Signs That It's to Replace Your ThermostatThermostats for your HVAC system can last for years, accurately communicating to your heating and cooling when it’s time to turn on or off. That said, whenever something goes wrong with the HVAC system, the thermostat is one of the parts that should be checked out first. Fortunately, thermostat replacement is usually relatively inexpensive.

Following are some troubleshooting tips for when you suspect a thermostat malfunction.

  1. Test the controls. Before you inspect the thermostat, check the HVAC controls first. Is the system on? Are the controls set (depending on the season) to cool or heat, as needed?
  2. Check the power. Sometimes homeowners presume there’s a system malfunction when it’s really a power issue. Make sure the system is plugged in to its power source. Make sure power is on in the home. Check the breaker to see if it’s been thrown during a power surge.
  3. Check the thermostat. Try setting the thermostat temperature 5 degrees higher for heating or 5 degrees lower for cooling to make sure it just hasn’t gotten warm or cool enough in the home for the system to turn on.
  4. Inspect the thermostat. If the thermostat doesn’t appear to be working right, turn off the system and remove the box. See if all the wires are connected. If you’re not sure how to reconnect loose wires, call an HVAC technician.
  5. Change batteries. If your thermostat takes batteries, try changing them.
  6. Change the fuse. A fuse is a long cylinder with filaments coming out of the ends. Good fuses are clear, while blown fuses look cloudy or dark.
  7. Replace the thermostat. Your best option may be to replace the thermostat if it’s old, out of date or malfunctioning. If you have an older model, such as an analog or a simple digital type, consider upgrading to a programmable thermostat. These can be set for efficient schedules that will save energy. A more expensive but very convenient option is the Wi-Fi thermostat, which can be operated remotely.
