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 annoying 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 harmful to you and the environment. In either situation, fixing a leak will require professional air conditioning repair.

In most instances, you can stop your air conditioner from leaking by scheduling annual air conditioning maintenance. During your appointment, an HVAC technician will closely check your system for issues and clean it. This service helps ensure worry-free performance and might 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 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, drips into a drain pan and drains out of your house through a condensate drain line.

Due to 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 occurs:

Drain Line Is Plugged

Over time, mold can block the condensate drain line. This can lead to water backing up inside your house. Our H&C Heating and Cooling professionals can eliminate clogs and get water flowing again smoothly. Give us a call at 301-960-3247 for assistance.

Air Filter Needs to Be Changed

We recommend changing flat filters monthly 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 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 replaced 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 broken condensate pump. Getting a new pan or pump requires a pro, so contact us at 301-960-3247 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner uses coolant to move heat. If your air conditioner was installed before 2011, it probably has R-22 Freon. As time passes, chemicals in Freon can eat through metal and cause leaks.

It’s good 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 sounds 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 professional like H&C Heating and Cooling to fix an air conditioner coolant leak. In most situations, it may just be better to request air conditioning installation since Freon is costly. Manufacturing of this coolant was halted in 2020 because of its harmful effects on the ozone layer. As a result, only limited recycled quantities are available.
