Why Is Your AC Indoor Unit Leaking?

Summers in Canada are not unbearable but there is still a need to turn the AC on during the mid-summer months. At times like these, HVAC issues can be frustrating and inconvenient.

Imagine coming back to your home in the summer and not being able to turn on your AC just because it is leaking water. Everyone wants to enjoy some cooling and relax for a while to prepare themselves for the next tasks. However, any problem with your air conditioner can be quite frustrating.

Your indoor AC unit dripping down water can be a very unsettling sight. You might have to mop your floor repeatedly or keep up a bucket from where the water is leaking.

All in all, it doesn’t give a good outlook, especially when guests are visiting you. Therefore, it is better to turn off the unit immediately and contact an HVAC contractor to solve this issue.

Maintaining your AC is important. There might be many reasons why your indoor AC unit may be leaking water. We will mention some common reasons below to help you identify the problem in your AC and take the necessary steps to solve that problem. Continue reading to find out the most common causes of indoor air conditioner leaks and what their immediate fixes are.

Blocked Drain Line

The purpose of a drain line is to remove the access condensation from the air conditioner. If there is any problem with the drain line of your AC or it is blocked, it won’t be able to remove the excess condensation.

Therefore, the indoor unit will collect moisture. This moisture also contains dirt and debris, which causes blockage in the condensate drain line. Eventually, this will start collecting water in the unit, which will lead to the spill out of the drain pan right inside your house.

Maintaining your AC unit and unplugging the condensate drain line is necessary to prevent the collection of moisture in your indoor unit. Although you can also take care of your AC’s drain line on your own by scrapping the line to remove any gunk it is advised that you hire an HVAC contractor with a special pump or vacuum to make sure the drain line is properly cleaned.

The Air Filters Might Be Dirty

Did you know that you should change your air filter every day? If you don’t, you might be putting too much load on your AC and making it work harder. The air filters of an air conditioner have to face dirt every day while blowing out cool air to your room.

After some time, these filters become clogged due to dirt and dust, which blocks the flow of air to the evaporator coil. This frozen coil melts, and the excess water can cause your indoor unit to overflow.

Therefore, you should keep a close eye on your air filter and change it or clean it every month or two. It is quite easy to clean your air filter on your own, but if you don’t know how to clean them, you can always call a professional to clean them for you.

Other Common Reasons Your AC May Leak Water

  • Broken condensate pump
  • Broken float switch
  • Disconnected drain line
  • Condensation build-up
  • Frozen evaporator coils
  • Low refrigerant levels
  • Improper installation of AC

Take Away

Now that you know all the possible reasons that might lead your AC to leak water, it is necessary to find out your reason and perform the necessary solution for it. It is good to conduct AC cleaning on your own after a few days. However, if you are not an expert it is always advisable to call a professional air conditioner service company to solve any problem with your air conditioner.
