Furnace Annual Maintenance by IndoorAire

One of the best ways to ensure that your furnace will keep working efficiently all winter long is to have an annual maintenance check. Inspections pay for themselves through improved energy efficiency, which saves money on utility bills, and a longer-lasting furnace.

You know what happens to cars that don't get their oil changed, teeth that don't get brushed, lawns that don't get weeded: costly repairs. Same thing if you let your furnace go.

IndoorAire's furnace maintenance checklist:

  1. Clean and inspect heat exchanger (see video)
  2. Adjust belt
  3. Oil motor
  4. Clean or adjust pilot
  5. Clean flame sensor
  6. Check thermocouple
  7. Check gas valve
  8. Clean burners
  9. Check thermostat operation
  10. Inspect filter
  11. Inspect drain
  12. Check temperature rise
  13. Check air flow

Cracked heat exchanger? Here's why it needs attention.

A cracked heat exchanger eventually causes damage to your furnace including

  • improper burning
  • flame roll-out
  • soot build-up
  • failed ignition

A heat exchanger crack may not initially cause a dramatic build-up of CO in your home. However, cracks get larger over time and it is impossible to predict exactly when the furnace will pose a serious threat.
