When your air conditioner is working 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 coolant.

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, repairing a leak will require professional air conditioning repair.

In most instances, you can stop 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 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 byproduct of the cooling process. Your air conditioner has two units, one outside and one inside. The indoor unit has an evaporator coil that cools warm air as it moves over it. Condensation occurs as the air cools, drips into a drain pan and drains out of your home through a condensate drain line.

Due to the condensation process, having water back up 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 happens:

Drain Line Is Clogged

Over time, mold can clog the condensate drain line. This can lead to water leaking inside your home. Our B & B Heating & Cooling pros can eliminate clogs and get water flowing again smoothly. Give us a call at 314-325-7552 for assistance.

Air Filter Is Dirty

We recommend changing 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 very cold and freeze it. As the coil defrosts, 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 broken condensate pump. Replacing your pan or pump requires a pro, so contact us at 314-325-7552 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner needs coolant to move heat. If your air conditioner was put in before 2011, it probably 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 develops one. They include:

  • Air that feels hotter or more humid than normal
  • 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 want an HVAC professional like B & B Heating & Cooling to fix an air conditioner coolant leak. In most situations, it might just be better to schedule air conditioning installation since Freon is costly. Manufacturing of this coolant was halted in 2020 due to its damaging effects on the ozone layer. As a result, just limited recycled quantities are available.
