Signs Your Gas Furnace Is Failing And Needs Urgent Repairs

Posted on

Winter's freezing temperatures can pierce even the most well-insulated homes, which is why a heating system is vital for homes in regions that experience harsh winters.  

If you rely on a gas furnace to keep your home warm and cozy during the cold months, you expect it to work reliably and efficiently. Unfortunately, furnace malfunction can occur at any time, leaving your family at the mercy of winter's biting cold. 

Watching out for early signs of furnace trouble and taking immediate corrective action can help you salvage the situation and avoid expensive heating repairs. Get your gas furnace diagnosed and repaired if you notice the following trouble signs.

Inadequate Heat

The primary purpose of any heating installation is to ensure sufficient distribution of heat in a building. If you're getting inadequate heat from your furnace, that's a sign it is in need of repair. Place the back of your hand against the air vents in each room to determine if you're experiencing low airflow.

Several factors can lead to poor heating, but the main culprits include the following:

  • Clogged filters
  • Dirty air ducts and vents
  • Faulty blower 
  • Damaged heat exchanger
  • Incorrect thermostat setting

The furnace repair needed to restore comfort in your home will depend on the cause of the problem. Quick and simple fixes like filter replacements are pretty inexpensive, but you may need to pay more for air duct cleaning or a new heat exchanger.

Weird Furnace Noises

It's not unusual for furnaces to make some noise when in use. Furnaces normally produce banging and popping sounds as the air ducts expand and contract with temperature changes.

That said, unusually loud and frequent banging and popping, as well as other strange noises, can be an indication that something is wrong with your furnace. For example, a scraping or grinding noise can be pretty alarming because it implies that metal parts might be rubbing against each other. The best way to address the issue is to let a heating specialist inspect your furnace to find the source of the noise and remedy it.

Unusual Furnace Odors

Your furnace may smell like the fuel it uses when you turn it on at the start of the heating season. However, the smell should go away after a while. If the gas smell from your furnace doesn't disappear or you notice a burning, oily, or musty smell coming from it, you might be facing a big problem. A professional can investigate the source of the smell and help you address it.

While there are some gas furnace repairs you can make yourself, heating malfunction may be an indication of underlying problems that only a professional can find and correct. It's best to let an HVAC specialist check your heating unit even if you manage to get it running smoothly again.
