6 Sounds Your Heater Should Not Make

Oct 9

No one likes a noisy house. But when the source of that noise is your heater, it can be more than just a nuisance—it can be cause for alarm. That's because strange sounds coming from your heating system could be an indication that something is wrong. And that noise is trying to tell you something. Maybe your system needs heating repair Tulsa OK?

In this blog post, we'll go over six of the most common sounds your heater might make—and what they mean. Armed with this knowledge, you'll be able to determine whether you need to call in heating repair Sapulpa OK or if you can handle the problem on your own. So, let's get started!

  1. Banging or Popping

If you hear banging or popping coming from your heater, it's likely due to sediment build-up in the tank. Sediment can cause your heater to overheat, which can lead to a whole host of other problems. When sediment accumulates, it can restrict the flow of water through the pipes, causing water to back up and put pressure on the tank walls.

The good news is that this is an easy fix. Simply drain the sediment from the tank and you should be good as new.

  1. Hissing or Whistling

Hissing usually indicates that there's a gas leak—which is definitely something you'll want to get fixed right away. If you smell gas along with hearing the hissing noise, evacuate your home immediately and call your gas company. 

Also, a hissing or whistling noise from your heater may indicate a hole or crack in one of the pipes. As pressurized water rushes through the cracked pipe, it causes a high-pitched hissing sound. Ignoring this problem will only make it worse—eventually, the leak will cause water damage and may even lead to flooding. So, if you hear this sound coming from your heater, be sure to call a plumber right away.

  1. Booming

Booming sounds are generally caused by waterlogged dirt or debris in the burner assembly. The best way to clean out the burner assembly is to remove it from the unit and then use compressed air to clear out any blockages.

  1. Screeching

If your heater starts making a screeching noise, it's likely because one of the bearings has gone bad. 

The bearings help keep the blower wheel in place, so when they fail, the wheel starts to rub against other components in the system—hence the screeching sound. Replacing the bearings is a fairly simple and inexpensive repair that any HVAC technician can handle.

It can also be due to a loose blower belt. The belt can usually be tightened by adjusting the bolts that hold it in place—but if it's worn out, you'll need to replace it entirely.

  1. Humming

A humming noise coming from your furnace is usually caused by an electrical problem—specifically, loose wiring. When wires are loose, they create friction as they rub against other components in the system (kind of like two pieces of metal grinding together). This friction creates heat, which causes the wires to expand and contract—and that's what produces that distinctive humming sound.

If you hear this coming from your furnace, it's best to call an electrician or a professional in heating repair Sapulpa OK right away as loose wiring can be extremely dangerous and potentially lead to fires.

  1. Rattling

Rattling sounds could be due to anything from loose paneling on your unit to debris caught in the blower blades. In either case, simply remove whatever is causing the rattling noise and dispose of it properly (i.e., don't just leave it inside your heater!).

With that taken care of, your unit should run smoothly once again.
