How to troubleshoot a malfunctioning heating system

If your furnace heat is low try the following troubleshooting steps:

  • Insure nothing is on the way of warm air flow.
  • Verify the thermostat set up is properly done.
  • Raise temperature 5 degrees up then wait for a couple of minutes.
  • The room heating registers have to be open.
  • If the filter is dirty replace it

If these simple steps don’t work; either the blower isn’t working properly or the system is out of balance.
