Why Is My Air Conditioner Leaking Water?
Water leaking from your air conditioner can be very frustrating. You might look down and notice puddles on the floor or water dripping from your window or portable AC unit and think, “Why is my air conditioner leaking water?”
At Quick Fix HVAC Service, we hear this question every summer from Cleveland homeowners—and for good reason. If left unrepaired, an AC leak can damage walls, flooring, and even the electrical sector inside your house.
In this guide, we’ll explore the most common causes of air conditioner leaks, what you can do about them, and when it’s time to call for 24 hour air conditioner repair in Cleveland.
Is It Normal for an Air Conditioner leaking Water?
To some degree—yes. When your AC is running, it pulls moisture from the air, which condenses on the evaporator coil. That water normally drains through a condensate line and exits your home.
However, it’s not normal for water to drip indoors, pool beneath the unit, or leak from the sides or bottom. These symptoms indicate something is wrong.
Top Reasons Why is Your Air Conditioner Leaking Water?
Clogged Condensate Drain Line
Over time, your AC’s drain line can get blocked with dust and mold. When that happens, the water has nowhere to go—and ends up leaking inside your home. Sometimes flushing the drain line during regular maintenance can prevent this issue.
Frozen Evaporator Coil
If your coil freezes due to restricted airflow or low refrigerant levels, it will eventually melt. That melted ice can overflow the drain pan, causing a visible leak. In that case, you need to check your air filter and refrigerant levels. If the problem continues, Contact Quick FIx HVAC Service.
Damaged or Rusted Drain Pan
A cracked or corroded drain pan can’t hold the moisture your system collects, causing leaks on the floor. To solve this, replacing the pan is a simple repair but should be handled by a technician.
Dirty Air Filter
A dirty air filter restricts airflow, which causes your system to work harder and may lead to coil freezing. You need to change the AC filter every 1-3 months, depending on usage and air quality.
Improper Installation
If your window AC or portable unit is not installed level, or if the drain isn’t connected properly, water won’t flow out as it should. Instead, it leaks inside. Make sure the unit is slightly tilted backward and drain systems are clear.
Specific AC Leaks and What They Mean
Portable Air Conditioner Leaking water?
Your tank might be full or the hose might be blocked. Some units also have an internal pump that can fail.
Window Unit Dripping from the Bottom?
It may not be sloped enough for water to drain outward, or the drain hole may be clogged.
