The first step to connecting your air conditioner (AC) to Wi-Fi is to make sure that you have a compatible model. Many newer models of ACs are now able to connect to Wi-Fi, but not all. Check the user manual for your particular unit and see what type of wireless connections it supports. If your AC does support a Wi-Fi connection, the next step will be setting up the connection itself. This typically involves downloading an app onto either your smartphone or computer and following the instructions on screen in order to establish a secure connection between your AC and Wi-Fi network. Once this is done, you can use the app in order to control settings like temperature and fan speed from anywhere with an internet connection!
