I Think My Thermostat is Broken, but How Can I Tell?

One of the most essential pieces to the HVAC puzzle happens to be your thermostat. Whether it’s a standard model or a smart thermostat, these devices let you adjust how hot or cold you’d like your home to be. While this temperature-controlling accessory is usually the last item to break on your HVAC unit, it can fizzle out when you least expect it — and sometimes, you might not even know that it’s broken.

If you think your thermostat has seen better days, here are some signs to look for:

Ways to Get to the Root of Your Thermostat Problem

Attempt to Adjust the Temperature

For starters, the first sign of a non-functioning thermostat is that the device won’t adjust the temperature no matter how many times you fiddle with it over the course of a few hours. To see if this is the cause, you’ll want to either raise the temperature (or lower it) a few notches from your standard, daily temperature.

If you notice that after approximately 35 minutes that the temperature hasn’t changed, the device might need to be relocated in your home since it could be sensing the wrong temperature (i.e., placed too close near a window or an external door).

Examine the Power Source

Now, if you haven’t felt a difference in the temperature after adjusting your thermostat, then there may be something wrong with the power source itself. While most thermostats are hardwired to a house, some operate on batteries.

If you see that the power needs to be restored (or the battery needs to be replaced), tending to one of those two possibilities should fix it. However, if power is restored and the device still doesn’t function properly, then it’s time to seek a new thermostat.

Your Heater or A/C Constantly Runs or Won't Turn Off

If you notice that your heater or A/C won't turn off or is constantly running, this could be due to the fact that the wiring is either frayed or that your thermostat has been miscalibrated. One way of troubleshooting this is by trying to reset the thermostat to its default setting. If you still are experiencing problems, contact us for professional help!

How Long Should a Thermostat Last?

The average thermostat can last 10 years. When they reach 10 years of age and wear, it's time to replace them. Sensors, digital screens, and other problems associated with bad thermostats are common. When a thermostat malfunctions, your HVAC system may run continuously or not at all. Different thermostats have different settings. For the thermostat to function properly for many years, you must read the manual.
