Answer: Why Is My HVAC System Making Loud Noises?
Loud or unusual noises from your HVAC system indicate underlying problems that should not be ignored. Banging or popping sounds in a furnace may indicate a delayed ignition or ductwork expansion. Screeching or squealing noises often point to bearing wear in the blower motor or circulation pump. Rumbling in a water heater typically means sediment buildup. Banging in a boiler may indicate trapped air or kettling from limescale. Rattling could be loose panels or components. Each type of noise points to a different cause, and professional diagnosis is recommended to prevent more serious damage.
