    Air conditioner

    03/08/2026

    I loved my other Costway mini split so much that I bought a second one. The first one I use in my living room and the second one is in my dining room. They work amazing and the cost is better than any other brand I have looked at. Ian planning on buying more for my bedrooms.

    Costway representative
  • Q:
    What is dry mode
    A:
    The dry mode on the air conditioner is designed to reduce humidity in the air without significantly cooling the room. This mode helps to create a more comfortable environment by removing excess moisture, making it particularly useful in humid conditions. It operates by cycling the compressor on and off to maintain a desired humidity level while minimizing temperature changes.
  • Q:
    At what temperature will it heat to
    A:
    The temperature adjustment range for heating is between 16°C to 32°C (approximately 60°F to 90°F) .
  • Q:
    Is this good for Canadian winters
    A:
    The model is not specifically designed for extremely cold weather. It is recommended to use it above 23掳F (-5掳C) for optimal heating performance, as the heating performance will decrease below that temperature.
