Water leaking out of air conditioner can interrupt your life and damage your building. This problem generally indicates that there is a malfunction in one of the AC unit’s components or a lapse in its maintenance schedule. It is crucial to address this issue as soon as possible. If it is not resolved, your AC will not be able to cool effectively, leading to more broken components.
What Causes Your Air Conditioner to Leak Water Inside?
Condensation is a normal process in an air conditioning system, and water leakage occurs due to this process. But when that condensation doesn’t drain properly, it collects and begins to leak inside. Common causes include:
- Clogged condensate drain line: Dirt, dust and mold can clog the drainpipe and inhibit the proper water flow.
- Dirty Air Filters: If there are blockages in the filters, these can limit the flow of air through your system, which will eventually cause the evaporator coil to freeze and thaw at excess rates.
- Low Refrigerant Amounts: Insufficient refrigerant will result in lower pressure and frozen coils causing push water off the system.
- Incorrect Setup: If the AC is not leveled, there can be an improper water drain.
- Damaged Drain Pan: If the drain pan is cracked or rusted, it will not be able to hold water properly.
How to Fix an AC Leaking Water Inside: Step-by-Step Instructions
Turn Off the Power
Make sure your air conditioner is switched off for any service work. Turn off the circuit breaker or unplug the unit.
Check and Clean the Air Filters
- Take the air filter out of the unit
- Clean it with warm water and mild soap, or replace it if it shows signs of wear.
- Be sure to dry it thoroughly before reinstalling.
Inspect the Condensate Drain Line
- Use a wet/dry vacuum or plumber’s snake to clear out debris blocking the line.
- Eliminate mold and bacteria in the drain with a rinse of water and vinegar.
Examine the Drain Pan
- Check the drain pan under the evaporator coil for cracks or rust.
- If you notice damage on the pan, replace it to avoid leaks.
Ensure Proper Installation
- Make sure the air conditioning unit is level with a level. Know its position and adjust it if needed.
Inspect Refrigerant Levels
- Some issues, such as low refrigerant levels, should be addressed by a licensed HVAC technician, as working with refrigerants requires expertise.
Maintain Regular Maintenance
- Ensure you are having routine servicing of your ac so that it runs properly.
How To Prevent Water Leakage In Your Home
- Wash or change out air filters once a month.
- Flush the condensate drain line a couple of times a year.
- Have it professionally maintained at least once a year.
- Check and make sure the AC’s installation is level and adjust.

Frequently Asked Questions (FAQs)
Q: Why does my air conditioning only leak water sometimes?
A: You may have intermittent drips caused by humidity fluctuations or partial clogs in the drain line. This problem can be avoided through regular maintenance.
Q: Can I run my AC if it is leaking water?
A: This is not advisable, because leaks can damage your walls, ceiling or flooring. Switch off the unit and fix the issue immediately.
Q: What is the cost of repairing air conditioner water leakage?
A: The cost will depend on the type of leak. Minor fixes, such as cleaning out a drain line, can run less than $100, but more serious issues, such as refrigerant leaks or installation problems, can cost $200–$500.
Q: Can I repair this myself?
A: Yes, small tasks such as cleaning filters or unclogging the drain line can be performed by the home owner. But more complicated issues, like refrigerant leaks or electrical problems, need a pro.
Q: What if I don’t just ignore the water leak?
A: Challenges in ignoring leaks include the growth of mold in the walls, structural damage to the house itself and lowered efficiency of the AC, which will lead to even higher repair costs down the road.
