Ideally, a furnace should operate efficiently and smoothly without any disruption. At the same time, it should make your place comfortable. However, it is not always the case, and an appliance tends to make certain noises as it ages.

Do you wonder why your furnace is making loud noise?

The reason for noise could be anything from loose ducts to a worn-out fan belt. It’s important to determine the source of the noise to see whether it is a normal sound or not. If it’s not a normal heater noise, something is wrong with your heating system.

Why Does My Furnace Make A Noise?

Here are some of the reasons why your furnace might be making odd noises.

  • Cracked heat exchanger
  • Loose ducts
  • Worn out fan belt
  • A loose blower fan
  • Fuel ignition problem
  • Dust build-up

It’s usual for  your heating system to make certain noises, depending on the problem. Below, we’ve listed some of the noises and their causes.

1) Screeching

If there is a problem with a belt, bearing or motor, your furnace is more likely to make a kind of screeching noise. Screeching noise can be super costly if left unattended. It’s recommended to get expert advice immediately. Otherwise, it may lead to more costly repairs.

2) Chirping

If your heater has not been in use for  a long while, this sound is more likely to occur. There is nothing to worry about this sound because it will stop once your heating system has warmed up. If the problem persists, a professional technician can help diagnose your noisy furnace.

3) Knocking

A knocking sound is a signal that your heating system needs a service or repair. You need to immediately turn off your heating system and contact a heater technician. A damaged belt or bad bearings are the two common causes of knocking sound.

4) Boom or Bang

A boom or band noise could be because of two things. If there is a delayed gas ignition, it may cause such noises. Because of this, gas will tend to build up in a furnace over time. For that reason, it leads to mini-explosion once the gas finally ignites. Such an explosion can harm your furnace and the repair could be very costly. Secondly, expanding and contracting metal ductwork can also make a similar noise. In either case, it is recommended to hire a professional furnace technician like Quick Air.
