The Mechanics of Your Fall Furnace Tune-upIt’s that time of year again, time to schedule a fall furnace tune-up. But are annual HVAC inspections really necessary? What does a tune-up involve, anyway? Are the tasks simple enough that a homeowner could do them himself? Here are the answers to these important questions.

Is a Fall Furnace Tune-up Necessary?

Scheduling preventative maintenance in the fall sets up the system for success. A tune-up greatly decreases the chance of a breakdown mid-season when you need your furnace most. It may not be utterly necessary, but just like going to the dentist every six months for a routine cleaning, a fall furnace tune-up is definitely recommended.

What Does a Fall Furnace Tune-up Entail?

It depends on the contractor and what your system requires. Sometimes the tune-up is minimal while other times it’s more comprehensive. A thorough tune-up is best.

The fall furnace tune-up basics you can expect your technician to perform include:

  • Check the vent system for leakage and blockage
  • Analyze combustion gases and ensure they closely match the unit’s specifications
  • Check the fresh air intake louvers and grills for blockage
  • Check burners for proper burner flame height, flame sense and ignition
  • Inspect the heat exchanger for corrosion and rust
  • Test the drainage system for leakage and blockage
  • Clean the blower wheel
  • Conduct an amp-draw test on the blower motor
  • Check the blower access door for a tight fit
  • Check wiring for corrosion or damage
  • Inspect the thermocouple
  • Clean and adjust the pilot light, if applicable
  • Check and change the filter
  • Tighten electrical connections
  • Lubricate all moving parts
  • Check the thermostat setting
  • Check belts for wear and tightness
  • Conduct a carbon monoxide test

Can a Homeowner Do a Fall Furnace Tune-up Himself?

If all you want to do is vacuum out the furnace, then sure, you can probably do the tune-up yourself. But if the contractor you hire does even half of the items on the list above, it’s worth it to have a professional do the work.
