The last thing you want to experience is a furnace breakdown that leaves you without heat on one of the coldest nights of the season. However, many homeowners struggle with one thing: when should they call for service? While there are all sorts of warning signs a homeowner can notice, one of the most common is when the furnace begins making odd sounds. The average homeowner may not think all that much about them, but shrugging them off may prove to be an unwise move.

4 Odd Furnace Sounds

While your furnace can hit all sorts of notes, we find these 4 sounds are generally the most common. Here is a brief overview:

  1. Booming: If your furnace is making a booming noise when it starts up, it hints at a problem with the furnace’s ignition. This problem can actually end up causing severe damage to your furnace and burning you as well if you do not take care of it right away. A gas valve opens and sends gas to the burners of the furnace in order to ignite it. If the gas is not ignited immediately, the gas will build up in the furnace and build up until it finally ignites and causes flames and explosion in your furnace.
  2. Cracking: If you are hearing clicking noises coming from your furnace, it could be indicative of a wide range of problems. It may indicate that the spark igniter of your furnace is attempting to ignite the burners or pilot light, but it is not working. In order for your furnace to properly operate, after the thermostat requests heat, the ignition system must be energized. Only then can the gas valve open, the furnace burners light up, and the furnace blower come on and start blowing hot air into your home. If there is a malfunction in the ignition system energizing, there’s likely something wrong with the system. There could also be issues with the thermocouple, which is a flame sensor that opens a gas valve to the furnace burners when it detects a pilot flame. It may also mean the pilot flame is not striking the thermocouple the right way. If the flame sensor does not sense that the flame is lit, the spark ignitor will simply spark over and over until it gives up.
  3. Screeching: If you hear screeching noises coming from your furnace, this will most likely indicate that there is an issue with the motor bearing or the belt. This may not be as concerning as other noises, but if it is not treated immediately, it may result in you spending more money on furnace repair service.
  4. Rattling: If you hear a loud rattling noise coming from your furnace, it could actually mean that part of it is coming loose. It could mean components are banging against each other. It could even be a loose screw. Often, a rattling noise can be rectified by simply tightening up the cover panels. However, it is also possible that a rattling noise can mean that there is a leak in your heat exchanger. This can also indicate carbon monoxide entering your home.
