You’re walking past your air conditioner and notice a puddle of water. Or maybe you spot moisture around your vents. Suddenly, you’re wondering: “Why is my AC leaking water, and should I be worried?”
If you live in Havertown, Chester County, or Delaware County, you’re not alone; this is one of the most common calls we get during the summer. While some leaks are easy to fix, others could point to a bigger problem that needs quick attention.
Here’s what could be going on and what you can do about it.
-
Your Condensate Drain Line Is Clogged
When your AC cools the air, it also pulls out moisture. This water is supposed to drain outside through a small line. But over time, dust, mold, or debris can clog that line, sending water back into your home.
Fix: This is usually a quick fix for a pro. At Boyle Energy, we use special tools to clear the line, and regular maintenance can help prevent this from happening in the first place.
-
Your Air Filter Is Dirty
A clogged filter makes it harder for air to flow over the coil, which can cause the coil to get too cold and freeze. When it eventually thaws, the excess water can overflow your drain pan.
Fix: Swap or clean your filter every 1–3 months. It’s one of the easiest ways to keep your system running smoothly (and prevent leaks).
-
Your Refrigerant Is Low
Low refrigerant can cause your coil to freeze too, leading to the same thaw-and-leak mess.
Fix: Only a licensed HVAC tech can safely check and refill refrigerants. If it’s low, there may be a leak in the system that also needs repair.
-
Your Drain Pan Is Damaged
Older units sometimes have rusted or cracked pans that can’t hold water the way they should.
Fix: If the pan is compromised, it needs to be replaced, a simple job for a trained technician.
-
Your Drain Line Is Loose or Broken
Vibration or poor installation can cause your condensate line to disconnect or crack, letting water escape inside your home.
Fix: A pro can quickly reattach or replace the line so it drains properly.
Don’t Wait on a Leak
Even a small drip can lead to mold growth, ceiling stains, or costly damage if ignored. If you notice water around your AC, don’t put it off.
