Signs Your Furnace Needs to be Repaired or Replaced

Some of the most common warning signs that something is wrong with your furnace and it might need to be repaired or replaced are:

  1. Strange Noises: Furnaces aren't usually soundless; they emit a constant, low whirring noise. But if you ever notice your furnace suddenly making weird noises like banging or rattling, it means something is wrong.
  2. Uneven Heating: Some parts of your home will have different temperatures. For example, most basements are cooler than the top floor. However, your furnace should be able to heat similar environments equally. However, rooms on the top floor have noticeably different temperatures, indicating that your furnace isn't working correctly.
  3. Unusual Odors: Your furnace should be odorless. Strange smells, especially gas smells, are a bad sign and require immediate professional attention.
  4. High Energy Bills: If your heating bills are increasing, it could be a sign that your furnace is becoming less efficient.
  5. Frequent Cycling: Your furnace should automatically turn on when it senses your home is cold. Frequent cycling means your furnace turns on and off often, leaving the temperature in your home too hot or cold.
  6. Age: As a furnace ages, it often needs more repairs. Eventually, it will become so old that it's better to replace it than invest in more repairs.
  7. Visible Rust: If there's rust on your furnace, it's considered a serious issue as it can damage the furnace's internal parts and break it down.
  8. Frequent Repairs: A furnace that is starting to require constant repairs likely needs to be replaced instead.
  9. Little or No Heat: If your furnace is running but not producing enough heat—or any heat at all—it’s a clear indicator that something is wrong. This could point to issues with the blower motor, heat exchanger, or ignition system and should be addressed immediately to avoid a full breakdown.

Common Causes of Furnace Failure

Some of the most common reasons for furnace failure are:

  1. Dirty or Clogged Filters: Your furnace's filters must be cleaned regularly. As the filter gets dirtier, the furnace becomes less efficient.
  2. Pilot Light Problems: A dirty or clogged pilot light can prevent your furnace from turning on and working.
  3. Lack of Maintenance: Furnaces are large, complex machines that require regular maintenance to work efficiently.
  4. Wear and Tear: Regular wear and tear can, over time, break down parts of your furnace.
  5. Blocked Vents or Ductwork: Blocked vents can lead to many furnace problems, such as poor heating, increased energy consumption, and gas buildup, which can be life-threatening.
  6. Electrical Failures: Electrical failures in your furnace are dangerous and can cause the system to malfunction.
  7. Heat Exchanger Damage: A rusted, cracked, or broken exchanger is now a failed heat exchanger. If left unaddressed, heat exchanger damage can lead to several furnace issues, such as rust, water leaks, and soot buildup.

When You Need to Call a Professional

Some furnace issues can be tackled by homeowners, such as cleaning a filter. However, many furnace problems should be left to the professionals to reduce the risk of damage to your furnace or home. In particular, if your furnace smells of gas, produces no heat, short cycles, or makes unusual noises, leave these issues to be dealt with by an HVAC professional.
