Yes, a window air conditioner can be installed and operated without a wall thermostat. Window air conditioners typically have built-in controls and temperature settings on the unit itself, allowing you to adjust the cooling settings directly.
When you install a window air conditioner, you'll typically find control buttons or a control panel on the front or top of the unit. These controls typically include options to adjust the temperature, fan speed, and mode of operation (such as cool, fan-only, or energy-saving modes). You can set the desired temperature directly on the unit, and it will work based on the temperature sensor built into the AC.
While window air conditioners without a wall thermostat lack the convenience of controlling the temperature from a separate location, they are still capable of providing cooling based on the temperature settings you choose on the unit itself. You can adjust the settings as needed to maintain a comfortable indoor environment.
However, some higher-end window air conditioners may offer additional features that can be controlled remotely via a smartphone app or a separate remote control. These features may include scheduling, temperature adjustments, or monitoring the unit's status. If your window air conditioner has these capabilities, you can take advantage of the additional control options.
Remember to refer to the manufacturer's instructions and guidelines when installing and operating your window air conditioner to ensure safe and optimal usage.
