Is a Leaking Air Conditioner Dangerous?

August 13, 2021

When your air conditioner is working 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 refrigerant.

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

In most instances, you can stop your air conditioner from leaking by scheduling annual air conditioning maintenance. During your appointment, an HVAC tech will closely check your system for problems and clean it. This service helps ensure worry-free cooling and may 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 result of air conditioning. 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 goes out of your house through a condensate drain line.

Due to 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

As time passes, mold can clog the condensate drain line. This can result in water leaking inside your home. Our Walter's-Eaton's Electric, Plumbing, Heating & AC pros can break up clogs and get water draining again smoothly. Reach us at 715-318-6728 for help.

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
  • Decreasing breakdowns
  • Lengthening your air conditioner’s life span

A dirty air filter can reduce airflow, make the coil extremely 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 may be rusty or have a broken condensate pump. Getting a new pan or pump requires a professional, so call us at 715-318-6728 for assistance.

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. As time passes, chemicals in Freon can eat away at metal and cause leaks.

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

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

Freon is hazardous to your health if handled improperly, so you’ll want an HVAC professional like Walter's-Eaton's Electric, Plumbing, Heating & AC to fix an air conditioner coolant leak. In many situations, it may just be better to request air conditioning installation since Freon is expensive. Production of this coolant was stopped in 2020 due to its damaging effects on the ozone layer. As a result, only limited recycled quantities are available.
