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 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 harmful to you and the environment. In either case, fixing a leak will require professional air conditioning repair.

In most instances, you can stop your air conditioner from leaking by requesting annual air conditioning maintenance. During your appointment, an HVAC tech will closely examine your system for issues and clean it. This service helps provide worry-free performance 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 result of the cooling process. Your air conditioner has two systems, 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, flows into a drain pan and drains out of your home through a condensate drain line.

Because of the condensation process, having water leak is a common problem. We regularly get 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 clog the condensate drain line. This can result in water backing up inside your home. Our Lanz Furnace and Fireplace professionals can eliminate clogs and get water draining again smoothly. Reach us at 608-291-3606 for help.

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 critical for:

  • Indoor air quality
  • Energy efficiency
  • Decreasing breakdowns
  • Lengthening your air conditioner’s lifetime

A dirty air filter can restrict airflow, make the coil very cold and freeze it. As the coil defrosts, it can overwhelm the drain pan. We suggest checking your air filter if you haven’t changed it lately and your air conditioner is leaking water indoors.

If this doesn’t resolve the problem, your drain pan might be rusty or have a malfunctioning condensate pump. Getting a new pan or pump requires a professional, so call us at 608-291-3606 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner needs 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 create leaks.

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

  • Air that feels hotter or more humid than normal
  • Bubbling or hissing noises near the air conditioner
  • Sweet smell by the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll want an HVAC pro like Lanz Furnace and Fireplace to fix an air conditioner coolant leak. In many situations, it may just be better to schedule air conditioning installation since Freon is costly. Production of this coolant was stopped in 2020 because of its damaging effects on the ozone layer. As a result, only reduced recycled quantities are available.
