When your air conditioner is running 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 bad but can cause a lot of damage to your home. On the other hand, a coolant leak is dangerous for you and the environment. In either situation, repairing a leak will require skilled 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 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 moves over it. Condensation forms as the air cools, flows into a drain pan and goes out of your home through a condensate drain line.

Because of 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

As time passes, mold can block the condensate drain line. This can lead to water leaking inside your home. Our Controlled Comfort HVAC pros can break up clogs and get water flowing again smoothly. Reach us at 224-412-8308 for help.

Air Filter Is Dirty

We recommend replace flat filters monthly 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 lifetime

A dirty air filter can reduce airflow, make the coil extremely cold and cause it to freeze. As the coil melts, it can overwhelm the drain pan. We recommend 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 may be rusty or have a broken condensate pump. Getting a new pan or pump requires a pro, so call us at 224-412-8308 for assistance.

Why Won’t My Air Conditioning Stop Leaking Freon?

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

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

  • Air that feels warmer or more humid than normal
  • Bubbling or hissing sounds near the air conditioner
  • Sweet odor near the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll want an HVAC pro like Controlled Comfort HVAC to fix an air conditioner coolant leak. In most situations, it may just be better to request air conditioning installation since Freon is costly. Production of this coolant was stopped in 2020 due to its harmful effects on the ozone layer. As a result, just reduced recycled quantities are available.
