Aircon leakage water is a common issue that can cause problems. This article will discuss eight common aircon leakage water issues and how to repair them.
We’ll also give some useful hints on preventing aircon water from leaking. Don’t put it off any longer – read this blog post and act right now if you have aircon water leakage!
1. Dirty or Clogged Air Filter
One of the most common causes of aircon leakage water is a dirty or clogged air filter. When the air filter is clogged, it prevents air from flowing properly through the system, which can cause the evaporator coils to freeze.
As the coils thaw, water can drip onto the floor. To prevent this from happening, check your air filter regularly and replace it when it’s dirty.
2. Faulty Drain Pan
Another common cause of aircon leakage water is a faulty drain pan. The drain pan collects water that drips from the evaporator coils. If the pan is cracked or damaged, water can leak onto the floor. You’ll need to replace the drain pan with a new one to fix this problem.

3. Leaks In The Condenser Coil
A variety of factors can cause leaks in the condenser coil of your air conditioner, but the most common culprit is simply dirt and grime. Over time, the outdoor unit of your AC can accumulate dust, dirt, and grime, which can clump together and damage the condenser.
If you notice a leak in the coil or a pipe leaking water from the back of the unit, it’s important to seek professional assistance right away. Simple cleaning will suffice in most cases, but more serious leaks may require repairs or replacement parts.
Regardless, it’s always best to let a trained technician handle any leak in your AC, as even a small leak can cause extensive damage if left unaddressed.
4. Overflowing Drip Pan
If your air conditioner has an overflowing drip pan, it can cause water to leak onto the floor. The overflow pan is designed to collect water that drips from the evaporator coils.
However, water will spill onto the floor if the pan is full. You’ll need to empty the overflow pan and make sure it doesn’t get full again to fix this problem.
5. Improper Installation
One of the most common causes of aircon leakage water is improper installation. If your AC unit isn’t installed properly, it can cause all sorts of problems, including leaks. Be sure to hire a qualified technician to install your AC unit to prevent this from happening.
6. Loose Pipes
Over time, vibration from the compressor can cause pipes to loosen at their joints. Water can begin to leak out if this happens, often causing extensive damage. To prevent this problem, it’s essential to check the condition of your air conditioner’s pipes on a regular basis.
If you notice any looseness, be sure to have them tightened as soon as possible. Doing so can help to avoid costly repairs down the line.
7. Cracks In The Unit
If there are any cracks in your air conditioner, it’s important to have them repaired as soon as possible. These cracks can be caused by several things, including age, wear and tear, or even debris.
If the cracks are small, they may not be a big problem, but they could cause significant damage to your unit if they are large. In addition to causing leaks, these cracks can also cause the unit to overheat or make strange noises.
If you suspect that your air conditioner has cracks, it’s important to have it inspected by a professional as soon as possible. Left unchecked, these cracks can quickly lead to more serious problems.
8. Worn Gaskets
Gaskets are used to seal the connection between two parts of your air conditioner. Over time, gaskets can become hard and brittle, eventually developing cracks and leaks. If you notice that your air conditioner is leaking water, it’s important to check the gaskets for wear and tear.
If they are damaged, they will need to be replaced. In some cases, you may be able to repair the gaskets yourself. However, it’s generally best to leave this job to a professional. Otherwise, you could end up making the problem worse.
9. A Broken Pump
A broken or damaged water pump is one of the most common reasons an air conditioner will leak water. The water pump is responsible for circulating the refrigerant throughout the AC unit, and if it becomes damaged, it can cause the refrigerant to leak.
In some cases, a broken water pump can also cause the AC unit to overheat, damaging other components and leading to a loss of cooling power. If you suspect that your AC unit’s water pump is damaged, it’s important to have it repaired or replaced as soon as possible. Otherwise, you may find yourself dealing with expensive repairs down the line.
10. Leak in Refrigerant
One of the most common reasons for a leaking air conditioner is a refrigerant leak. Your air conditioner cools your home by circulating a Freon-based refrigerant through a closed system of coils and fans.
Over time, this refrigerant can leak out of the system, causing your air conditioner to lose its cooling power and become less efficient. In some cases, a refrigerant leak can also cause water to build up in the air conditioner’s drain pan, leading to spillover and water damage.
If you notice that your air conditioner is leaking water, it’s essential to have a certified technician check for a refrigerant leak as soon as possible. Otherwise, you may end up facing costly repairs down the road.
