Seeing water around your air conditioner is a sign that something inside the system isn’t working right. Leaks can originate from clogged drains, frozen coils, or even dirty filters; each requires a different solution. If you don’t catch the problem early, you could end up with water damage or mold where you least expect it. The team at Affordable Service Solutions Heating & Air Conditioning in Richmond, KY, helps homeowners like you understand these AC issues before they worsen.
Clogged Drain Lines
When your AC unit runs, it doesn’t just cool the air. It also pulls moisture out of it. That moisture turns into water and drains through a small pipe called a condensate line. If this line gets blocked with dirt or dust and the water has nowhere to go, it backs up into the drain pan and can spill onto the floor. You may notice a puddle under your indoor unit or near the closet where the system is located. This type of leak often occurs during humid weather or when your air conditioner operates frequently. You can check the drain line for clogs by looking near the indoor unit. If it’s wet, looks green, or appears slimy, the pipe may need to be cleaned or cleared.
Frozen Coils
If your air conditioner isn’t getting enough air, the coils can freeze. It happens when warm air doesn’t move across the coil like it should. The coil gets too cold and turns condensation into ice. Then, water drips when the unit shuts off or the ice melts. You might notice the system blowing less air or none at all. Alternatively, you may hear strange sounds when it starts up again. Sometimes, the air filter is to blame. If it’s dirty, air can’t flow through properly. At other times, low refrigerant can also cause the same freezing issue. Either way, the water has to go somewhere when those coils thaw out. If the drain pan can’t hold it all, it leaks.
Low Refrigerant Levels Can Lead to Ice and Leaks
Refrigerant is the liquid that helps your AC cool the air. Everything has to work harder when there isn’t enough of it in the system. That includes the evaporator coil, which can get too cold and start to freeze. You might see water near the air handler or around the indoor unit. You could also hear a hissing sound, which means refrigerant might be leaking out. Low refrigerant isn’t something you can refill on your own. The system is sealed and requires a trained technician to repair it safely.
Broken Condensate Pump Can Let Water Pool Inside
In some homes, your AC doesn’t drain water by gravity. It uses a small pump to push water up and out of the system. This is called a condensate pump. If the pump breaks or the power to it fails, the water inside the system can accumulate. You might hear a faint buzzing or humming from the pump that won’t stop, or you might not hear anything at all if the pump is completely dead. Either way, water can’t move where it needs to go. Eventually, it fills the pan and spills out onto your floor or wall. If your system is located in a basement or attic, this type of leak can cause serious damage quickly.
Rusty or Cracked Drain Pans Let Water Escape
Every AC system has a shallow tray called a drain pan. Its job is to collect water dripping off the coils before draining through the pipe. These pans are usually made of metal or plastic. If they rust, crack, or shift out of place, water slips out and leaks onto the floor. You might not notice until you see ceiling stains or smell something musty near the unit. Drain pans can wear out after years of use, especially if exposed to water that never fully drains. Checking the pan is simple but can be tricky if it’s hidden.
