Is your air conditioner leaking water or experiencing other issues? The professionals at Kova Heating & Cooling are here to provide fast and effective solutions.
Your air conditioner works hard to keep your home cool and comfortable by removing both heat and humidity from the air. Normally, the moisture it removes gets condensed and drained safely outside. However, when you discover puddles of water inside your home, it’s a clear sign that something isn’t working properly.
Important: If you notice water leaking from your AC unit, turn it off immediately and contact our experts. Continuing to run a leaking system can cause extensive water damage to your home and potentially lead to complete system failure.
At Kova Heating & Cooling, we provide comprehensive HVAC services throughout Portland & Vancouver, and we’re committed to helping our neighbors stay comfortable year-round.
Common Causes of AC Water Leaks
1. Dirty Air Filters
One of the most frequent culprits behind AC water leaks is a dirty air filter. Your filter plays a crucial role in keeping your system running smoothly by catching dust, dirt, and other contaminants before they reach the evaporator coils.
When filters become clogged (typically after 60-90 days of use), several problems can occur:
- Debris bypasses the filter and accumulates on evaporator coils
- Restricted airflow prevents proper heat absorption
- Coils can freeze due to inadequate heat transfer
- Frozen coils eventually melt, creating excess water that overwhelms the drainage system
While changing your filter might help prevent future issues, if your system is already leaking, professional repair of the evaporator coils is likely needed.
2. Clogged Condensate Drain
Your AC system relies on a condensate drain to remove the water it pulls from your home’s air. When this drainage system fails, water has nowhere to go but into your home.
Common drainage problems include:
- Clogged drain lines filled with mold, dirt, or debris
- Cracked or damaged drain pans
- Disconnected drain lines
- Rusted or corroded components
You can inspect visible portions of your drain system for obvious damage, but clearing clogs typically requires professional equipment and expertise.
3. Low Refrigerant Levels
If your AC is leaking water and struggling to cool your home effectively, low refrigerant could be the issue. Refrigerant is essential for heat absorption, and when levels drop due to leaks:
- Evaporator coils become too cold and freeze over
- Ice buildup eventually melts, creating more water than your drain system can handle
- Water overflows into your home
This problem requires professional diagnosis to locate the refrigerant leak, repair it, and restore proper system function.
4. Excessive Condensation
While some condensation is normal in AC operation, too much can cause serious problems. Several factors can lead to excessive condensation:
Airflow Issues:
- Dirty filters restrict air movement
- Blocked vents or ducts
- Inadequate system sizing
Insulation Problems:
- Poorly insulated ductwork
- Insufficient attic insulation
- Gaps in the building envelope
Environmental Factors:
- High indoor humidity
- Poor ventilation
- Roof leaks increase moisture levels
5. Improper Installation
Installation issues often become apparent shortly after a new system is installed. Common installation problems include:
Window Units:
- Incorrect angle (should tilt slightly backward for proper drainage)
- Inadequate support or sealing
Central Systems:
- Unlevel installation is preventing proper drainage
- Undersized drain lines
- Incorrect refrigerant levels
- Poor ductwork connections
Working with experienced HVAC professionals during installation prevents these costly issues.
