In this guide, our HVAC experts share proven solutions for AC leaking water, system shutdowns, frozen units, and more. Use these tips to take control of your central air emergencies before calling in a technician.
Common Causes of AC Not Cooling or Leaking Water
If your central AC stops cooling or begins leaking water, several issues may be to blame:
- Low refrigerant levels or refrigerant leaks
- Clogged condensate drain lines
- Frozen evaporator coils due to airflow blockages
- Compressor or fan motor failure
- Blocked air vents or dirty filters
These problems often surface suddenly, so knowing how to spot them is essential for timely AC emergency repair.
Why Quick AC Repairs Matter
Delaying repairs when your AC is not cooling can lead to:
- Higher energy bills from inefficient cooling
- Water damage from leaks
- Mold growth due to excess humidity
- System failure from overworked components
Fast action helps avoid long-term damage and keeps your AC system running efficiently.
Safety Tips Before You Troubleshoot
Before attempting any DIY fixes:
- Turn off power at the breaker to avoid shocks
- Wear gloves and safety goggles
- Refer to your unit’s manufacturer manual
- Call a professional for refrigerant or electrical issues
