When your air conditioner is running properly, your house will be cool and dry. A leaking air conditioner is frustrating but isn’t necessarily dangerous. It depends on whether it’s leaking water or refrigerant.

Water leaking from your air conditioner isn’t dangerous 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 case, fixing a leak will require skilled air conditioning repair.

In most cases, you can stop your air conditioner from leaking by requesting yearly air conditioning maintenance. During your appointment, an HVAC technician will closely examine your system for problems and clean it. This service helps ensure worry-free cooling and might even boost 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 air conditioning. 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 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 Clogged

Over time, mold can clog the condensate drain line. This can result in water backing up inside your house. Our Air Alliance Team pros can break up clogs and get water draining again smoothly. Give us a call at 636-206-4250 for assistance.

Air Filter Is Dirty

We recommend changing flat filters monthly 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 reduce airflow, make the coil very cold and freeze it. As the coil melts, it can overwhelm the drain pan. We recommend inspecting your air filter if you haven’t changed it lately and your air conditioner is leaking water indoors.

If this doesn’t resolve the issue, your drain pan might be rusty or have a broken condensate pump. Replacing your pan or pump requires a professional, so call us at 636-206-4250 for assistance.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner uses 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 through metal and cause leaks.

It’s good to know about air conditioner Freon leak symptoms in case your system has one. They include:

  • Air that seems hotter or more humid than usual
  • Bubbling or hissing sounds by the air conditioner
  • Sweet smell near the air conditioner
  • Frozen evaporator coil

Freon is bad for your health if handled improperly, so you’ll want an HVAC pro like Air Alliance Team to repair an air conditioner coolant leak. In many situations, it may just be better to request air conditioning installation since Freon is expensive. Production of this coolant was halted in 2020 because of its damaging effects on the ozone layer. As a result, only limited recycled quantities are available.
