Uncommon Heater Noises to Watch For

You might need heating repair and not know it. It is obvious if your heater stops working. However, there may be other signs that your heater is not doing a good job, or working efficiently, and you may not be aware of them. So, what are some of the other signs that your heater might need to be repaired?

Heaters make a wide variety of odd noises whenever they are about to break, or when they are not working efficiently.

Here are some of the more common unusual heater noises that are there to signal to you that your heater needs to be repaired.

Loud Banging or Booming

The key thing here is if your heater makes a loud gunshot-like sound when you turn it on. This can mean the heater has a gas build-up in it.

You shouldn’t ignore this sound, because the issue could crack the unit’s heat exchanger. If this happens, it is a dangerous situation and an expensive fix. Turn off the heater right away and call a repair person.

Metal Scraping Against Metal

A sound like metal scraping on metal isn’t good when it comes to a heater. It usually means there is an issue with the unit’s blower wheel.

The type of damage to the blower wheel may be a quick and easy fix, or more complex and expensive. Only a trained professional can tell you for sure.

A Rumbling Noise

Rumbling usually means your unit’s gas burners are dirty, or the pilot light needs to be fixed. These may seem like minor things, but they need to be addressed right away to make sure your heater continues to work well, safely, and efficiently.

A Rattling Noise

If your heater is rattling, it may mean a screw or panel is loose. You can probably determine this yourself, after turning off the unit. If it is neither, it may be a crack in the heat exchanger, which is a serious heater issue, as it can cause carbon monoxide to leak into your house.

This, of course, could kill anyone in the home, if you don’t notice, or if you don’t have a carbon monoxide detector. Turn off the heater and do not use it again until a professional repair person has fixed it.
