An air conditioner is a very important appliance to have in the summertime, but when it starts leaking water inside your house, it can be a major inconvenience. To avoid extensive water damage and the risk of electric shock, turn off your air conditioner. Next, call an HVAC contractor like DeZiel Heating & AC.

Why Is My Air Conditioner Leaking Water Inside My House

In this article, we will go over some of the possible reasons why your air conditioner might be leaking water. It’s important to understand why this happens so you can take steps to prevent water damage and keep your air conditioner running efficiently.

Why Does Water Form in Your Air Conditioner’s Indoor Unit?

In a nutshell, water forms in the indoor unit of your air conditioner because warm, moist air is being condensed and cooled. This process creates condensation, which can drip down into the outdoor unit if not properly drained. The condensation is supposed to collect in a drain pan and move on to a condensate drain pipe that goes out of your home or into your plumbing system.

Clogged Condensate Drain Line or Rusted Pan

A potential cause of water in your air conditioner is a clogged condensate drain line or a rusted condensate pan. Your drain line can be clogged by insects, dirt or even a dirty evaporator coil. If the water can’t move through the drain pipe or the pan fills up with water, it will start to leak out.

To resolve this problem, you will need to clean the drain line or replace the pan. If the clog is farther down in the line, you might need to call a professional to clear it for you.

Dirty or Clogged Air Filter

One of the most common reasons for water formation in an air conditioner is a dirty or clogged filter. When the filter gets dirty, it can’t do its job of intercepting dust and dirt from the air. This causes the air conditioner to work harder, which leads to more condensation and, ultimately, water dripping inside your house.

To prevent this problem, make sure to change your air filter regularly. A dirty air filter can also cause your air conditioner to run inefficiently and increase your energy bills.

Wrongly Installed Condensate Trap

Another possible cause of water in your air conditioner is a wrongly installed condensate trap. This can happen if the contractor who instals your air conditioner doesn’t do it correctly or if the part becomes dislodged over time. If the trap isn’t working properly, it will allow water to flow back into the indoor unit, which can cause water damage.

If you think your condensate trap might not be working well, you can check it yourself by pouring a bucket of water into the drain pipe. If the water flows out the other end, then the trap is working correctly. If it doesn’t, you might need to call a professional to fix it.

Frozen Evaporator Coil

Water in your air conditioner can also be due to a frozen evaporator coil. When the coil becomes frozen, it can’t do its job of cooling the air, which leads to more condensation and, ultimately, water dripping out of the unit.

A frozen evaporator coil may occur as a result of;

  • Low refrigerant
  • Dirty air filter
  • Airflow problem

To prevent your evaporator coil from freezing, you need to make sure it’s properly insulated and that the refrigerant levels are correct. You should also make sure your air filter is clean and that there is enough airflow through the unit. If you’re having trouble fixing the problem yourself, you might need to call a professional.

Other Reasons Why Your AC May Leak Water

There are other reasons why your AC might leak water, such as a malfunctioning compressor or a problem with the wiring. If you’re experiencing water leaks and you can’t seem to find the source, it’s best to call a professional to take a look at your unit. They will be able to diagnose the problem and help you get your air conditioner back up and running.

So, now that you know some of the reasons why your air conditioner might be leaking water, what do you do? The best thing to do is to call a professional. They will be able to find the cause of the problem and help you fix it. And, if it’s something that you can fix yourself, they will be able to guide you through the process.
