Once your furnace goes on and off too frequently, set your heat anticipator nearer to the “longer” setting. Even if you might not see the improvement of the heat for a few hours, you still need to wait for some time. If necessary, readjust it.

  • Confirm that nothing is obstructing the airflow. 
  • Ensure that you set the thermostat to “heat.” Try to raise the temperature up to 5° and wait for some time to check if it improves.  
  • If it’s necessary to replace it, put in a new filter. 

An outdated filter is among the most typical issues that furnaces face. Because of that, make sure to have your filters changed regularly in order to prevent any buildup of dust, dirt, and other contaminants and to repair your furnace.
