Daikin furnace runs but some rooms are too cold while others are too warm.

Safety: Adjust only accessible dampers and registers; do not modify internal furnace settings without training.

Steps to check:

• Register adjustments: Slightly close registers in overheated rooms and fully open registers in cold rooms.
• Check for blockages: Inspect visible duct runs and registers for crushed sections, closed dampers, or obstructions.
• Filter and coil: Replace the filter and have the indoor coil cleaned if airflow seems weak overall.

For persistent imbalance, a technician should perform a duct analysis and adjust Daikin blower settings or recommend duct modifications.
