A furnace can produce mild noises during normal operations. Usual furnace sounds don't always interfere with your peace of mind. However, if you hear sounds that aren't part of your day-to-day operations, your furnace may have damaged or faulty components. Here is an overview of some weird sounds that call for heating repairs.

Loud Bangs

A gas furnace with dirty burners allows gasses to accumulate. When the gas becomes excessive, you hear loud banks during startup. You will need a professional to clean the dirty burners. Otherwise, your heat exchanger could damage and cause significant furnace repair or replacement.

Knocks or Clangs

Your pipes and ducts expand during startup to heat your home and could generate knocks and clangs. Nonetheless, you could have loose components in the motor or blower assembly if you hear the sounds when the furnace runs. Seek furnace repairs before the loose part breaks and causes extensive damage to your furnace.

Booms

Booms could range from something small like dirty burners to a bigger problem like damaged gas valves. The expansion and contraction of air ducts also cause loud boom sounds. Also, grime and build-up in the combustion chambers cause boom sounds. Only a qualified technician can pinpoint the root problem and offer the necessary furnace repair.

Rumbles

Call a heating repair technician to identify and resolve the problem if your furnace completes a cycle but still notices rumble sounds. The reason could be faulty banners or flame sensors, fuel that burns after the burners have shut down, or pilot light problems. If you overlook rumble noises from your furnace, you put your family at risk of carbon monoxide poisoning.

Screeches

Loud screeches usually come from problems in the belt or motor bearing. For example, the belt that connects the motor to the fan could slip or crack and generate screeches. Dry motor bearings, too, could also create the screeching sound. Furnace repair to resolve the problem involves repairing the belts or lubricating the bearings.

Rattles

A rattle could indicate that you have a cracked heat exchanger. In such a scenario, carbon monoxide food leaks into your home, so immediate furnace repair is crucial. A cracked heat exchanger may also call for replacement. Yet, you shouldn't panic because clatter sounds could also mean you have loose components. The only way to find out is to set your furnace repair appointment to verify the root of the problem and identify the way forward.

Conclusion

Schedule a prompt heating repair for any of the above sounds. Also, note that some sounds happen due to a lack of maintenance and not major problems. Once your trusted heating repair technician resolves the underlying problem, you can get advice on prevention measures to prevent the sounds' reoccurrence.
