Is a Leaking Air Conditioner Dangerous?

August 13, 2021

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 refrigerant.

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

In most instances, you can prevent your air conditioner from leaking by scheduling yearly air conditioning maintenance. During your appointment, an HVAC tech will closely examine your system for problems and clean it. This service helps ensure worry-free cooling and may even improve 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 often get 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 clog the condensate drain line. This can lead to water backing up inside your house. Our Strine's Heating & Air Conditioning pros can break up clogs and get water draining again smoothly. Give us a call at 717-383-4479 for help.

Air Filter Needs to Be Changed

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
  • Extending your air conditioner’s lifetime

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

If this doesn’t resolve 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 717-383-4479 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner uses coolant to transfer heat. If your air conditioner was installed before 2011, it likely has R-22 Freon. As time passes, 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 hotter or more humid than usual
  • Bubbling or hissing sounds by the air conditioner
  • Sweet smell near the air conditioner
  • Frozen evaporator coil

Freon is hazardous to your health if handled improperly, so you’ll want an HVAC professional like Strine's Heating & Air Conditioning to repair an air conditioner coolant leak. In most instances, it may just be better to request air conditioning installation since Freon is costly. Manufacturing of this coolant was stopped in 2020 because of its damaging effects on the ozone layer. As a result, only reduced recycled quantities are available.
