Air conditioning leaks can lead to significant issues if not handled quickly. Knowing the common causes can help you address them before they become costly problems. Here are some typical reasons why AC units leak and what you can do to fix them.
Clogged Drain Line
Over time, dirt and debris can block the drain line, preventing water from flowing away from the unit. This causes water to back up and leak. You can clear minor clogs with a wet/dry vacuum or flush the line with a bleach-water solution. For severe clogs, professional help is recommended.
Dirty Air Filters
When air filters are clogged, they restrict airflow, causing the evaporator coil to freeze. As it defrosts, excess water may leak. Replacing air filters every one to three months can prevent this and improve system efficiency.
Low Refrigerant Levels
If refrigerant is low, it can cause the evaporator coil to freeze and then leak when it melts. Low refrigerant often indicates a leak, which requires a professional to fix and recharge the system.
Damaged Drain Pan
The drain pan catches condensation and directs it to the drain line. If it’s rusted or cracked, water can escape and cause leaks. Inspect the pan for any visible damage, and replace it if needed.
Improper Installation
Sometimes, an AC unit might be improperly installed or incorrectly sized for the space, leading to poor drainage. If you experience frequent leaks with a relatively new unit, this might be the issue. It’s best to have a professional inspect and address any installation errors.
Blocked Condensate Pump
In units that use a condensate pump, such as those located in basements or attics, a clogged or malfunctioning pump can cause leaks. Cleaning or replacing the pump can often solve this issue.
Frozen Evaporator Coil
Apart from low refrigerant or restricted airflow, dirty coils can freeze and then melt, causing leaks. Regular maintenance, including professional cleaning, can prevent these issues from escalating.
