Step 6 · Verify Thermostat Settings

Access your thermostat's control interface. Verify that the system is set to the correct mode (e.g., 'Cool' for cooling, 'Heat' for heating, or 'Auto' if the system is designed to switch between modes automatically). Check that the set temperature is appropriate for the desired comfort level and that it is significantly different from the current room temperature to call for heating or cooling. Ensure the fan setting is appropriate (e.g., 'Auto' or 'On').
