like summer.
3. Frozen Evaporator Coils
Frozen coils are a common culprit when it comes to leaking water. When airflow is blocked or refrigerant levels are too low, the evaporator coil gets too cold and freezes over. Eventually, that ice will melt and cause water to pool in or around your system. In many cases, frozen coils point to a deeper issue that needs professional attention, such as low refrigerant or a malfunctioning component.
4. Low Refrigerant Levels
Refrigerant is the lifeblood of your ductless system. When levels drop—often due to a leak—it can lead to reduced pressure in the system. That pressure drop causes the evaporator coil to freeze, and like other coil issues, thawing leads to water leaks.
Low refrigerant isn’t something you can top off yourself. It requires specialized equipment and training, making this a job for your HVAC technician.
