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 dangerous but can cause a lot of damage to your house. In contrast, a coolant leak is dangerous for you and the environment. In either situation, repairing a leak will require skilled air conditioning repair.

In most cases, you can prevent your air conditioner from leaking by scheduling annual air conditioning maintenance. During your appointment, an HVAC technician will closely inspect your system for problems and clean it. This service helps provide worry-free cooling and may even improve 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 air conditioning. Your air conditioner has two units, one outside and one inside. The indoor unit has an evaporator coil that cools warm air as it blows over it. Condensation occurs 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 occurs:

Drain Line Is Clogged

As time passes, mold can block the condensate drain line. This can lead to water leaking inside your home. Our Kowalski Heating, Cooling & Plumbing professionals can break up clogs and get water draining again smoothly. Reach us at 724-370-0141 for help.

Air Filter Needs to Be Changed

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

Replacing your air filter is critical for:

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

A dirty air filter can reduce airflow, make the coil very cold and freeze it. As the coil melts, it can make the drain pan overflow. We recommend 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 problem, your drain pan may be rusty or have a malfunctioning condensate pump. Getting a new pan or pump requires a professional, so contact us at 724-370-0141 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner needs coolant to transfer heat. If your air conditioner was installed before 2011, it likely has 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 usual
  • Bubbling or hissing noises by the air conditioner
  • Sweet odor by the air conditioner
  • Frozen evaporator coil

Freon is hazardous to your health if handled improperly, so you’ll need an HVAC pro like Kowalski Heating, Cooling & Plumbing to fix an air conditioner coolant leak. In many situations, it may just be better to request air conditioning installation since Freon is costly. Manufacturing of this coolant was stopped in 2020 due to its damaging effects on the ozone layer. As a result, just reduced recycled quantities are available.
