Even the most reliable heaters can encounter issues over time, and recognizing when your heating system requires attention is vital to ensure your home stays cozy. At Technic Air Mechanical, we understand the importance of a well-functioning heater, and we’re here to guide you on how to identify when it’s time for furnace repair in Aurora, CO.


Your heater, when operating smoothly, is relatively quiet. But if you start hearing unusual noises emanating from your system, it’s a clear indication that something isn’t quite right. Clanging, banging, or squealing sounds can all point to underlying problems that require prompt attention.

While not all noises are cause for immediate concern, being able to differentiate between normal and abnormal sounds is crucial. Here’s what to listen for:

  • Banging or Clanging: These sounds can suggest loose or damaged components within your heater, such as a broken blower wheel or motor mount. Neglecting this issue can lead to more extensive damage.
  • Squealing or Screeching: High-pitched noises often signal issues with the blower motor or fan. These components play a vital role in distributing warm air throughout your home.
  • Rattling: Loose or unsecured parts may result in a rattling noise. It’s essential to address these issues promptly to prevent further damage and increased repair costs.


Another valuable tool for recognizing heater problems is your sense of smell. While it’s common for heaters to emit a faint, earthy odor when first fired up for the season, certain smells are a cause for concern. Being able to distinguish between normal and abnormal odors can help you decide when to seek professional assistance:

  • Burning Odors: A faint, dusty smell when you first use your heater after a period of inactivity is normal. However, if you notice a strong, acrid burning odor, it’s time to turn off the heater immediately and contact Technic Air Mechanical. This smell could indicate overheating, electrical issues, or even a foreign object near the heating elements.
  • Musty or Moldy Odors: These odors can suggest mold or mildew growth within your heating system or ductwork, which can impact indoor air quality and your family’s health.


The pilot light on your heater is like a silent communicator, indicating the status of your heating system. A steady, blue pilot light is what you want to see. But if it turns yellow, this is a sign that something’s amiss.

  • Yellow Pilot Light: A yellow pilot light can indicate incomplete combustion, which is not only inefficient but can also release harmful carbon monoxide into your home. If you observe this, it’s imperative to contact a professional for furnace repair immediately.


One of the most noticeable signs that your heater may need repair is uneven heating throughout your home. It’s not uncommon to have some temperature variation due to factors like room layout and insulation, but extreme disparities are a cause for concern:

  • Cold Spots: If certain areas in your home consistently feel much colder than others, your heater may not be distributing heat effectively. This can result from issues with the blower fan, ductwork, or even a malfunctioning thermostat.
  • Inefficient Heating: A heater that’s running longer than usual without adequately warming your home is likely suffering from efficiency problems. This can lead to increased energy bills and discomfort for your family.

Your heater is a critical component of your home, and recognizing when it requires repair is essential to maintain your comfort and safety.
