Before you can understand why your AC unit is leaking, it is important to understand how an AC unit works. Air conditioners operate by transforming one phase of matter into another. When gas changes to liquid, it releases heat. An air conditioner uses a refrigerant contained in its tubing to encourage the phase conversion process. Refrigerant is pulled through the compressor in the form of vapor. The compressor increases the density of the vapor and removes heat. The vapor travels through the air stream and runs over the condenser coils. It is then vented to the exterior side of the building.
Air conditioners also act as a dehumidifier. Moisture is removed as the warm vapors travel over the cold evaporator coils. This process is like that of a radiator in your vehicle. If any of these parts break, become clogged, or fail, you will experience water leaking inside and/or outside your home.
There are a wide variety of reasons why your window AC is leaking outside. Is the drain blocked? Is the air filter dirty? Does the AC have grime or mold build-up in the drainpipe?

Air conditioning units are responsible for removing humidity from your home. It is difficult to cool an area with high humidity. Part of the cooling process is removing this humidity. The drain line removes the condensation and humidity. It drains water out of the unit. Over time, the drain pipe can become clogged. The water will back up and spill out of the drain pan. This will result in a leak.
When you come home and find your AC is leaking, you should check the drain line. The drain line is one of the most common reasons your AC is leaking. It is an easy and affordable fix. An HVAC technician will use equipment called a wet/dry vacuum. This vacuum will remove any mold, dust, or dirt build-up and clean your AC’s drain line.
After discovering a puddle of water on the floor, you may wonder, “why is my AC leaking water” or “why my AC is leaking water outside.” It could be due to a dirty air filter. When the air filter becomes clogged, moisture will build up in the AC unit. A dirty air filter can also cause negative health side effects and be detrimental to those with allergic respiratory disease.
According to the US National Library of Medicine and the National Institute of Health Trusted Source Effectiveness of Air Filters and Air Cleaners in Allergic Respiratory Diseases: A Review of the Recent Literature Recent studies of various types of filtration, used alone or as part of more comprehensive environmental control measures, are reviewed. www.ncbi.nlm.nih.gov , “Air filtration is frequently recommended as a component of environmental control practices for patients with allergic respiratory disease” (Sublett, 2011). The research displayed a direct link between cleaning air filters and improving the treatment of allergic respiratory disease.
If your window AC was installed incorrectly, it could cause leaking. The AC must be installed properly as the manufacturer instructs.

Expert HVAC professionals will advise you a small amount of water in your window AC’s drip pan is normal. It should not raise concern. How an AC works, as discussed previously, will cause the warm vapor molecules to condense and form water. The water collects into the drainpipe, through the drain hole, and into the drip pan. The condenser pump will remove the water once the water reaches a specific level. If the condenser pump is broken, it will not trigger water removal. The water will overflow and cause leaking. Attempting to replace a condenser pump is difficult. You should call an HVAC technician if you believe your condenser pump is broken.
When the refrigerant levels drop in your window AC, the cooling coils have to work harder to cool your home. Less heat will be removed from your home, causing the coils to struggle. Your window AC will operate less efficiently and require more electricity. You will notice your electric bill quickly rising.
