When your air conditioner is working 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 coolant.

Water leaking from your air conditioner isn’t bad but can cause a lot of damage to your home. In contrast, a coolant leak is harmful to you and the environment. In either case, fixing 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 inspect your system for issues and clean it. This service helps ensure worry-free cooling and might even improve energy efficiency.

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

Why Does My AC Unit Leak Water?

Water is a natural byproduct 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 moves over it. Condensation occurs 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 back up 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 happens:

Drain Line Is Plugged

Over time, mold can block the condensate drain line. This can result in water leaking inside your home. Our B & B Heating & Cooling pros can eliminate clogs and get water flowing again smoothly. Give us a call at 314-325-7552 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
  • Lengthening your air conditioner’s life span

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 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 issue, your drain pan might be rusty or have a broken condensate pump. Replacing your pan or pump requires a professional, so contact us at 314-325-7552 for assistance.

Why Won’t My Air Conditioning Stop Leaking Freon?

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

It’s good 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 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 pro like B & B Heating & Cooling to fix an air conditioner coolant leak. In many situations, it may just be better to schedule air conditioning installation since Freon is expensive. Manufacturing of this coolant was halted in 2020 because of its damaging effects on the ozone layer. As a result, only reduced recycled quantities are available.
