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 home. In contrast, a coolant leak is dangerous for you and the environment. In either case, fixing a leak will require professional air conditioning repair.

In most instances, you can prevent your air conditioner from leaking by scheduling annual air conditioning maintenance. During your appointment, an HVAC technician will closely examine your system for problems and clean it. This service helps provide worry-free cooling and may even boost energy efficiency.

Why Won’t My Air Conditioning Stop 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 includes 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 home through a condensate drain line.

Due to the condensation process, having water back up is a common problem. We often receive 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 block the condensate drain line. This can lead to water leaking inside your home. Our Air Alliance Team pros can break up clogs and get water flowing again smoothly. Reach us at 636-206-4584 for help.

Air Filter Is Dirty

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
  • 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 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. Replacing your pan or pump requires a pro, so contact us at 636-206-4584 for help.

Why Is the Air Conditioning Leaking Freon?

Your air conditioner relies on coolant to transfer heat. If your air conditioner was put in before 2011, it probably has 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 feels warmer or more humid than usual
  • Bubbling or hissing noises near the air conditioner
  • Sweet smell near the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll need an HVAC professional like Air Alliance Team 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 halted in 2020 due to its harmful effects on the ozone layer. As a result, just reduced recycled quantities are available.
