When your air conditioner is working properly, your house will be cool and dry. A leaking air conditioner is annoying but isn’t necessarily harmful. 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 skilled air conditioning repair.

In most instances, you can prevent your air conditioner from leaking by requesting annual air conditioning maintenance. During your appointment, an HVAC tech will closely check your system for issues and clean it. This service helps ensure worry-free performance and might even boost energy efficiency.

Learn more about why your air conditioner is leaking and how you can prevent it from happening in the future.

Why Is My Air Conditioner Leaking Water?

Water is a natural byproduct of air conditioning. Your air conditioner has two units, one outside and one inside. The indoor unit includes an evaporator coil that cools warm air as it moves over it. Condensation forms as the air cools, drips 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

As time passes, mold can clog the condensate drain line. This can lead to water leaking inside your house. Our Olde Towne Heating & Air professionals can break up clogs and get water draining again smoothly. Give us a call at 843-485-0967 for help.

Air Filter Needs to Be Changed

We recommend replace flat filters once a month and pleated filters every three months.

Replacing your air filter is critical for:

  • Indoor air quality
  • Energy efficiency
  • Reducing breakdowns
  • Lengthening your air conditioner’s life span

A dirty air filter can reduce airflow, make the coil very cold and cause it to freeze. As the coil defrosts, it can make the drain pan overflow. We suggest inspecting your air filter if you haven’t changed 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 malfunctioning condensate pump. Getting a new pan or pump requires a professional, so call us at 843-485-0967 for assistance.

Why Is My Air Conditioner Leaking Freon?

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

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

  • Air that seems warmer or more humid than usual
  • 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 need an HVAC pro like Olde Towne Heating & Air to fix an air conditioner coolant leak. In most instances, it might just be better to request air conditioning installation since Freon is costly. Manufacturing of this coolant was stopped in 2020 due to its harmful effects on the ozone layer. As a result, only reduced recycled quantities are available.
