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 dangerous but can cause a lot of damage to your home. On the other hand, a coolant leak is harmful to you and the environment. In either case, fixing a leak will require professional air conditioning repair.

In most cases, you can prevent your air conditioner from leaking by scheduling yearly 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 performance and might even boost 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 moves over it. Condensation forms as the air cools, drips into a drain pan and drains out of your home through a condensate drain line.

Because of 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 happens:

Drain Line Is Clogged

Over time, mold can clog the condensate drain line. This can lead to water leaking inside your house. Our Giordanos Heating and Air Conditioning pros can eliminate clogs and get water draining again smoothly. Reach us at 203-772-8319 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 crucial for:

  • Indoor air quality
  • Energy efficiency
  • Decreasing breakdowns
  • Extending your air conditioner’s life span

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 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 might be rusty or have a broken condensate pump. Replacing your pan or pump requires a professional, so call us at 203-772-8319 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner uses coolant to move heat. If your air conditioner was put in before 2011, it probably has R-22 Freon. Over time, chemicals in Freon can eat away at 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 feels hotter or more humid than normal
  • Bubbling or hissing noises near the air conditioner
  • Sweet odor by the air conditioner
  • Frozen evaporator coil

Freon is hazardous to your health if handled improperly, so you’ll want an HVAC professional like Giordanos Heating and Air Conditioning to fix an air conditioner coolant leak. In many situations, it may just be better to request air conditioning installation since Freon is expensive. Manufacturing 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.
