If your heating system has been acting oddly as of late, then the first thing you should rightly suspect is the furnace or heat pump itself. However, it is possible that it isn’t the actual heating system at all, but rather something much more innocent sitting right on your wall. The thermostat is the brain of your HVAC system, and if it is having issues, then it can be responsible for many heating problems.

Frequent Short Cycling

Short cycling refers to the heating system turning on and then quickly turning off before the heating cycle is completed. This can be a sign of really serious issues in a heating system. Of course, it can also be caused by a thermostat sending the wrong signals. It tells the system to shut down early, and it shuts down. The alternative can also be true as well. A malfunctioning thermostat can force the heating system to run all the time as well.

Your Heat Doesn’t Turn On

Obviously, this is the primary worry of homeowners. If your heating system just doesn’t turn on at all, it must be broken. Yet, it could be that the thermostat just isn’t sending any signals to the heating system and telling it to turn on. The good news is that if this is your problem, replacing a thermostat is vastly cheaper than replacing your furnace.

Your Home Never Reaches the Right Temperature

Does it feel much cooler than the comfortable temperature you set your home to? It might be time to check if your home is actually reaching the temperature you set or not. In this case, there can actually be multiple thermostat issues at play. An obvious issue is that it is malfunctioning. Sometimes a heat anticipator can be stuck and causes temperature discrepancies. Another issue, particularly if you just got a new thermostat, is that it was either improperly installed or not installed in a good location. Essentially, if you installed a new thermostat too close to a heat vent or even something not involved like a toasty computer, it could cause it to read the wrong temperature.
