Your furnace keeps your home comfortable through the long Minnesota winters, so keeping up-to-date on maintenance is absolutely essential. The state Division of Energy Resources recommends furnace tune-ups once a year, but you may be wondering exactly what that really means and what it includes. Read on to learn everything you need to know about furnace tune-ups.

What Is a Furnace Tune-Up?

A furnace tune-up is a kind of routine maintenance that includes a full cleaning and inspection of all furnace components. If your HVAC contractors discovers problems during your tune-up, they can also make recommendations for repair or replacements at that time.

Why Do I Need a Furnace Tune-Up?

You need a furnace tune-up once a year for several important reasons. Your tune-up can do all of the following:

  • Improve operating efficiency, which can reduce your home heating costs
  • Institute preventive measures to avoid furnace malfunction and keep your family safe
  • Identify minor issues before they grow severe, preventing furnace failure later

Overall, a furnace tune-up simply makes good financial sense because it safeguards both your investment in the furnace and your family’s safety and comfort.

What Is Included in a Furnace Tune-Up?

A furnace tune-up can vary according to your particular needs, but in general you can expect it to cover all of the following.

  • Flue check: Your HVAC contractor examines the flue, the pipe, or the duct that exhaust gas moves through as it leaves your home. Your contractor clears away any blockages or obstructions to keep the flue clean.
  • Filter check: When your furnace filter is clogged, it prevents the furnace from heating your home efficiently. The dirt and debris forces your furnace to work too strenuously, leading to excess energy wastage and potentially furnace damage over time.
  • Electrical check: The electrical check covers all electrical components of the furnace including safety switches and wiring.
  • Motor check and adjustment: The motor check ensures that all parts of the blower assembly are functional. If needed, your HVAC contractor can lubricate the assembly and adjust speed.
  • Heat exchanger check: In the heat exchanger check, your HVAC contractor looks for cracks, rust buildup, or other signs of damage. A damaged heat exchanger can cause release of dangerous sulfur and carbon monoxide into your home, which means prompt repair or replacement is essential.
  • Interior furnace cleaning: In furnace cleaning, your HVAC contractor suctions dirt and debris out of the furnace. They clean other components including the burners, igniter, and blower motor thoroughly by hand.
  • Burner adjustment: Burner adjustment involves maximizing burner function for peak efficiency.
  • Gas pressure adjustment: Gas pressure adjustment allows for clean burning and excellent efficiency.
  • Ignition test: in the ignition test, your HVAC contractor ensures that the igniter switch works as it should. Because igniter switches don’t last forever, a slow-acting one might require replacement.

Your furnace tune-up may also include other tests and adjustments based on the type of furnace you have and whether you’re currently having any issues with it.

Finally, your HVAC technician restarts the furnace and then spends a few minutes evaluating its function to make sure there aren’t any issues. They’ll give you a furnace tune-up report that details everything they did.

If your HVAC contractor makes any recommendations regarding furnace repair or replacement, they can generally give you details about the projected cost and repair time after your tune-up. In many cases, your HVAC contractor can take care of simple furnace repairs on the spot, and if you need a major furnace repair or replacement right away, they can schedule you promptly.
