Goodman air conditioner freezes up with ice on the indoor coil or refrigerant lines

Safety first: Turn off the cooling mode at the thermostat to prevent compressor damage. You can set the fan to ON to help melt ice.

Steps to correct:

• 1. Thaw the system: Turn off cooling for several hours until all ice has melted. Place towels under the air handler or furnace to catch water.
• 2. Replace filters: Install new filters in the Goodman indoor unit.
• 3. Open vents: Ensure all supply and return vents are open and not blocked.
• 4. Check blower operation: After thawing, run the fan and confirm strong airflow from vents.

When to call a professional: If icing recurs, a technician should check refrigerant charge, blower performance, and duct static pressure.
