    How to Use the Dry Mode on Your AC to Save Energy

    Do you know what the water drop button on your remote does? Dry mode dehumidifies the air and can save you a lot of money in summer.

    When the heat hits Madrid, the first thing we do is turn on the AC in cool mode (the snowflake symbol) and drop the temperature to 20 degrees. However, there is a button on your remote control that you are probably ignoring, and it could save you a lot of money: the Dry mode (the water drop symbol).

    ### What exactly does Dry mode do? Unlike Cool mode, which works at maximum power to lower the room temperature quickly, Dry mode focuses on reducing the humidity in the environment.

    By removing humidity, the "feels like" temperature drops drastically. You can be at 25ºC in your living room, but if the air is dry, you will feel much more comfortable than being at 23ºC with high humidity.

    ### Benefits of using Dry mode 1. Energy savings: In this mode, the compressor and fan run at a much lower speed and intermittently. This can mean savings of up to 20% on your electricity consumption. 2. Better for your health: It avoids aggressive thermal shocks and dries out your respiratory tract less than the intense cooling mode. 3. Protects your home: It keeps mold, dust mites, and the "stuffy" smell at bay on muggy days or during summer storms.

    ### When should you use it? Dry mode is perfect for days when the problem isn't extreme heat (like 40ºC in mid-August), but rather cloudy, rainy days or summer nights where the air feels "sticky" and muggy.

    If you notice that your AC is failing to remove humidity from the room or is dripping more than normal, it might need an inspection. Contact PowerPro Madrid. Send us a WhatsApp or call us for preventative maintenance.
