Why is My Air Conditioning Unit Leaking Water?
When your air conditioner starts leaking water, you can do a few things to solve the problem. The first step is to clear any clogs that have formed. Check the drain line for any clogs and use a wet/dry vacuum to remove them. In addition, check the drain overflow pan for any cracks, notches, or holes. If you find any, you can repair them using epoxy. The best fix, however, is to replace the drain pan.

Rusted drain pan
If your air conditioning unit is leaking water, it is likely a result of a rusted drain pan. This can be easily repaired by using a two-pack epoxy liquid adhesive. The next step is to check for any blockages in the drain pipe. To do this, remove the drain pipe cap and check for rust. If you find any, you can remove them with a small wire brush. Then, use a solution of water and bleach to clean the pipe. This will kill bacteria and prevent mold growth.
Rusted drain pans are common problems with older air conditioning units. While cracked drain pans are relatively easy to repair, rusted drain pans may require the use of special sealants. This is because the metal is weakened and has many holes for water to fall through.
Low refrigerant charge
If your air conditioning unit has a water leak, it is likely caused by low refrigerant charge. Low refrigerant charge can lead to multiple problems, including a leaking compressor, a clogged evaporator coil, and pressure problems in the unit. Additionally, low refrigerant charge can cause a hissing or bubbling sound. Luckily, there are a few things you can do to solve the problem.
The first symptom of low refrigerant charge is reduced cooling. As the refrigerant level goes down, the compressor gets overworked. This means your AC will have a harder time keeping you cool and may even break. In order to fix the problem, you need to have your air conditioning unit checked by a trained HVAC technician. A technician will be able to seal the leak and recharge the refrigerant in your air conditioning unit. Be sure to use the proper blend of chemicals when recharging the system.
Dirty air filter
The evaporator coil of your air conditioning unit could be leaking water if you have a dirty air filter. The coil will become clogged with dirt and water and may freeze. When the ice melts, the water will overflow the drain pan. It is important to replace the filter regularly. You should replace it every three months or more frequently, depending on the manufacturer’s recommendations.
There are many reasons why your air conditioner is leaking water. If the drain pan has a crack or is missing, it could be blocked by debris. Additionally, if the air filter is dirty, it can block the drain line, which could cause a leak. Water from a dirty air filter can also cause the evaporator coils to freeze, resulting in water overflow. To prevent this from happening, replace the air filter monthly or more often if you have pets.
Frozen evaporator coil
One of the first things you should do if you suspect that your AC unit is leaking water is to check the filters. If they are dirty, the evaporator coil may freeze and begin to leak water. This can be a sign of a larger problem. You should change the filters every 60 to 90 days.
Another issue that may cause your air conditioner to leak water is a clogged drain line. This can occur for several reasons. When the drain line becomes clogged, excess water will build up around the AC unit. Excess water can also trigger the float switch in your unit, shutting it down and producing warm air. Additionally, the water that collects in the drain pan could lead to a mold odor in your home.
