Aaron came to service my AC unit today and I was totally impressed. He was very professional, courteous and extremely knowledgeable and an obvious great work ethic. He made me feel very comfortable with him doing the things that needed to be done. The outside unit wasn’t the easiest access but he went above and beyond with no complaints. I will only use this company and Aaron for my future service needs! Thank you Aaron for a great job!

Furnace Not Working? Here’s What You Need to Know

If your furnace is acting up, it’s crucial to address the issue before it escalates into a costly repair. Here are some common symptoms that indicate your furnace may not be working properly:

  • Keeps running continuously without shutting off.
  • Keeps going out, leaving your home without heat.
  • Turns on and off repeatedly (short cycling).
  • Leaking water around the unit.
  • Buzzing or knocking noises, indicating mechanical problems.
  • No sound or unusually quiet, a sign of a failed component.
  • Sounds like a jet engine, suggesting airflow issues.
  • Yellow flame instead of blue, a sign of incomplete combustion.
  • Not all burners igniting, leading to uneven heating.
  • Pilot light is out, preventing the furnace from starting.

If you notice any of these symptoms, it’s time to schedule a professional inspection.

Why Is This Happening? Common Furnace Issues

Several components of your furnace can malfunction, causing it to stop working. Here are some of the most common causes of furnace problems:

  1. Igniter or Electronic Ignition Failure
    Without a properly functioning igniter, your furnace cannot light the burners.

  2. Fan Motor Problems
    A failing or failed fan motor prevents proper airflow through your system.

  3. Thermocouple Failure
    This safety device can malfunction, cutting off the gas supply even if it’s not necessary.

  4. Wiring Issues
    Faulty thermostat wiring can cause intermittent or no communication with your furnace.

  5. Control Board Failure
    The control board governs your furnace’s operations. A failure can disrupt the entire system.

  6. Exhaust Vent Problems
    A damaged, disconnected, or blocked exhaust vent cap can cause dangerous gases to build up.

  7. Flame Sensor Malfunction
    A dirty or faulty flame sensor can prevent your furnace from staying lit.
