What would you do if your AC unit is leaking water and it’s not a drip? The first thing you should determine is where the leak is, we’ll deal with How To Fix Air Conditioner Leak. It could be an internal or external leakage.

Possible Causes of Air Conditioner Leak?

  • A defective or clogged condensate drain line
  • Seals are broken or missing due to an improperly installed wall or window units
  • A clogged evaporator drain
  • Weatherstripping around doors or windows has come loose
  • Leaky ductwork or poorly sealing registers also contribute to water leakage

Finding the source of the leak:

First things first! You need to determine where the AC unit that’s leaking is located at. If both indoor and outdoor units are affected then it might be caused by condensation from household humidity getting into equipment through poorly insulated pipes or joints, if only one of them is damaged then you can rest assured that there’s a bigger problem with other parts inside the system.

How to stop an indoor unit from leaking?

1. Check the drain hole in the base of the indoor unit (usually located on or near the bottom) and make sure it’s not clogged with dirt or lint, also empty any water present in this part of your unit.

2. Make sure there aren’t cracks on any parts of the pipeline connected to exterior equipment; seal them off if necessary.

3. If there is nothing wrong with these two things then you want to replace air filters before the situation gets worse.

How to stop the outdoor unit from leaking?

1. There is probably a hole or crack on any components of your pipe system so what you need to do is tighten up all loose joints and seal them if necessary; keep the holes clean and open for better results.

2. If your compressor hose has cracks and other forms of damage then it needs to be replaced as soon as possible because it doesn’t affect performance at this point but will probably result in more leakage later on.

3. Keep all outdoor units clean and free from dust.

If your home has central air conditioning then this will affect other areas as well so you must take care of these kinds of problems before they get too serious.

A step by step guide on How to Fix Air Conditioner Leak:

1. Go outside and turn off the unit’s power supply by pressing the circuit breaker.

2. Locate a panel on the front of your unit or a pad located on top of your roof where you will find a set of switches that control your system. Turn off the switch for your fan, motor, heat pump, or gas furnace that is causing the leak.

3. Walk around to the back of your unit and remove a few screws that attach a grill or other cover from one of the air intake vents on your unit.

4. Inspect the fan to see if it’s dusty or covered with leaves, grass clippings, or other debris which could be preventing it from turning smoothly. Clean the fan and surrounding area with your garden hose or power washer to prevent dirt or debris from entering the system.

5. Look through the grill opening and turn on your unit by pressing and holding a large round button which is located near the front of it. Watch for water coming out of any openings at its base where you could leak.

6. Run your hand along with the coils on the back of your unit and look for any that are wet to check for a current leak. Coil leaks can be more difficult to locate since water on these metal surfaces will blend in with condensation.

7. Look over the front grill opening on your compressor area and watch for any water coming from the area around the compressor’s valves, a sign that a refrigerant leak has occurred.

8. Look under your air conditioner and check for a large amount of water pooling up on the exterior which could indicate a drain line problem or condensate pump issue. You can tell if you have a condensate pump by finding a small, cylindrical, and semi-transparent tube that should be located at the lowest point of your air conditioner’s tubing.

9. Locate an access panel on top or behind your unit to make repairs which can usually be accessed from the outside. Make sure not to block any vents or grills with your access panel, instead use a screen or additional grill to allow airflow.

10. Install an access panel by taking out the screws that are holding in your current one. Insert the new panel with screws to make sure it fits snuggly and lies flat against your unit’s exterior to prevent rain from entering behind it.

11. Replace grills, vents, and switches to their original positions by taking out the screws that hold them in place.

12. Turn on your unit’s power supply switch if you haven’t done so already and check for leaks or dampness around all interior areas of your unit again. Make sure the fan turns properly and that condensation water is draining appropriately.

13. Turn your circuit breaker back on to return power to the unit and go inside to check the temperature of your home. If it is warmer than before, you have successfully fixed your air conditioner leak!

14. Wash out grills and panels with a hose or power washer if they are still dirty after making repairs.

15. Turn the unit’s power supply switch back off and return it to your access panel. Unscrew and remove it so you can inspect your repair work for any problems.

16. Clean out any holes or gaps around the edges of your new installation where water could seep through to prevent further leaks in the future. You can do this by using a caulk gun to apply a generous bead of caulking around the perimeter of your new access panel.

17. Put screws through your new access panel to hold it firmly in place and seal off any gaps between the edges with caulk again, if necessary.

18. Turn on your unit’s power supply switch and press the button that starts it up to check for any leaks.

19. After your unit has been running and checking for leaks, turn off its power supply switch and wait a few minutes before sliding an access panel tightly into place to finish the repair process.

20. Turn on your unit’s power supply switch so you can use it again as usual! Now that you’ve learned how to fix leaks, you can now enjoy your well-working air conditioner!
