These Eerie Sounds From a Heater Mean Trouble

After a summer of heat, the cool evenings and mornings that we see during fall are a welcome change. As things slowly but surely start to cool down, it means that we will be switching from cooling to heating.

Maybe you’ve already had to start using the heater in the morning, just to get everyone out of bed and started for the day. If that is the case though you may have started to notice that your heating system is making some odd noises. We can explain those noises and explain why they should prompt you to get your heating system repaired ASAP.

Heater Making Some Chilling Sounds? Here’s What They Might Mean

If you hear any of the following sounds, make sure to reach out to our team of experts to get your heater checked out. No matter what type of heater you have in your home, new and concerning noises are always a sign of trouble.

  • Hissing: Hissing from your heater can be caused by a range of problems. In the best case, this sound may be the result of an extremely dirty filter that needs to be changed out (something you can do yourself). However, if this isn’t the cause of the noise, then you may have a bigger problem on your hands. Hissing can also be caused by issues like a refrigerant leak in your heat pump or a cracked heat exchanger in a furnace. We’d advise having a professional check out and address this problem before it causes a breakdown.
  • Screeching: When your heater started to screech or scream at you, it isn’t because it is trying to talk back. This is a noise that is created when metal scrapes or drags against metal. Aside from sounding bad, this is also bad news for your heater’s well-being. Screeching can be a sign of a dry blower motor belt or dry motor bearings. It may even indicate that you have a loose fan blade scraping around its metal housing. The longer the issues causing this noise goes on, the worse the damage is likely to be so make sure to get it checked quickly.
  • Silence: Sometimes silence can be too silent such as when your toddler gets too quiet or when your heater makes too little noise. This is because the lack of noise can actually be a sign of a malfunctioning system. If your home is cold and your heater is supposed to be running, that silence means that the heater either isn’t getting its orders right or isn’t able to accomplish its task.
