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 refrigerant.

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 stop your air conditioner from leaking by scheduling 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 performance and might even improve energy efficiency.

Why Does My AC Unit Leak Water?

Water is a natural byproduct 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 moves over it. Condensation forms as the air cools, drips 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 often receive 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 result in water backing up inside your home. Our Service Max Heating & Air Conditioning professionals can break up clogs and get water draining again smoothly. Give us a call at 360-255-5857 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
  • Decreasing breakdowns
  • Extending your air conditioner’s lifetime

A dirty air filter can restrict airflow, make the coil very cold and freeze it. As the coil defrosts, it can make the drain pan overflow. We suggest checking your air filter if you haven’t replaced it lately and your air conditioner is leaking water indoors.

If this doesn’t resolve the issue, your drain pan may be rusty or have a malfunctioning condensate pump. Replacing your pan or pump requires a pro, so call us at 360-255-5857 for assistance.

Why Is My Air Conditioner 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. As time passes, chemicals in Freon can eat through metal and create leaks.

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

  • Air that feels hotter or more humid than usual
  • Bubbling or hissing sounds by 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 Service Max Heating & Air Conditioning to repair an air conditioner coolant leak. In many situations, it might just be better to request air conditioning installation since Freon is expensive. Manufacturing of this coolant was halted in 2020 due to its damaging effects on the ozone layer. As a result, just limited recycled quantities are available.
