Clogged Air FiltersThere 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.
Condensate Drain Line is CloggedClogged 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.
Overflowing or Faulty Drain PanUnderneath 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 FrozenFrozen 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.
