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 refrigerant.

Water leaking from your air conditioner isn’t bad but can cause a lot of damage to your house. In contrast, a coolant leak is dangerous for you and the environment. In either case, repairing a leak will require professional air conditioning repair.

In most cases, 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 improve energy efficiency.

Why Does My AC Unit Leak Water?

Water is a natural result of the cooling process. Your air conditioner has two systems, one outside and one inside. The indoor unit has an evaporator coil that cools warm air as it blows over it. Condensation forms as the air cools, flows 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 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

As time passes, mold can clog the condensate drain line. This can result in water leaking inside your house. Our AW Heating & Air Conditioning professionals can break up clogs and get water draining again smoothly. Reach us at 402-438-7992 for assistance.

Air Filter Is Dirty

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
  • Decreasing breakdowns
  • Lengthening your air conditioner’s lifetime

A dirty air filter can reduce airflow, make the coil extremely 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 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 malfunctioning condensate pump. Getting a new pan or pump requires a professional, so contact us at 402-438-7992 for help.

Why Does My AC Unit Leak Freon?

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

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

  • Air that seems warmer or more humid than usual
  • 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 pro like AW Heating & Air Conditioning to repair an air conditioner coolant leak. In most instances, it may just be better to schedule air conditioning installation since Freon is costly. Production of this coolant was stopped in 2020 because of its damaging effects on the ozone layer. As a result, only limited recycled quantities are available.
