What to do if my Royal Sovereign International ARP-908 is not cool enough?

  Marie KimAug 4, 2025
  If your Royal Sovereign International Air Conditioner isn't cooling effectively, ensure all windows and doors in the room are closed. Check that the exhaust air hose is tightly connected and as straight as possible to avoid blockages. Also, make sure air inlets and outlets are unobstructed. Remove any heat sources from the room and try decreasing the set temperature. Finally, the air filter might be dusty, so clean it.
