Water leaking from outdoor unit during heating mode (heat pump).

Safety first: Be cautious of slippery ice around the outdoor unit. Turn off power before removing panels.

• Step 1 – Determine if normal: In heating mode, it is normal for water to drip from the outdoor unit during defrost. Clear pathways so water can drain away from the building.
• Step 2 – Check drain holes: Inspect the base pan of the outdoor unit and clear any debris blocking drain holes.
• Step 3 – Ice buildup: If ice is blocking drainage, gently remove loose ice. Do not use sharp tools that can damage the coil or pan.
• Step 4 – Drain pan heater (if equipped): In very cold climates, ensure the drain pan heater (if installed) is connected and functioning. Replacement may be needed if failed.
