Diagnosing Furnace Noises


Your home's furnace is probably not perfectly quiet, but it shouldn't begin making any exceptionally loud or alarming noises. A new noise is usually indicative of a problem. The following troubleshooting guide can help you diagnose the causes of many furnace noises a technician from a company like http://rbincorporated.com/ can properly fix the problem.

Banging Sounds

These noises typically only occur in water systems, such as in homes with radiators or boiler-driven heat. The cause is generally caused by air bubbles in the pipes. If the radiators are steam-driven, it can also be caused by improper venting. Having an inspection the radiators drained at the beginning of the heating season can help flush out any air bubbles. Steam issues occur when the radiators aren't leveled properly at installation. This is something that an HVAC technician can remedy by reinstalling the radiator at the correct slope.

Buzzing or Vibrating Noises

This is caused by a system that vibrates something in the main location, typically its outer casing. Occasionally the sound is caused by the furnace fan vibrating the connecting ductwork. While not indicative of any major problems, it can be annoying. Your HVAC tech can install an anti-vibration pad or dampener on the exterior of the unit that will eliminate this problem.

High-Pitched Buzz or Squeal

This is most likely caused by an issue with the blower fan. The fan maybe going out or it may simply need to be lubricated. In some cases it may also indicate issues with the motor. Generally, high-pitched noises will always be generated by moving parts, and often the root of the problem is a worn part or poor lubrication. An annual inspection and furnace tune-up can prevent these problems before they reach the stage of making noise. In some cases you may need to have the blower fan replaced if it is wearing out completely.

Loud Bangs

These noises in an oil burning furnace can indicate a major problem. They occur when fuel accumulates on the burner, and then burns off at once during the next ignition cycle. This rapid combustion leads to the noise. It can also result in an explosion. If you hear a loud bang from your furnace, turn it off until you can have it professionally inspected. Smaller bangs from non-oil burning furnaces are indicative of a multitude of issues, but generally nothing severe. Loose parts or a failing fan or blower are the most common causes.
