Rheem air conditioner runs but water drips from the indoor unit or from ceiling below air handler.

Safety first: Turn off power to the air handler. Be prepared for water spillage when opening panels.

• Clear drain line: Locate the condensate drain outlet near the indoor unit. Use a wet/dry vacuum to clear the line from the outside termination.
• Inspect drain pan: Remove the access panel and inspect the primary and secondary drain pans for cracks or rust-through. Replace damaged pans.
• Check slope: Ensure the drain line slopes continuously downward away from the unit. Adjust supports if necessary.
• Flush line: After clearing, pour a mixture of water and a small amount of vinegar or approved condensate cleaner into the drain pan to flush the line.

Warning: Water leaks can cause structural damage and mold. Address promptly.
