Step-by-Step

  1. Check the Location of Your Thermostat: Ensure that your thermostat is installed away from direct sunlight, drafts, or heat sources. Ideally, it should be on an interior wall.
  2. Inspect the Thermostat Settings: Review the programming on your thermostat. Make sure it’s set correctly for your desired heating or cooling schedule.
  3. Assess the Wiring: Turn off the power to your HVAC system and remove the thermostat cover. Check for loose or corroded wires. Reconnect or replace as necessary.
  4. Calibration Check: Use a level tool to ensure the thermostat is mounted straight. An uneven thermostat can affect its readings.

  8. Monitor Performance: After adjustments or installation, monitor the thermostat’s performance over the next few days to ensure it holds the desired temperature.
