AC Leaking Water in Chicago Ridge? Fast Same-Day Repair
Discovering water pooling around your furnace, dripping from ceiling vents, or leaking from your AC unit can be alarming. Clucas Mechanical provides fast AC leak diagnosis and repair in Chicago Ridge to prevent water damage and restore your system.
Why Is My AC Leaking Water?
1. Clogged Condensate Drain Line (Most Common)
Your AC produces 5-20 gallons of condensation per day as it removes humidity from your home. This water drains through a PVC pipe or tubing. Over time, algae, mold, and debris clog the drain, causing water to back up and overflow.
Symptoms: Water pooling near furnace, dripping from condensate pan, musty odor
Repair: Professional drain clearing with wet/dry vacuum, drain snake, and algaecide treatment ($150-$300).
2. Frozen Evaporator Coil
If airflow is restricted (dirty filter, closed vents, duct issues) or refrigerant is low, your evaporator coil can freeze. When ice melts, it overwhelms the drain pan and leaks into your home.
Symptoms: Ice on copper lines, reduced cooling, water leaks after AC shuts off
Repair: Identify root cause (replace filter, fix airflow issues, repair refrigerant leak), safely defrost coil ($150-$800 depending on cause).
3. Failed Condensate Pump
Many Chicago Ridge basement furnaces use condensate pumps to lift water up to a drain. If the pump fails or loses power, water accumulates and overflows.
Symptoms: Loud buzzing from pump, water in pan, AC shuts down on safety float
Repair: Replace condensate pump ($250-$500 installed).
4. Cracked or Rusted Drain Pan
Older AC systems (15+ years) can develop cracks or rust holes in the drain pan underneath the evaporator coil, causing water to leak directly onto the floor or ceiling below.
Symptoms: Visible rust or cracks, water leaking despite clear drain
Repair: Replace drain pan ($300-$700) or, if system is old, consider AC replacement.
5. Improper Installation or Slope
If the condensate line wasn't installed with proper downward slope or if the furnace/coil isn't level, water can't drain properly and backs up.
Symptoms: Recurring leaks even after drain cleaning, slow drainage
Repair: Re-route drain line with correct slope or level the unit ($200-$600 depending on access).
6. Disconnected or Damaged Drain Line
Drain lines can become disconnected during other HVAC work, or rodents and pests can damage plastic tubing, causing leaks before water reaches the drain.
Symptoms: Water leaking from disconnected joint, visible damage to drain line
Repair: Reconnect or replace damaged section of drain ($100-$300).
Chicago Ridge-Specific AC Leak Challenges
Chicago Ridge homes, many built in the 1960s-1980s, present unique drainage challenges:
- Basement furnaces with uphill drains: Require pumps that can fail during power outages or after years of use
- Finished basements with hidden drain pans: Leaks may go unnoticed until significant damage occurs
- High water tables: Sump pump backups can affect condensate drainage in some areas
- Multiple HVAC additions over decades: Patchwork drain routing that doesn't follow best practices

What You Can Try Before Calling
- Turn off your AC immediately to prevent further water damage
- Check and replace your air filter—a clogged filter is the #1 cause of frozen coils and leaks
- Locate your condensate drain line (usually white PVC pipe exiting near the furnace) and check if water is draining when AC runs
- If you have a condensate pump, check if the reservoir is full and pump is running when AC operates
- Check for visible ice on the copper refrigerant lines—if frozen, turn off AC and call for service
- Place towels or a bucket under the leak to minimize water damage while waiting for repair
Preventing Future AC Water Leaks
- Schedule annual AC tune-ups that include drain cleaning and inspection ($89-$149)
- Change filters monthly during cooling season to maintain proper airflow
- Install a condensate drain alarm to alert you before major leaks occur ($50-$150)
- Add drain line treatment tablets quarterly to prevent algae growth ($10-$20)
- Ensure proper airflow—don't close more than 20% of vents, keep furniture away from returns
Frequently Asked Questions
- Why is my AC leaking water inside my Chicago Ridge home?
Most indoor water leaks are caused by clogged condensate drains, frozen evaporator coils, or failed condensate pumps. Our technicians diagnose and fix the root cause to prevent water damage. - Is water leaking from my AC dangerous?
While not immediately dangerous, water leaks can cause significant property damage including ceiling damage, mold growth, and ruined flooring. Address leaks quickly to minimize damage. - How much does AC leak repair cost?
Condensate drain cleaning: $150-$300. Condensate pump replacement: $250-$500. Evaporator coil repairs or defrosting: $150-$800 depending on cause. We provide exact pricing after diagnosis. - Can I fix an AC water leak myself?
You can try clearing the condensate drain with a wet/dry vacuum or checking for a full condensate pan, but frozen coils and pump failures require professional tools and refrigerant expertise. - How long does AC leak repair take?
Drain cleaning takes 30-60 minutes. Pump replacement takes 1-2 hours. Fixing frozen coil issues may take 2-4 hours including defrost time.
