Commercial Oil Furnace FAQ for Middletown Business Owners

  • Common signs that indicate your commercial oil furnace may need repair include:

    • Inconsistent Heating – Uneven or fluctuating temperatures throughout your space can signal furnace issues.
    • Strange Odors – Unusual smells, such as burning or fuel-like scents, are warning signs of potential problems.
    • Excessive Noise – Loud banging, rattling, or popping sounds often indicate mechanical defects.
    • Sudden Shutdowns – The furnace unexpectedly turning off can point to electrical or safety concerns.
    • Yellow or Flickering Flame – A healthy oil furnace flame should be steady and blue; a yellow flame suggests combustion problems.
    • Increased Energy Bills – A sudden rise in heating costs often means your furnace is working harder due to inefficiencies.
    • Frequent Cycling – Turning on and off more often than usual stresses the system and may signal thermostat or airflow issues.

    Recognizing these signs early allows for prompt repairs that help avoid costly downtime and maintain a comfortable environment.
