Is a Leaking Air Conditioner Dangerous?

August 13, 2021

When your air conditioner is running 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 refrigerant.

Water leaking from your air conditioner isn’t bad 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 case, repairing 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 examine your system for problems and clean it. This service helps provide worry-free cooling and might even improve energy efficiency.

Find out 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 air conditioning. Your air conditioner has two units, one outside and one inside. The indoor unit includes an evaporator coil that cools warm air as it blows over it. Condensation forms as the air cools, drips into a drain pan and goes out of your home through a condensate drain line.

Because of the condensation process, having water back up is a common problem. We often get calls about an air conditioner leaking water inside or an air conditioner leaking water outside. Here’s why it occurs:

Drain Line Is Clogged

Over time, mold can clog the condensate drain line. This can result in water backing up inside your home. Our M & S Heating & Air LLC pros can eliminate clogs and get water draining again smoothly. Reach us at 301-363-4699 for assistance.

Air Filter Needs to Be Changed

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
  • Decreasing breakdowns
  • Lengthening 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 resolve the issue, your drain pan may be rusty or have a malfunctioning condensate pump. Replacing your pan or pump requires a professional, so call us at 301-363-4699 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 likely has R-22 Freon. Over time, chemicals in Freon can eat away at metal and cause leaks.

It’s good to know about air conditioner Freon leak symptoms in the event your system has one. They include:

  • Air that seems warmer or more humid than usual
  • Bubbling or hissing sounds 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 need an HVAC pro like M & S Heating & Air LLC to repair an air conditioner coolant leak. In most instances, it might just be better to request air conditioning installation since Freon is costly. Manufacturing of this coolant was stopped in 2020 due to its damaging effects on the ozone layer. As a result, just limited recycled quantities are available.
