Common Signs Your Commercial Furnace Needs Repair
A complete furnace breakdown is often preceded by warning signs. Addressing these symptoms early can prevent more extensive damage and costly emergency repairs. If your facility’s heating system is exhibiting any of the following issues, it’s time to schedule a professional inspection.
- Inconsistent or Uneven Heating: Are some offices freezing while others are uncomfortably warm? Cold spots throughout your building are a clear indicator that your furnace is struggling with air distribution, which could be caused by blower motor issues or problems within the ductwork.
- Unusual Noises: Commercial furnaces operate smoothly and relatively quietly. Any sudden banging, grinding, squealing, or popping sounds are abnormal and point to mechanical trouble. These noises can signify issues ranging from a loose blower belt to a failing motor or a serious internal component problem.
- Unexpected Increase in Utility Bills: A sudden, unexplained spike in your gas or electric bills is a red flag. It often means your furnace is working harder than it should to produce the same amount of heat, signaling a loss of efficiency due to a failing component or a clog in the system.
- Frequent Cycling: If your furnace turns on and off more frequently than usual, a condition known as short cycling, it’s a sign of a problem. This could be caused by a malfunctioning thermostat, a clogged filter restricting airflow, or an improperly sized unit.
- Ignition or Pilot Light Problems: For gas furnaces, a pilot light that won’t stay lit or an electronic ignitor that fails to start the burners is a common failure point that requires immediate professional service to ensure safe operation.
- Visible Wear and Tear: Cracks, rust, or corrosion on the furnace components, especially around the heat exchanger, are serious issues that demand immediate attention to prevent potential safety hazards like carbon monoxide leaks.
