Some noises are welcome around your home: laughter, music, or even the sound of a good meal on the stove. Then there are other sounds that you don’t want to hear. This can include the sound of something going wrong with your heating unit.

Strange and concerning noises are often some of the earliest signs that you need to schedule heater repair in Columbia, SC. This applies to every type of heater, whether it is a furnace, heat pump, or another type of system. When you need heater repair, make sure to come to us for the professional service you need.

What Noises Are Normal?

Silent systems aren’t good, but neither are noisy ones. So is there an in-between with certain noises that are normal for your heater to hear? The answer is yes!

The most important noise that you may want to hear is the whoosh of warm air flowing from your heater and into your home. Aside from this, there are some other sounds that may be normal to hear, such as a brief amount of clicking at the start of the heating cycle or a small amount of crackling after the cycle ends.

But if your heater starts to make new, concerning noises, it means that you may need to schedule repairs.

Noises You Shouldn’t Hear From Your Heater

What noises do you not want to hear from your heating system? There is more than one! Here are some of the biggest culprits to keep your ears on the alert for:

  • Screeching: A screeching heater is one that is near impossible to ignore. This noise is often caused by a loose fan blade scraping around its housing or by a blower motor belt in need of lubrication.
  • Rattling: A rattling noise is often another sound that is caused by loose parts. It may be caused by some other problems though such as a cracked heat exchanger. In short, a rattling heater should be seen to as soon as possible.
  • Hissing: Don’t mistake a hissing noise for a whooshing of air. Hissing is usually caused by air being forced through a clogged filter or can be created by a leak in your ducts.
  • Clanging: Last but not least, don’t ignore that clanging noise. Clanging sounds usually follow rattling sounds that have gone unaddressed for too long. This is because this noise is caused by parts that have come fully free of their housing and are bouncing around in the system. This can cause some serious damage if not fixed quickly.

Has your heater become noisier than usual as of late? If so, we strongly suggest you reach out for professional service soon. The earlier that a noisy system is fixed by a trained technician the better off your home comfort will be. You don’t want a repair to become a replacement!
