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 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 dangerous for you and the environment. In either situation, fixing 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 tech will closely inspect your system for problems and clean it. This service helps provide worry-free cooling and might 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 has 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 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 occurs:

Drain Line Is Plugged

Over time, mold can block the condensate drain line. This can result in water leaking inside your house. Our GV Heating & Air professionals can eliminate clogs and get water flowing again smoothly. Give us a call at 763-535-2000 for help.

Air Filter Is Dirty

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
  • Extending your air conditioner’s life span

A dirty air filter can restrict airflow, make the coil very cold and freeze it. As the coil melts, it can overwhelm the drain pan. 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 fix the problem, your drain pan might be rusty or have a broken condensate pump. Replacing your pan or pump requires a professional, so call us at 763-535-2000 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner relies on coolant to transfer heat. If your air conditioner was installed 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 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 by the air conditioner
  • Frozen evaporator coil

Freon is hazardous to your health if handled improperly, so you’ll need an HVAC professional like GV Heating & Air to repair 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 halted in 2020 due to its damaging effects on the ozone layer. As a result, just limited recycled quantities are available.
