Is your air conditioner leaking water? Find a solution fast

You bought your air conditioner unit to keep you free of the heat and humidity of the summer, but it doesn’t always keep the moisture out. In fact, air conditioners can leak for a variety of reasons, which is why you need to keep on top of your window unit or mini-split so that it remains in working order for the long term. If you find your air conditioner leaking water, it may not be broken, but it’s always a good idea to troubleshoot the issue in order to find a solution that keeps you cool and dry.

Weather conditions

One of the most common reasons for air conditioner leaks is simply the weather conditions outside your home. Often, high heat and humidity will cause a great deal of condensation on your machine, causing water to leak and drip down your walls. If your air conditioner is over-taxed, you may want to consider installing an additional unit to help take some of the pressure off of the single unit, but leaking from humidity may be unavoidable. Your air conditioner may also leak if the air outside is colder than the air inside your home. You can easily keep your unit from leaking by simply turning it off.

Installation problems

If weather conditions aren’t to blame for the leakage, improper installation probably is.

  • Make sure your drain hose is connected properly and flows into a proper drain, not just a hole in the ground. If the drain hose is backed up, it will cause water to leak from your machine.
  • Ensure that your air conditioner is level. Even if you have the unit snugly in the windowsill, it may not be level since your house can settle over time. In a non-level air conditioner, fluids may overflow and leak.
  • Check the seals around your unit to make sure that they are secure. Outside weather can have a big effect on moisture and condensation. If you don’t have proper seals, rain and humidity will leak in through your unit.
  • Finally, check to make sure that your vents are open. Closed vents will back up and cause pressure that could result in additional condensation and moisture.

Clogs and broken parts

With a properly installed machine, you shouldn’t experience any leaking. If you do, it could be a sign of broken parts or clogs in the unit. A broken pump can cause leaking. Although a broken pump probably means you’ll need to call a professional, you can test it yourself to see if that’s the problem. Pour water into your pump and see if it properly diverts the fluid; if not, it’s time to call in a pro. Otherwise, you may want to look for a clog. Dirty filters and drain hoses will easily back up water into the air conditioner. Simply clean out the working parts of your machine and you shouldn’t have to worry about leaking moisture anymore.
