  • Corrosion within the system components

How to Address Water Leaks

Addressing water leaks involves several steps. Always prioritize safety and consider consulting a professional if you’re unsure.

Step 1: Turn Off the System

Before inspecting or repairing, shut off the HVAC system to prevent further damage or water flow.

Step 2: Locate the Leak

Check the condensate drain line, drain pan, and refrigerant lines for visible signs of leaks or damage.

Step 3: Clear Blockages and Repair Damages

Remove any clogs from drain lines, repair or replace damaged drain pans, and tighten fittings. Use appropriate sealants for minor leaks.

Step 4: Prevent Future Leaks

Regular maintenance, such as cleaning drain lines and inspecting system components, can prevent leaks from recurring.
