To determine if your old thermostat is working, first, ensure it's set to the correct mode (heating or cooling) and adjust the temperature setting to trigger the system. Listen for any clicking sounds from the thermostat, which indicate it’s trying to activate the HVAC system. Next, check airflow from vents for warm or cool air. Inspect the display or status lights for error messages or low battery indicators. If the system doesn't respond, consider replacing the batteries or consulting a professional, as these are common troubleshooting steps.
