How To Know If A Thermostat Is Not Working?

You can have the most efficient and technologically advanced heating and cooling systems available, but your Glenwood Springs, Aspen, or Vail, CO home still won’t be comfortable if that little box on the wall isn’t working correctly. By “little box” Climate Control Company is referring to your thermostat. Sometimes HVAC problems have nothing to do with the furnace, air conditioner, or heat pump but rather the device that tells them what to do. 


  • Thermostat is unresponsive or has no power—When the display is dark it could mean a problem with the wiring, but also remember some thermostats have batteries that need to be replaced. Try replacing them before calling for professional help. If there is absolutely no response from the HVAC systems when you adjust the thermostat setting, you should suspect a wiring defect and call for professional help.
  • Temperature doesn’t match setting—This is a more subtle indication of a broken thermostat. While it’s still communicating with your heating and cooling systems, something has gone wrong in the process, so the two devices are no longer calibrated. Just remember that if you have a zoned system, different rooms can be set to different temperatures. 
  • HVAC Systems seem to run constantly—This can also be a problem with deteriorating or frayed wiring, but there is often a simpler reason. Double check to make sure the fan is set to “Auto”. If this has been changed to the “ON” position, the fan will run all the time instead of just during the heating or cooling cycle.


Let’s face the truth: Some people love today’s digital technology, and some people hate it. That includes thermostats. Today’s programmable and smart thermostats are wonderful at giving the homeowner more control of the HVAC systems, but for some they can be confusing to program and operate. If you suspect a problem with the thermostat settings in your Glenwood Springs, Aspen, or Vail, CO home, get out the owner’s manual. Carefully go through each step to make sure it’s programmed properly. If you are confused and just not sure how to do it correctly, don’t be afraid to ask for help. A thermostat inspection and diagnostic check is always part of annual heating and cooling maintenance by Climate Control Company technicians. Call now to schedule your appointment.
