Do You Know The Four Common Causes Of Furnace Failure? Take Our Quiz

As we are in the coldest winter months, it’s important for homeowners to know how well their furnaces will perform before being asked to handle the heavy heating duties.Minneapolis Furnace Repair Man

A faulty furnace isn’t just a cash burner, it’s also a potential source for serious injury to your family. Before you fire up your furnace, consider having a Minneapolis furnace repair expert come out to determine whether you need to invest in repair or a whole new install.

If you think you understand how your furnace works, take our quiz to see if you know the 4 common reasons for furnace failure:

  1. How Many Times can a Furnace Cycle On and Off in a Year?
    Answer — up to 10,000 times. Combine this heavily repetitive cycling over years with the fact that the temperature rise can be as much as 900 degrees and you’ve just found one of the top causes for furnace failure – age.The best fix – consider purchasing a new furnace sooner rather than later – the new mandates from the Dept. of Energy call for mandatory installation of 90% efficiency furnaces as of May 1, 2013. This goes for new construction as well as retrofitting.You can still purchase 80% efficiency heaters until then, potentially saving on installment costs.
  2. What Does a Heat Exchanger Do?
    A gas furnace heat exchanger is heated by a blower fan from the furnace. The heat blowing over the warmed chamber funnels the heated air throughout the house and draws the combustible elements out through the chimney.The process of heating and cooling causes the heat exchanger to expand and contract, often causing another reason for furnace failure – heat exchanger cracks – a problem that calls for immediate furnace repair.The best fix – arrange for a Minneapolis furnace repair specialist to inspect your heat exchanger.
  3. What Causes Rust and Erosion in Heat Exchangers?
    The pilot flames in your furnace emit a powerful combination of carbon monoxide, nitrogen oxides, sulfur dioxides and water vapors. This supply of moisture and acidic gases corrodes metal heat exchangers and causes rusting of welded parts, the third leading cause of furnace failure.The best fix – here’s another reason to consider a new furnace, especially if yours uses a pilot light – a destructive, rust-causing element in older units.
  4. Are Furnace Failures Caused by Manufacturers or Installers?
    If you answered “both” you’re probably right. Many manufacturing mistakes have resulted in massive recalls – Carrier’s use of polymer (a plastic substance) when attaching fireboxes in the heat exchange system caused so many furnace failures the company paid $10,000,000 to settle a class action lawsuit.However, furnace install problems such as undersized duct work which causes more wear and tear from elevated temperatures can also end a furnace’s life prematurely.The best fix – check to see if your furnace model was involved in any product recalls by contacting your Minneapolis furnace repair experts.

It is important to note that a catastrophic failure of the heat exchanger can send a potentially dangerous mix of combustible products into the air your family breathes. Yet these problems can be avoided with regular furnace servicing, ideally with a local service company.

  2. Are heat exchanger cracks a common problem? I understand why they happen, the change in temperature causes the metal to expand and contract. How can you tell that’s the problem? Does the furnace stop altogether?
