Is a Leaking Air Conditioner Dangerous?

August 13, 2021

When your air conditioner is running 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 refrigerant.

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 dangerous for you and the environment. In either situation, fixing a leak will require skilled 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 tech will closely check your system for issues and clean it. This service helps ensure worry-free cooling and might even improve energy efficiency.

Find out 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 air conditioning. 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 occurs as the air cools, flows into a drain pan and drains 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 Plugged

As time passes, mold can block the condensate drain line. This can result in water leaking inside your home. Our Air Alliance Team pros can break up clogs and get water flowing again smoothly. Reach us at 636-206-4250 for help.

Air Filter Is Dirty

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

Replacing your air filter is critical 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 very cold and cause it to freeze. 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 fix the issue, your drain pan might be rusty or have a malfunctioning condensate pump. Replacing your pan or pump requires a professional, so call us at 636-206-4250 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner relies on 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 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 sounds near the air conditioner
  • Sweet smell near the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll need an HVAC professional like Air Alliance Team to fix an air conditioner coolant leak. In most instances, it might just be better to request air conditioning installation since Freon is expensive. Manufacturing of this coolant was halted in 2020 because of its harmful effects on the ozone layer. As a result, just limited recycled quantities are available.
