When my aircon started leaking, I checked the usual culprits—clogged drain line and dirty filters—but the problem persisted. That’s when I realized the issue was with the installation and leveling of the unit. If your aircon isn’t properly positioned, water won’t drain correctly, leading to leaks inside your home. Here’s exactly how I fixed it, step by step.
Why Proper Installation & Leveling Matters
Air conditioners are designed to drain condensation outside. However, if the unit isn’t slightly tilted backward, the water pools inside instead of flowing out through the drain pipe. This is a common issue, especially with window-type units, but luckily, it’s an easy fix.
What You’ll Need (And Where to Get It)
Before making any adjustments, I gathered a few materials:
- Level tool – Found at hardware stores or online (Amazon, Home Depot).
- Small wooden shims or wedges – Available at home improvement stores.
- Screwdriver – Already had one at home, but you can find it at any hardware store.
- Measuring tape – Useful for precise adjustments, available at hardware or general stores.
Step-by-Step Guide: How I Fixed My Aircon’s Position
Step 1: Check the Unit’s Level
I grabbed my level tool and placed it on top of my aircon unit. If the bubble wasn’t centered or slightly tilted backward, I knew I had to adjust the unit.
Step 2: Adjust the Aircon’s Tilt
For window-type units, the back should be slightly lower than the front so water drains outside. Here’s what I did:
- Placed a small wooden shim under the front bottom edge.
- Checked the tilt with the level tool.
- Made small adjustments until the unit was positioned correctly.
For split-type units, I checked that the indoor unit was mounted evenly on the wall bracket. If it wasn’t:
- I loosened the mounting screws slightly with a screwdriver.
- Adjusted the unit so it was perfectly level.
- Tightened the screws back securely.
Step 3: Ensure the Drain Pipe is Positioned Correctly
Even if the unit is level, the drain pipe needs to be in the right position. I checked if my drain pipe was:
- Slightly sloped downward so water flows out smoothly.
- Not bent or obstructed by furniture or walls.
Step 4: Secure the Aircon in Place
Once I had the right tilt and position, I made sure the unit was stable. For my window unit, I tightened the mounting screws. If needed, you can use foam insulation or a bracket for extra support.
Step 5: Test the Aircon
I turned my aircon back on and let it run for an hour. No more leaks—problem solved!
Preventing Future Issues
To keep your aircon leak-free, here are a few tips:
- Check the level every few months, especially after cleaning or moving the unit.
- Ensure proper installation from the start to avoid long-term damage.
- Keep the drain pipe clear so water can flow freely.
I couldn’t believe how such a simple fix made such a huge difference! If your aircon is leaking, don’t overlook the installation and leveling—it might just be the quick and easy solution you need.
