How to Fix an AC Leaking Water in 5 Simple Steps
Have you noticed water dripping or pooling near your air conditioner? An AC leaking water might seem like a small problem, but it could lead to serious issues if left untreated. Many people face this situation, especially during the hot summer months. But don’t worry, this guide will explain why it happens, how to fix it, and how to prevent it from happening again.
Why Is My AC Unit Leaking Water?
Your air conditioner works by cooling warm air and removing moisture from it. This moisture turns into water, which should flow out through a special pipe called the condensate line. When something blocks the process, water can leak into your home instead of draining properly.
Here are the top reasons for an AC leaking water inside:
Clogged Condensate Drain Line
The most common cause of an AC unit leaking water is a clogged drain line. Dust, dirt, mold, or algae can build up inside the line, stopping the water from flowing out. When this happens, water backs up and leaks into your home. Experts estimate that 90% of AC leaks are caused by a drain line clogged.
To fix this, try pouring a cup of white vinegar into the line. The vinegar helps clear out mold and debris. If that doesn’t work, you may need a professional clogged drain cleaning service to remove the clog.
Dirty Air Filter
Air filters keep dust and dirt from entering your air conditioner. When they get too dirty, airflow is reduced, causing the evaporator coil to freeze. Once the ice melts, it creates extra water, which may overflow and lead to leaks.
A simple fix is to replace your air filter every 1 to 3 months, depending on usage. A clean filter improves airflow, stops freezing, and reduces the chances of your AC unit leaking water.
Cracked or Rusted Drain Pan
If your air conditioner is more than 10 years old, the drain pan might be cracked or rusted. This pan collects water from the evaporator coil, so if it’s damaged, water will leak onto the floor instead of draining properly.
The solution is simple. Replace the damaged AC drain pan. New pans are usually made of rust-proof materials to prevent future problems.
Low Refrigerant Levels
Refrigerant is the cooling fluid inside your air conditioner. When the refrigerant level is too low, the pressure inside the system drops, and the evaporator coil can freeze. When the ice melts, it can cause your AC leaking water problem.
Signs of low refrigerant include weak cooling, hissing sounds, and ice forming on the coils. Only a licensed HVAC technician can fix refrigerant leaks and refill the system safely.
Broken Condensate Pump
If your AC unit is installed in a basement or a low area, it might rely on a pump to push water out. If this pump stops working, water can’t drain and will leak instead.
A professional AC leak repair company can fix or replace the pump so your system works as it should.
How to Fix an AC Leaking Water
If water leaking from AC unit, here are some steps you can take to fix it:
Replace the Air Filter
Check your air filter. If it’s dirty, replace it right away. This will improve airflow and stop the evaporator coil from freezing.
Clean the Condensate Line
Pour one cup of white vinegar into the condensate drain line to clear any blockages. For stubborn clogs, use a wet/dry vacuum to suck out the debris.
Inspect the Drain Pan
Look under your AC unit for the drain pan. If it’s cracked or rusted, replace it with a new one.
