Why Is My Air Conditioner Leaking Water?

Water dripping out of an AC unit

There’s no substitute for a quality air conditioner service to keep your home comfortable. But what happens when your AC starts to leak water? It can be concerning for homeowners and a sign that something is wrong with your air conditioning system. Some of the leaking water is normal. Your AC system may leak if there is condensation or ice buildup on the coils.

Other times, it’s a sign that something more significant is happening with your air conditioner. Fortunately, there are a few common causes of AC leaks, and most of them can be fixed with the help of a professional. Here is why your air conditioner leaks water – and what to do about it.

Reasons Your AC Is Leaking Water

There are several reasons your AC system is leaking water. Here are some of the most common:

Clogged Condensate Drain Line

The condensate line is the pipe that removes excess condensation from the AC unit. If the line is clogged, water can back up and leak from the AC unit.

Frozen Evaporator Coil

Your evaporator coil is responsible for cooling the air. If it gets too cold, it can cause ice to form and melt, causing water to leak from the AC unit.

Clogged Air Filter

Blocked air filters can cause the evaporator coil to freeze, which leads to water leakage.

Malfunctioning Float Switch

Float switches detect water in the drain pan and turn off the unit when it gets too full. If the switch malfunctions, it can lead to water buildup and leaking.

Leaking Refrigerant Lines

Refrigerant lines can become corroded or cracked over time, resulting in refrigerant and water leaks.

Damaged Gaskets and Seals

Damaged gaskets and seals are no longer air or watertight. This can allow water to leak out of the AC unit.

How To Stop Your AC From Leaking Water

If your AC system is leaking water, there are a few things homeowners can do to try and solve the problem. 

  • Check the air filter: A clogged filter is the simplest place to start. Make sure it’s not clogged with dust and debris, and replace it if it is. 
  • Clean the drain line: Next, thoroughly clean the condensate drain line to ensure it’s not clogged or blocked.
  • Check the float switch: Look to see if there is a lot of water in the drain pan. If there is, the float switch could be malfunctioning.
  • Check for leaks: If you think there are refrigerant or water leaks, it’s time to call a professional to check the system and make any necessary repairs.
  • Insulate the AC unit: Insulating the AC unit can help prevent ice from forming on the evaporator coil, which reduces the risk of leaks.

While being able to check your AC system on your own can be helpful, it’s important to remember that a professional should always do AC repair and maintenance. DIY solutions can be dangerous. Plus, it’s easy to cause more damage to your AC system, making any repairs more expensive. For the best results and peace of mind, schedule professional AC services with Blue Frost Heating & Cooling.
