When your air conditioner is working 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 bad but can cause a lot of damage to your house. On the other hand, a coolant leak is harmful to you and the environment. In either case, repairing a leak will require professional 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 inspect your system for problems and clean it. This service helps ensure worry-free cooling and may even improve energy efficiency.

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 moves over it. Condensation forms 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 occurs:

Drain Line Is Clogged

As time passes, mold can block the condensate drain line. This can lead to water backing up inside your house. Our Pliescott HVAC Services LLC pros can break up clogs and get water flowing again smoothly. Give us a call at 410-228-4822 for help.

Air Filter Needs to Be Changed

We recommend replace flat filters once a month 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 reduce airflow, make the coil extremely cold and cause it to freeze. As the coil defrosts, it can make the drain pan overflow. 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 fix the problem, your drain pan might be rusty or have a broken condensate pump. Getting a new pan or pump requires a professional, so call us at 410-228-4822 for help.

Why Is My Air Conditioner Leaking Freon?

Your air conditioner uses coolant to transfer 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 important to know about air conditioner Freon leak symptoms in the event your system develops one. They include:

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

Freon is bad for your health if handled improperly, so you’ll need an HVAC pro like Pliescott HVAC Services LLC 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 stopped in 2020 because of its damaging effects on the ozone layer. As a result, only reduced recycled quantities are available.
