Few things are more frustrating than noticing a puddle of water near your air conditioner. A leaking AC can lead to bigger problems, like water damage, mold growth, and even system failure, if left unchecked. But don’t worry—before you panic, let’s go over what might be causing the leak and what you can do to fix it or when you should call a professional.
Why Is Your AC Leaking?
Your air conditioner works by pulling humidity from the air; that moisture needs somewhere to go. Normally, it drains away through a condensate line, but when something goes wrong, leaks can happen. Here are some common causes:
- Clogged Drain Line – The most common reason for an AC leak is a clogged condensate drain line. Over time, dirt, dust, and algae can build up, blocking the line and causing water to back up into your home.
- Dirty Air Filter – A dirty filter restricts airflow, which can lead to frozen coils. When those coils thaw, they can create excess water that might overflow.
- Low Refrigerant Levels – If your AC is low on refrigerant, the pressure in the system drops, which can also cause the coils to freeze. Again, when they thaw, excess water can appear.
- Damaged or Rusted Drain Pan – If your AC unit is older, the drain pan may be rusted or cracked, which allows water to leak onto the floor instead of draining properly.
- Improper Installation – If your AC wasn’t installed correctly, it might not be level, causing water to pool instead of draining as it should.
What to Do If Your AC Is Leaking
- Turn Off Your AC – First things first, turn off your system to prevent further damage. Running an AC with a leak can lead to electrical issues or frozen components.
- Check the Air Filter – A clogged filter is an easy fix. If it’s dirty, replace it with a clean one and see if the problem improves.
- Look at the Drain Pan – If the pan is cracked or rusted, you may need to replace it.
- Call a Professional – If you suspect a refrigerant issue or can’t pinpoint the problem, it’s best to call an expert. A trained HVAC technician can safely diagnose and repair leaks before they cause serious damage. If you need an air conditioner repair in Tulsa, OK, make sure to call an experienced professional to get your system back on track. A properly working AC keeps your home comfortable and helps prevent costly breakdowns down the road.
