Signs You Need Immediate Heating Attention

• Blowing Cold or Lukewarm Air: Indicates ignition failure, clogged gas orifices, or a tripped high-limit switch.
• Continuous Short Cycling: System runs for 60 seconds and shuts off repeatedly, often due to severe airflow restriction or overheating.
• Unusual Bangs, Squeals, or Rattles: Suggests loose blower wheels, worn motor bearings, or delayed ignition gas buildup.
