Read on to learn what typically causes your air conditioner to leak and how to fix it. 

Clogged Air Filters 

There are plenty of reasons why your air conditioner may be leaking, but clogged air filters are usually the number one cause. Air filters become clogged with dirt and other debris over time which can inhibit proper airflow within your unit. If these crucial parts are clogged then other issues will begin to arise. For example, the lack of airflow may lead to frozen evaporator coils that drip water, thus resulting in a puddle of water. 

To fix a clogged air filter, simply replace the filter with the appropriate type dictated by:

  • Where you live.
  • Size of the home.
  • Seasonal temperatures.
  • Household allergies or health conditions.

Make sure to replace the air filter every 1-2 months to maintain quality airflow. Some filters may only need to be replaced every 3-4 months if it has specialized material. If you need help figuring out what type of filter you need, search “air conditioning contractors near me.”

Condensate Drain Line is Clogged

Clogged condensate drain lines are also likely culprits of a leaky air conditioner. This is especially true if it is not regularly cleaned or inspected. It is important to clear the line frequently because it can become blocked with debris. If you want to clear the drain by yourself, follow these tips: 

  • Turn off the unit before trying to clear the drain yourself. 
  • Find the air handler drain pan and unscrew the cap on the pipe near it. 
  • Pour vinegar through the drain line which will kill any fungi that might have developed overtime. 
  • Use a vacuum with attachments to clear the line. 

If you are unable to remove the blockage in the condensate line, it might be time to call in the big guns. A professional HVAC team will be able to  remove the clog in no time and have your air conditioner running like new. They will also be able to give you tips on how to prevent a clog in the future. 

Overflowing or Faulty Drain Pain

Underneath your system there is a compartment that holds the evaporator coils and drain pan. The drain pan catches dripping condensation. If you suspect that your unit is leaking water, inspect the drain pan for any leaks or overflow. There are two primary drain pans that need to be checked, one housed underneath the coils and one underneath the unit. 

To temporarily fix a crack in the pan, a waterproof sealant may be applied. However, if there is a crack in the drain pan it will ultimately need to be replaced. The seal is only a temporary fix, so if the pan is not replaced soon, then you may face more issues in the future. Contact a technician for HVAC replacement parts and professional installation. 

For an overflowing drain pan all you have to do is dump out the water. You can also use a wet/dry vacuum to avoid any emptying frustrations.

Evaporator Coils are Frozen 

Frozen evaporator coils are a common contributor to leaky air conditioning units. Evaporator coils may become frozen for a number of reasons:

  • Low refrigerant levels will cause ice to form on the coils because heat cannot be absorbed.
  • The evaporator coils are dirty. 
  • Blocked vents or registers that inhibit airflow. 
  • Clogged air filters. 
  • Broken fan or motor. 

If your evaporator coils are frozen the best thing to do is turn off the unit and let the coils thaw out. If you do not thaw the coils then you may end up with further issues. To prevent this in the first place, make sure to schedule a seasonal HVAC maintenance appointment with your local HVAC company. 

Correct Installation 

Did you recently have your HVAC unit replaced and now it is leaking water? Although there may be a few explanations for why this might be happening to your unit, the simple answer is that it may have been installed incorrectly. It is important to hire a licensed and properly trained HVAC technician to get the job done right the first time. A correct installation will ensure that your unit is working properly without any issues. 

When you choose a dependable contractor, you can feel confident that your until will be installed without issue. Contact your local HVAC technicians for expert advice and correct installation of your new HVAC unit.
