Is a Leaking Air Conditioner Dangerous?

August 13, 2021

When your air conditioner is working properly, your home will be cool and dry. A leaking air conditioner is frustrating but isn’t necessarily dangerous. 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. On the other hand, a coolant leak is harmful to you and the environment. In either case, repairing a leak will require professional air conditioning repair.

In most cases, you can prevent your air conditioner from leaking by requesting yearly 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 systems, one outside and one inside. The indoor unit includes an evaporator coil that cools warm air as it blows 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 regularly receive calls about an air conditioner leaking water inside or an air conditioner leaking water outside. Here’s why it happens:

Drain Line Is Clogged

As time passes, mold can block the condensate drain line. This can lead to water leaking inside your house. Our Three Rivers Heating & Cooling professionals can break up clogs and get water flowing again smoothly. Give us a call at 503-213-4433 for assistance.

Air Filter Is Dirty

We recommend changing flat filters once a month and pleated filters every three months.

Replacing your air filter is crucial for:

  • Indoor air quality
  • Energy efficiency
  • Decreasing breakdowns
  • Lengthening your air conditioner’s lifetime

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

If this doesn’t resolve the issue, your drain pan might be rusty or have a broken condensate pump. Getting a new pan or pump requires a pro, so contact us at 503-213-4433 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner uses coolant to transfer heat. If your air conditioner was put in before 2011, it likely uses R-22 Freon. Over time, chemicals in Freon can eat away at metal and create leaks.

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

  • Air that seems warmer or more humid than usual
  • Bubbling or hissing noises by 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 Three Rivers Heating & Cooling to fix an air conditioner coolant leak. In many instances, it may just be better to schedule air conditioning installation since Freon is expensive. Production 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.
