As the temperature in your Arlington, TN, home rises and falls, your furnace should alternate periods of action and rest. It should not remain on all the time. Here are a few possible reasons your furnace may have started running constantly:
Dirty Filter or Valves
As your furnace works, debris will find ways to gather inside of it. Eventually, if you do nothing to counteract this, that debris will gather on the system’s filter or in its critical valves, diminishing its performance. Once your system loses some of its ability to warm your home, it may react by working unremittingly.
This is why you must take care to remove debris from your furnace. We recommend replacing your filter at least every 90 days and scheduling maintenance services every year.
Malfunctioning Blower
Your furnace’s blower provides the power that spins the system’s fans. Therefore, this part is essential to generating airflow. If the blower malfunctions, your system won’t be able to push any of the warm air that it generates into your home.
If warm air doesn’t make it into your home, the indoor temperature won’t rise, and your thermostat will probably tell your furnace to keep working. The ultimate result may be a heating system that never shuts down.
Faulty Thermostat
It’s possible that your thermostat is ultimately to blame for your troubles. This device takes readings of the temperature in your home and then determines whether your thermostat should turn on. If it takes incorrect readings, your furnace may easily end up working when it doesn’t need to.
Alternatively, your thermostat may not be able to send the kinds of signals that will shut your furnace down. Finally, you may have inadvertently programmed the device at an excessively high temperature.
If your furnace doesn’t pass through regular cycles, it ‘ll be at great risk of incurring serious damage. To prevent this from happening, call Landmark Heating & Air Conditioning so we can fix your furnace that’s running constantly.
