When you notice water pooling around your air conditioner, it’s natural to feel concerned. While some moisture is normal, visible leaks signal that something isn’t working as it should. At Hometown Heating and Air Conditioning, we help homeowners address AC problems quickly and effectively with targeted AC repair. If your AC is leaking water, here are the most common reasons why—and when it’s time to call in the professionals.
Clogged Condensate Drain Line
Your air conditioner not only cools the air but also removes humidity. This moisture is supposed to drain away through a condensate line. Over time, dirt, algae, or mold can clog the line, causing water to back up and leak inside your home. In some cases, you may even notice water damage or musty odors. Clearing clogs is one of the most common AC repair calls we receive.
Dirty Air Filters
A dirty air filter restricts airflow, which can cause the evaporator coil to get too cold and freeze over. When the ice melts, excess water can overflow the drain pan and appear as a leak around the unit. Replacing filters every one to three months helps prevent this issue and keeps your system running efficiently.
Damaged or Rusted Drain Pan
The condensate drain pan catches water that drips from the evaporator coil before it flows into the drain line. If the pan becomes rusted, cracked, or damaged, it won’t hold water properly, leading to leaks around your AC. Older systems are more prone to this problem and often require professional repair or replacement.
Low Refrigerant Levels
When refrigerant levels are too low, the evaporator coil may become too cold, causing ice to form. As the ice melts, it can overwhelm the drainage system and result in water leaks. Low refrigerant is usually caused by a leak and needs to be addressed by a professional technician. Simply refilling refrigerant without fixing the source of the problem is only a temporary solution.
Improper Installation
If your air conditioner was not installed correctly, drainage issues may develop. An improperly leveled unit, poorly connected drain lines, or undersized components can all contribute to water leaks. This is why it’s essential to rely on experienced professionals like the team at Hometown Heating and Air Conditioning for installation and repairs.
When to Call a Professional
While some causes of water leaks, like a dirty filter, are simple to fix, most require the knowledge and tools of a trained technician. You should call for professional AC repair if:
- You notice frequent or large amounts of water near your unit
- There are signs of water damage on walls, ceilings, or flooring
- The system is short cycling or blowing warm air
- You hear unusual noises or notice unusual odors from the unit
Delaying repairs can lead to bigger problems, including mold growth, electrical issues, and major system breakdowns.
