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 refrigerant.

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

In most cases, you can stop your air conditioner from leaking by requesting 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 cooling and might even improve energy efficiency.

Find out 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 units, one outside and one inside. The indoor unit has 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 house through a condensate drain line.

Due to the condensation process, having water leak 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 Clogged

As time passes, mold can block the condensate drain line. This can lead to water backing up inside your house. Our Colvin's Heating and Cooling pros can eliminate clogs and get water flowing again smoothly. Give us a call at 816-379-3918 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
  • Reducing breakdowns
  • Extending your air conditioner’s life span

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 checking 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 may be rusty or have a malfunctioning condensate pump. Getting a new pan or pump requires a pro, so contact us at 816-379-3918 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner needs coolant to transfer heat. If your air conditioner was put in before 2011, it likely has R-22 Freon. Over time, chemicals in Freon can eat away at metal and create 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 normal
  • Bubbling or hissing noises by the air conditioner
  • Sweet smell by the air conditioner
  • Frozen evaporator coil

Freon is hazardous to your health if handled improperly, so you’ll need an HVAC pro like Colvin's Heating and Cooling to repair an air conditioner coolant leak. In most situations, it might just be better to request air conditioning installation since Freon is costly. Production of this coolant was halted in 2020 because of its harmful effects on the ozone layer. As a result, only reduced recycled quantities are available.
