Goodman air conditioner leaks water inside the house around the air handler or furnace

Safety first: Turn off power to the indoor unit at the breaker to avoid electrical hazards near water.

Steps to clear and repair:

• 1. Locate the drain line: Find the PVC drain exiting the Goodman air handler or furnace coil cabinet. Identify the cleanout tee or access point.
• 2. Clear the line: Use a wet/dry vacuum on the outside drain termination to suck out algae and debris. Seal around the pipe with a rag for better suction.
• 3. Flush with water and vinegar: At the indoor cleanout, pour a mixture of warm water and white vinegar into the drain to help dissolve buildup.
• 4. Inspect drain pan: Remove the coil access panel and check the primary and secondary drain pans for cracks or rust-through. If damaged, the pan or coil assembly may need replacement.
• 5. Check condensate pump (if present): Ensure the pump has power and the float switch moves freely. Clean the pump reservoir and discharge line.

When to call a professional: If leaks persist or the pan is damaged, a technician should evaluate for pan replacement, coil reinstallation, or drain line reconfiguration.
