Prevent AC Water Damage: HVAC Maintenance Tips
38|Stop Air Conditioning Leaks Before They Flood Your Home
39|Air conditioning systems produce gallons of condensation daily during Cleburne's hot summers. When AC drainage systems fail, water floods attics, ceilings, and walls — causing extensive damage. We respond to dozens of AC-related water damage calls every summer. Most are preventable with simple maintenance.
43| 44|How AC Systems Create Water Damage
45|Your air conditioner removes humidity from indoor air. This moisture condenses on cold evaporator coils and drips into a drain pan. A condensate line carries water outside or to a drain. When this system fails, water overflows and floods your home.
46| 47|Clear Condensate Lines Regularly
48|Algae, mold, and debris clog condensate drain lines, blocking water flow. Clear your AC drain line every 3 months:
49|-
50|
- Locate the PVC drain line (usually near outdoor AC unit) 51|
- Pour 1 cup bleach or vinegar into the drain pan access port 52|
- Wait 30 minutes for solution to kill algae 53|
- Flush with 1 gallon of water 54|
- Check that water drains freely 55|
Inspect Drain Pans
58|Primary and emergency drain pans rust through or crack over time. Check pans annually:
59|-
60|
- Remove AC access panel 61|
- Inspect primary pan for rust or cracks 62|
- Test emergency pan by pouring water into it 63|
- Replace rusty or damaged pans immediately 64|
Install Overflow Sensors
67|Float switches shut off your AC if drain pans fill with water. This prevents overflow damage. Professional HVAC techs install sensors for $100-200 — cheap insurance against thousands in water damage.
68| 69|Change Air Filters Monthly
70|Dirty filters restrict airflow, causing evaporator coils to freeze. When ice melts, excess water overwhelms drain systems. Change filters every 30 days during cooling season, every 90 days in mild weather.
71| 72|Schedule Professional HVAC Service
73|Annual AC maintenance catches problems before they cause water damage. Technicians clear drain lines, inspect pans, test float switches, and identify wear that leads to leaks.
74| 75|Signs of AC Water Damage
76|Call for emergency water damage service if you notice:
77|-
78|
- Water stains on ceilings below AC unit 79|
- Musty odors near vents 80|
- Standing water in drain pan 81|
- AC cycling on and off (may indicate overflow sensor) 82|
- Wet insulation in attic near air handler 83|
