      If your Seabreeze Air Conditioner isn't cooling or heating efficiently, ensure the temperature setting is correct. Check for obstructions in the inlet or outlet vents and make sure the filter is clean. Keep windows and doors closed, set the fan to a higher speed, and remove any heat sources from the room.

    Why is my Seabreeze Air Conditioner leaking water outside?
    • T
      Teresa BoyleAug 28, 2025
      Water leakage in the outdoor unit of your Seabreeze Air Conditioner is normal in certain situations. When the unit is running in Auto Defrosting mode, ice will thaw and drip into the pan. Also, when the unit is running in HEAT mode, water adhered to the condenser coil drains into the pan.

    Why is my Seabreeze Air Conditioner making noise inside?
    • L
      laurensandersSep 3, 2025
      The noise emitted from your Seabreeze Air Conditioner's indoor unit is normal in some cases. When defrosting starts or stops, a sound may occur due to the refrigerant flow reversing directions. Also, normal refrigerant flowing in the unit can produce sound.
