Is a Leaking Air Conditioner Dangerous?

August 13, 2021

When your air conditioner is working 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 home. In contrast, a coolant leak is dangerous for you and the environment. In either situation, fixing a leak will require professional air conditioning repair.

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

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

Why Is My Air Conditioner Leaking Water?

Water is a natural byproduct of the cooling process. Your air conditioner has two units, one outside and one inside. The indoor unit includes 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 leak is a common problem. We regularly get 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 clog the condensate drain line. This can result in water leaking inside your home. Our American HVAC Inc pros can break up clogs and get water draining again smoothly. Reach us at 408-215-1018 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 life span

A dirty air filter can reduce airflow, make the coil extremely cold and cause it to freeze. As the coil melts, it can overwhelm the drain pan. We suggest checking your air filter if you haven’t changed it lately and your air conditioner is leaking water indoors.

If this doesn’t fix the problem, your drain pan may be rusty or have a broken condensate pump. Getting a new pan or pump requires a professional, so contact us at 408-215-1018 for help.

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 through metal and cause leaks.

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

  • Air that feels warmer or more humid than usual
  • Bubbling or hissing noises by the air conditioner
  • Sweet smell by the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll need an HVAC pro like American HVAC Inc to fix an air conditioner coolant leak. In many situations, it may just be better to schedule air conditioning installation since Freon is expensive. Manufacturing of this coolant was stopped in 2020 due to its damaging effects on the ozone layer. As a result, just limited recycled quantities are available.
