Causes of AC Leaking Water

A refrigerant leak is a widespread source of condensation on the evaporator coils. If this condensation isn’t drained properly, it will eventually overflow and cause your air conditioner to leak water.

Another common culprit is a dirty air filter. When your AC unit’s air filter gets clogged with dust and debris, it restricts airflow and causes the evaporator coils to freeze up. As the ice melts, it forms a puddle of water that leaks out from underneath your AC unit.

A damaged drain pan or clogged drain line are also possible sources of an AC leak. The drain pan is designed to collect any excess moisture from the evaporator coil so that it can be safely drained away from your home via a dedicated drainage line connected to your HVAC system. If either component becomes cracked or blocked by dirt or debris, then you could end up with an overflowing drain pan and an unexpected puddle.

If the compressor of your air conditioning unit has ice forming on it. Low refrigerant levels prevent heat transfer inside the unit, leading to excessive frost buildup on both indoor and outdoor components, resulting in melted ice dripping onto whatever surface lies below them, including carpets. To fix this issue, it is best to contact an HVAC professional who can inspect and repair any potential issues with low refrigerant levels before they become more serious problems later on.

Key Takeaway: A refrigerant leak, a clogged air filter, or an issue with the drain pan can all be the causes of water leaking from your AC unit. Low refrigerant levels may also result in ice forming on the compressor and dripping onto surfaces beneath it. An HVAC professional should be contacted to inspect and repair any potential issues before they become more serious problems later on.

Preventative Measures for AC Leaks

1. Change Your Air Filters Regularly. Changing your air filters is one of the most important steps you can take to prevent AC leaks. Dirty air filters can cause your AC unit to work harder than it needs to, leading to excess strain on the system and potential leaks. Fortunately, air filters are inexpensive and easy to replace, making this an affordable and straightforward maintenance task.

2. Clean the Condensate Drain Line. Over time, the condensate drain line in your AC unit can become clogged with dirt, debris, and other materials. This can cause water to back up and potentially leak from the unit.

3. Ensure Your Drain Pan Fits Your Unit. The drain pan is an important component of your AC unit that collects water and sends it down the drain line. However, not all drain pans are created equal, and using the wrong size or type of drain pan can cause problems. To ensure optimal performance and prevent leaks, ensure your drain pan fits your AC unit.

4. Use Bleach to Keep Your Drain Line Clean. Microbes like algae and mold can grow inside your AC unit’s drain line over time, leading to clogs and leaks. To prevent this, pouring bleach into your drain line every six months or so is a good idea. This kills any microbes and helps keep the drain line clean and clear.

5. Avoid Overworking Your AC Unit in Hot Weather. When the weather gets hot, it’s tempting to crank up the AC as high as it will go. However, this can strain your AC unit excessively and potentially lead to leaks. To avoid this, set your AC to a reasonable temperature and avoid overworking the system. This will help prevent leaks, save energy, and reduce your environmental impact. Also, make sure you have the right size HVAC system for your home.

Conclusion

It is important to remember that an AC leaking water can signify something more serious. Examining and rectifying any issues with your AC system promptly can help avert costly fixes.
