A leak from your air conditioning unit is more than a minor problem. Something is wrong if you see water leaking from your AC inside your home. While a small leak may not do much harm in the short term, it will more than likely result in water damage, mold, and a less efficient system over time. Let’s explore the causes, what to do about the causes, and how GreenWorks AC can help.
Most Common Causes of Indoor AC Leaks
1. Clogged Drain Line
A clogged condensate drain line is typically the most common cause. An accumulation of dirt, dust, or mold can stop the pipe, forcing water to back up into your home.
2. Clogged Air Filter
When the air filter is dirty, it restricts airflow across the evaporator coil, and it freezes up. When it thaws, it can produce enough water to leak out of the casing.
3. Low Refrigerant
A low refrigerant situation reduces pressure in the A/C and leads to a frozen coil. When it thaws, it can lead to large puddles around the indoor unit.
4. Damaged Drain Pan or Rusted Drain Pan
The drain pan collects the condensation that the A/C system produces. If it is cracked or rusted, water falls outside the drain pan. This is only a problem with older units.
5. Improper Installation or Poor Maintenance
A unit that is not level can create an improper drainage situation. Poorly sealed ductwork can lead to the collection of water in unwanted areas. Lastly, a cascade of small issues can lead to bigger problems when a unit is not serviced regularly.
What to Do Immediately
Turn Off the AC: Shut it down to stop further leaking and avoid electric hazards.
Clean the Water: Wipe up standing water to prevent mold and flooring damage.
Check the Air Filter: Replace if it’s clogged. This might help the airflow and reduce freezing.
Look at the Drain Line: If accessible, try clearing the blockage using a vacuum or pipe cleaner. Still, a professional fix is often safer and more effective.
Why You Shouldn’t Ignore It
Letting the air conditioner that is leaking water in your house go unchecked will likely cause bigger problems:
- Mold growth inside walls or near the air handler.
- Damage to ceilings, floors, or insulation.
- Higher energy bills are due to an inefficient system.
- Early breakdowns or full system failure.
This isn’t just a comfort issue — it’s about home safety and system health.
