Is a Leaking Air Conditioner Dangerous?

August 13, 2021

When your air conditioner is working properly, your home will be cool and dry. A leaking air conditioner is annoying but isn’t necessarily dangerous. It depends on whether it’s leaking water or coolant.

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 harmful to you and the environment. In either case, repairing a leak will require skilled air conditioning repair.

In most cases, you can prevent your air conditioner from leaking by scheduling yearly air conditioning maintenance. During your appointment, an HVAC technician 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 stop 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 systems, one outside and one inside. The indoor unit includes an evaporator coil that cools warm air as it blows over it. Condensation occurs as the air cools, drips into a drain pan and goes 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 house. Our Home Comfort Heating & Air pros can break up clogs and get water draining again smoothly. Give us a call at 763-276-0617 for help.

Air Filter Is Dirty

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 overwhelm the drain pan. 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 issue, your drain pan may be rusty or have a broken condensate pump. Replacing your pan or pump requires a professional, so call us at 763-276-0617 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner relies on coolant to transfer heat. If your air conditioner was put in 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 case your system develops one. They include:

  • Air that seems warmer or more humid than usual
  • Bubbling or hissing noises by the air conditioner
  • Sweet odor by the air conditioner
  • Frozen evaporator coil

Freon is hazardous to your health if handled improperly, so you’ll need an HVAC professional like Home Comfort Heating & Air to fix an air conditioner coolant leak. In many instances, it might 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 reduced recycled quantities are available.
