Uncover the ‘Causes of Indoor Air Conditioner Leaking’ with our detailed guide. Stay informed and prevent costly AC damage today!

If you’ve observed water seeping from your air conditioner, you’re not the only one. This is a common issue that many individuals deal with. In most cases, the water comes from the coils in the back of the unit. Many times, this is simply due to condensation. There are a few additional reasons for an air conditioner leaking inside your house. These eight causes could occur.

Why My AC is Leaking Water

1. Condensate Drain Is Blocked – When your air conditioner runs, the coils in the back of the unit get very cold. This causes water to condense on the coils. The water then drips into a drain pan and is drained out of your home through a pipe. If this pipe becomes blocked, the water will return to your home. If you suspect your condensate drain is blocked, contact a professional for assistance.

2. Drain Line Is Disconnected – Most air conditioners have a drain line from the back of the unit to the outside of your home. If this drain line becomes disconnected, water will leak out of the unit and into your home. Also, if the drain line is not installed correctly, it could become disconnected. Several factors can cause the drain line to become disconnected, including animals chewing on the line or a severe storm.

3. Air Filter Is Dirty – The air filter in your air conditioner may limit airflow if it is unclean. This may lead to the device leaking water and the coils freezing. It’s essential to check your air filter regularly and replace it when it’s dirty. According to ac repair Magnolia TX, if you have a disposable air filter, you should replace it every 30 days. If your air filter is washable, you should change it every two weeks.

4. Condensate Pump Isn’t Working – If your air conditioner has a condensate pump, it helps to remove water from the unit. If the condensate pump isn’t working, the unit will leak water. Many times, a blown a fuse is all that’s wrong. An AC repair Cypress TX study shows that you can check the fuse and replace it if necessary. It is a simple repair that you can do yourself.

5. Low Refrigerant Level – If your air conditioner is low on refrigerant, it can cause the unit to leak water. The air in your home is cooled in part by the refrigerant. If there’s a leak in the refrigerant line, it can cause the unit to lose refrigerant. A professional must repair the leak and recharge the unit with refrigerant.

6. Frozen Coils – If the coils in your air conditioner freeze, it can cause the unit to leak water. There are several reasons why the coils might freeze. One reason is that the air filter is dirty and restricts airflow. Another reason is that the thermostat is set too low. If you suspect the coils are frozen, you should turn off the unit and call a professional for assistance.

7. Damaged Drip Pan – The drip pan is located behind the appliance’s coils. To catch the water that drips from the coils is its intended use. If the drip pan becomes damaged, it can cause water to leak from the unit. You will typically need to replace the drip pan. Purchase a drip pan that is the proper size and form when replacing the old one.

8. Outdoor Temperature Is Too Cold to Run AC – Sometimes, the outdoor temperature can be too cold to run your air conditioner. When this happens, water can condense on the coils and drip into the drip pan. If the outdoor temperature is below 60 degrees Fahrenheit, it’s best not to run your air conditioner. Also, if you have a heat pump, it can cause the unit to leak water if the outdoor temperature is below freezing.

How to Fix AC Leaking Water Inside

Check the coils in the back of the air conditioner if you notice that it is dripping water into your house. These are usually the cause of the problem. If they’re dirty, they can cause the unit to leak water. Dry them off after wiping them down with a moist cloth. Additionally, ensure sure the drain pan isn’t overflowing with water by checking it. If so, remove everything and clean it out.

Why My AC Leak When I Turn It Off

If your air conditioner leaks water when you turn it off, it’s likely because the coils are frozen. When the coils freeze, they can cause the unit to leak water. The best way to thaw the coils is to turn off the unit and let it sit for a few hours. Once the coils have thawed out, you can turn the unit back on.

The essential thing to follow is never to ignore an AC unit leaking. If you do, it can cause severe damage to your home. Be sure to practice air conditioning maintenance and have a professional check your unit regularly. Doing so can avoid many potential causes of an AC leak.
