Unit operates but energy consumption seems unusually high.

Safety first: Standard cleaning and settings adjustments only.

• Step 1 – Clean filters and coils: Dirty components force the system to run longer. Clean as previously described.
• Step 2 – Optimize setpoint: Set cooling to around 24–26°C instead of very low temperatures to reduce compressor runtime.
• Step 3 – Use ECO mode: Many Samsung ACs have an ECO or energy-saving mode; enable it for moderate conditions.
• Step 4 – Seal room: Close doors and windows, use curtains or blinds to reduce solar gain, and seal obvious air leaks.
• Step 5 – Schedule operation: Use the timer function to avoid running the AC when the room is unoccupied.
