When your air conditioner is working properly, your house will be cool and dry. A leaking air conditioner is frustrating 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 home. In contrast, a coolant leak is harmful to you and the environment. In either situation, fixing a leak will require professional 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 performance 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 Won’t My Air Conditioning Stop Leaking Water?

Water is a natural byproduct of air conditioning. Your air conditioner has two systems, 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 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 occurs:

Drain Line Is Plugged

Over time, mold can clog the condensate drain line. This can lead to water leaking inside your home. Our May's Heating & Air professionals can eliminate clogs and get water flowing again smoothly. Reach us at 301-690-0397 for help.

Air Filter Is Dirty

We recommend replace flat filters monthly and pleated filters every three months.

Replacing your air filter is crucial for:

  • Indoor air quality
  • Energy efficiency
  • Reducing breakdowns
  • Extending 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 make the drain pan overflow. We suggest inspecting your air filter if you haven’t replaced it lately and your air conditioner is leaking water indoors.

If this doesn’t fix the problem, your drain pan might be rusty or have a broken condensate pump. Replacing your pan or pump requires a pro, so call us at 301-690-0397 for help.

Why Does My AC Unit Leak Freon?

Your air conditioner uses coolant to move heat. If your air conditioner was installed before 2011, it likely uses R-22 Freon. As time passes, chemicals in Freon can eat through metal and cause leaks.

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

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

Freon is bad for your health if handled improperly, so you’ll need an HVAC professional like May's Heating & Air to fix an air conditioner coolant leak. In many situations, it may just be better to schedule 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 limited recycled quantities are available.
