When your air conditioner is running properly, your house will be cool and dry. A leaking air conditioner is frustrating but isn’t necessarily harmful. It depends on whether it’s leaking water or coolant.

Water leaking from your air conditioner isn’t bad but can cause a lot of damage to your house. In contrast, a coolant leak is dangerous for you and the environment. In either case, fixing a leak will require professional air conditioning repair.

In most instances, you can stop your air conditioner from leaking by requesting annual air conditioning maintenance. During your appointment, an HVAC technician will closely inspect your system for problems and clean it. This service helps ensure worry-free performance and may even boost energy efficiency.

Learn more about why your air conditioner is leaking and how you can prevent it from happening in the future.

Why Is My Air Conditioner Leaking Water?

Water is a natural result of the cooling process. Your air conditioner has two units, one outside and one inside. The indoor unit has an evaporator coil that cools warm air as it moves over it. Condensation forms as the air cools, drips into a drain pan and goes out of your home through a condensate drain line.

Because of the condensation process, having water back up is a common problem. We often get calls about an air conditioner leaking water inside or an air conditioner leaking water outside. Here’s why it occurs:

Drain Line Is Clogged

Over time, mold can clog the condensate drain line. This can result in water backing up inside your house. Our Morgner Inc. Air Conditioning & Heating professionals can break up clogs and get water flowing again smoothly. Reach us at 314-262-4541 for assistance.

Air Filter Needs to Be Changed

We recommend changing flat filters monthly and pleated filters every three months.

Replacing your air filter is crucial for:

  • Indoor air quality
  • Energy efficiency
  • Reducing breakdowns
  • Lengthening your air conditioner’s life span

A dirty air filter can restrict airflow, make the coil extremely cold and freeze it. As the coil defrosts, it can make the drain pan overflow. We suggest checking your air filter if you haven’t replaced it lately and your air conditioner is leaking water indoors.

If this doesn’t fix the issue, your drain pan may be rusty or have a malfunctioning condensate pump. Replacing your pan or pump requires a pro, so contact us at 314-262-4541 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner relies on coolant to move heat. If your air conditioner was installed before 2011, it likely uses R-22 Freon. Over time, chemicals in Freon can eat through metal and create leaks.

It’s important to know about air conditioner Freon leak symptoms in case your system develops one. They include:

  • Air that seems warmer or more humid than normal
  • Bubbling or hissing noises near the air conditioner
  • Sweet odor by the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll need an HVAC professional like Morgner Inc. Air Conditioning & Heating to fix an air conditioner coolant leak. In most situations, it may just be better to schedule air conditioning installation since Freon is costly. Manufacturing of this coolant was stopped in 2020 because of its harmful effects on the ozone layer. As a result, only limited recycled quantities are available.
