When your air conditioner is running properly, your house 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 dangerous 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, repairing a leak will require skilled air conditioning repair.

In most cases, you can prevent your air conditioner from leaking by requesting 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.

Why Does My AC Unit Leak Water?

Water is a natural result of air conditioning. 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 occurs as the air cools, flows into a drain pan and drains out of your house through a condensate drain line.

Due to the condensation process, having water leak is a common problem. We regularly 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 clog the condensate drain line. This can lead to water backing up inside your house. Our Air Alliance Team pros can break up clogs and get water flowing again smoothly. Reach us at 636-206-4584 for assistance.

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
  • Extending your air conditioner’s life span

A dirty air filter can reduce airflow, make the coil extremely cold and cause it to freeze. As the coil melts, it can make the drain pan overflow. We recommend checking your air filter if you haven’t changed 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 malfunctioning condensate pump. Replacing your pan or pump requires a pro, so contact us at 636-206-4584 for assistance.

Why Won’t My Air Conditioning Stop Leaking Freon?

Your air conditioner uses coolant to move heat. If your air conditioner was put in before 2011, it likely uses 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 has one. They include:

  • Air that seems warmer or more humid than normal
  • Bubbling or hissing noises near the air conditioner
  • Sweet smell near the air conditioner
  • Frozen evaporator coil

Freon is hazardous to your health if handled improperly, so you’ll need an HVAC professional like Air Alliance Team to fix an air conditioner coolant leak. In many situations, it might just be better to schedule air conditioning installation since Freon is expensive. Manufacturing of this coolant was stopped in 2020 due to its harmful effects on the ozone layer. As a result, just limited recycled quantities are available.
