5 Common Furnace Problems

by Jamie Shaw

You need your furnace most during the cold season, and it would be frustrating if it failed to work. Servicing your furnace routinely should keep problems at bay. Unfortunately, you might experience issues with your furnace from time to time. This article will address some of these problems so that you call a furnace repair expert once you spot them.

Your Furnace Is Making Unusual Noises

Have you noticed a grinding or scraping sound from your furnace? Well, your furnace should always be quiet unless there is a serious issue. Sometimes the noise is just your furnace hinting it needs maintenance. All in all, you shouldn't ignore the noises because they could mean your furnace has one of the following problems:

  • Loose fittings
  • Duct contracting
  • Poorly lubricated motor
  • Broken blower wheel
  • Loose blower belt

Whatever the problem is, you should have an HVAC technician come to your house immediately before it escalates.

Dirty Air Filters

How often do you swap your furnace filters? Replacing your furnace filters regularly is a must. Dirty or clogged filters limit airflow, making your furnace overwork, which may lead to overheating the heat exchanger. If your furnace isn't producing enough heat and keeps going on and off, that indicates the airflow is restricted. You should consider replacing your filters as soon as possible.

Issues With the Pilot Light

Obviously, if your furnace's pilot light won't stay lit, it has a problem. Probably a pilot orifice is clogged, or the flame setting is very low. Contact a professional for furnace repair services to investigate the cause of this problem. If you attempt to relight the pilot light, always ensure the gas supply is off and wait for a few minutes. 

Your Furnace Doesn't Blow Any Air at All

Surprisingly, a malfunctioning furnace can run without blowing hot air. This could be a problem with a broken blower belt. Before attempting to replace your belt, always refer to your manual for instructions on how to go about it. If you cannot do it on your own, contact a professional for furnace repair services.

The Heat Exchanger Is Broken or Cracked

When there is no problem with the heat exchanger, your furnace runs efficiently and safely. However, failing to replace the air filters can cause the heat exchanger to crack due to overheating. 

Although spotting signs of a cracked heat exchanger can be difficult, the presence of soot in your furnace is one of them. If the heat exchanger is cracked, you have no choice but to replace it with another one.
