Is a Leaking Air Conditioner Dangerous?

August 13, 2021

When your air conditioner is running properly, your home 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 home. On the other hand, a coolant leak is harmful to 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 yearly air conditioning maintenance. During your appointment, an HVAC technician will closely check your system for problems and clean it. This service helps ensure worry-free cooling and may even improve 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 result 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 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 often 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

Over time, mold can block the condensate drain line. This can result in water leaking inside your home. Our Marcos AC & Heating professionals can break up clogs and get water draining again smoothly. Reach us at 713-469-3357 for assistance.

Air Filter Needs to Be Changed

We recommend changing flat filters monthly 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 reduce airflow, make the coil very cold and cause it to freeze. As the coil defrosts, it can make the drain pan overflow. We recommend checking 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 malfunctioning condensate pump. Getting a new pan or pump requires a professional, so call us at 713-469-3357 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner needs coolant to transfer 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 good to know about air conditioner Freon leak symptoms in the event your system develops one. They include:

  • Air that seems hotter 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 professional like Marcos AC & Heating to repair an air conditioner coolant leak. In many situations, it may 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, only limited recycled quantities are available.
