Common Heater Sounds and Their Causes

Your furnace isn’t supposed to be noisy. It should not create a lot of sounds. If a furnace usually produces a lot of noise when people use it, then it will be obviously a lot difficult to sell them to clients. Though they are not completely silent, a properly working heat pump or furnace should operate quietly. The reason for this is that the process of moving or creating heat into your house should not necessarily involve any sound. Even an old furnace that is reaching the end of its life shouldn’t keep you up at night with loud sounds.  

Rather than attempting to deal with these sounds yourself, we are going to help you. We’re going to share with you some details as to what these sounds are and if you should be worried about them.  

If you do find issues with your furnace, do not hesitate to call a professional furnace repair in Spokane.  


Screeching sounds that are coming from your heater are the same as the types of sounds your vehicle may make. Screeching can be the result of a faulty belt that has to be fixed. Of course, it isn’t that big of a deal when you compare it to a booming or rattling sound that can become a safety threat. However, it is a huge deal in regard to the efficiency and effectiveness of your system. You need to have this belt fixed or replaced and have your heater serviced if you would like your furnace to properly operate.  


It will be extremely obvious not to worry about it if you would be hearing rattling coming from a bag of candy or children’s toys. However, rattling in equipment that isn’t supposed to be rattling is cause for alarm. Rattling shows that something is loose inside the unit. This is not really terrible at first. However, this can be extremely dangerous as time passes by since the possibility of your system breaking down is high. You have to get it repaired right away, whether it is a crack in the heat exchanger or a loose screw. 

Booming or Banging 

A furnace that’s booming can be suffering from an issue known as delayed ignition. This means that the gas that powers the heater is not igniting immediately and is coming out extremely slow. Because of this, gas will pool up inside and will eventually ignite in a tiny explosion. This is a bit risky since this tiny explosion can eventually crack the heat exchanger of the unit and cause flammable gas or carbon monoxide to leak inside your house. If you hear booming noises from your furnace, you have to deal with it right away by hiring a professional furnace repair company.  

Though these are not the only sounds that your heater can produce, they are some of the most popular ones and hard to deal with. As mentioned earlier, these issues can worsen over time if left ignored. Make sure you hire the right professionals right away.
