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 annoying but isn’t necessarily dangerous. 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 house. On the other hand, a coolant leak is dangerous for you and the environment. In either situation, repairing a leak will require skilled air conditioning repair.

In most cases, you can stop your air conditioner from leaking by scheduling annual air conditioning maintenance. During your appointment, an HVAC technician 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 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 drains out of your house through a condensate drain line.

Due to the condensation process, having water back up is a common problem. We often 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

As time passes, mold can block the condensate drain line. This can result in water backing up inside your house. Our PWA Heating & Cooling Inc professionals can eliminate clogs and get water draining again smoothly. Reach us at 815-410-1231 for assistance.

Air Filter Needs to Be Changed

We recommend replace flat filters monthly 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 extremely cold and cause it to freeze. As the coil defrosts, it can make the drain pan overflow. We recommend 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 broken condensate pump. Getting a new pan or pump requires a professional, so contact us at 815-410-1231 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner relies on coolant to move heat. If your air conditioner was installed before 2011, it likely has R-22 Freon. Over time, chemicals in Freon can eat through 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 feels warmer or more humid than normal
  • Bubbling or hissing noises near the air conditioner
  • Sweet odor by the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll need an HVAC professional like PWA Heating & Cooling Inc 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 damaging effects on the ozone layer. As a result, just reduced recycled quantities are available.
