Is a Leaking Air Conditioner Dangerous?

August 13, 2021

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 house. On the other hand, a coolant leak is dangerous for you and the environment. In either case, fixing a leak will require professional air conditioning repair.

In most cases, you can stop 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 provide worry-free performance and may even improve energy efficiency.

Find out why your air conditioner is leaking and how you can stop it from happening in the future.

Why Is My Air Conditioner Leaking Water?

Water is a natural byproduct of the cooling process. 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 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 Clogged

Over time, mold can clog the condensate drain line. This can result in water leaking inside your home. Our Paso Robles Heating and Air professionals can eliminate clogs and get water draining again smoothly. Give us a call at 805-203-8667 for assistance.

Air Filter Needs to Be Changed

We recommend changing 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 restrict airflow, make the coil very cold and freeze it. As the coil defrosts, it can overwhelm the drain pan. We suggest inspecting your air filter if you haven’t replaced 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 805-203-8667 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner uses coolant to transfer heat. If your air conditioner was installed before 2011, it likely has R-22 Freon. As time passes, chemicals in Freon can eat through 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 warmer or more humid than normal
  • Bubbling or hissing noises 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 need an HVAC professional like Paso Robles Heating and Air to fix an air conditioner coolant leak. In most instances, it might just be better to schedule air conditioning installation since Freon is expensive. Production of this coolant was halted in 2020 because of its harmful effects on the ozone layer. As a result, just reduced recycled quantities are available.
