Your furnace is essential to your home or workplace, especially during the colder months. It keeps you and your family warm and comfortable, so ensuring it functions properly is important. However, sometimes furnaces can start failing without any noticeable signs or sounds. To prevent unexpected breakdowns and ensure the comfort of your home, it’s essential to be aware of the silent signs that your furnace might be in trouble.


In this blog post, we’ll explore eight subtle indicators that your furnace is failing and why contacting GE Home Services at the first hint of trouble is imperative. We specialize in furnace repair in Phoenix and Tempe, AZ, providing top-notch service to keep your furnace running smoothly.


Don’t Get Left in the Cold: Recognize the 8 Silent Signs Your Furnace is Failing Today!

Corrosion and Rust

Corrosion and rust are not to be underestimated when indicating a failing furnace. These signs should not be ignored as they suggest the presence of moisture where it shouldn’t be, potentially resulting in more significant issues in the future. If you notice any visible signs of rust or corrosion on your furnace, it’s strongly advised to promptly seek the assistance of a professional technician to address the matter and prevent any further complications.

Strange Odors

Unpleasant odors emanating from your furnace could be a cause for concern. Detecting a musty or burning odor might be a sign of mold growth, a clogged air filter, or even an electrical issue. Foul odors should never be ignored, as they can indicate potential safety hazards. GE Home Services can identify the root cause of the odor and perform the necessary repairs to keep your furnace running smoothly.

Yellow or Flickering Flame

A healthy furnace flame should burn a steady blue. If you observe a yellow or flickering flame, it could be a sign of incomplete combustion, which may produce harmful carbon monoxide. This color change could be due to issues with the burners or other internal components. Since carbon monoxide is odorless and colorless, any suspicion of a faulty furnace should be addressed immediately to avoid serious health risks.

Visible Soot Around Vents

Soot around heating vents is a red flag that your furnace might be experiencing combustion problems. Soot is a byproduct of incomplete combustion and can indicate issues such as a clogged burner or a malfunctioning heat exchanger. Ignoring this sign can lead to poor indoor air quality and pose health risks. 

Frequent Repairs

A well-maintained furnace should not require frequent repairs. If you find yourself constantly calling a technician for repairs, it could be a sign that your furnace is reaching the end of its lifespan. Continuing to repair an old furnace can end up costing more in the long run and may not provide reliable heating when needed the most.

Poor Air Quality

If you notice an increase in dust, dirt, or rust particles in the air, it could be a sign your furnace is not properly filtering the air. This can lead to health issues, especially for those with asthma or allergies. Don’t ignore this sign; get your furnace inspected by a professional.

Age of the Furnace

Even if your furnace is functioning, its age can be a silent indicator of potential problems. The typical lifespan of furnaces generally ranges from 15 to 20 years. If your furnace is approaching or has surpassed this age range, it’s wise to consider a replacement. Investing in a new, energy-efficient furnace ensures reliable heating and reduces energy consumption, saving you money in the long run.

Blowing Cold Air

It goes without saying, but if your furnace is blowing out cold air instead of warm, it’s a clear sign that something is wrong. This could be due to a malfunctioning thermostat, faulty blower motor, or other issues within the furnace. Troubleshooting and repairing these problems should be left to trained technicians for safety and efficiency.
