Here are five signs you may need furnace repair:

  • Unusual Noises
  • Low Airflow
  • Strange Smells
  • Uneven Heating
  • High Energy Bills

Unfortunately, furnaces can break down unexpectedly — and when they do, it’s important that you know the signs so that you can get them repaired as soon as possible.

Unusual Noises

Unusual noises coming from your furnace should not be ignored, as they are usually a sign of something going wrong. Whether it’s the result of a broken fan belt or some loose parts rattling around the unit, having an expert take a look will help you identify what the problem is and how it can be fixed. Don’t wait too long to call in an experienced HVAC technician, as the longer you leave it, the more likely it is that your furnace could suffer serious damage — which can lead to sky-high repair costs down the road. Getting proper maintenance and repairs done when necessary will ensure that your furnace runs smoothly and efficiently for years to come.

Low Airflow

If the airflow from your vents is weaker than usual, then it could indicate that there is something wrong with your blower fan or blower motor. The fan may be clogged or the motor could be experiencing an electrical issue, both of which will require professional attention in order to be resolved properly.

Strange Smells

If you encounter a musty or chemical-like smell coming from your furnace, it signals the need for immediate attention. In the majority of circumstances, this can be attributed to an accumulation of dust inside the unit or a gas leak somewhere within the system; both scenarios are highly hazardous and demand expertise from a certified technician with experience in furnaces maintenance and repair. Although this could potentially cost you some money upfront, it will save you from possible catastrophic consequences – related either to health or financial implications – down the line. Therefore, if ever in doubt about suspicious odors coming out from your furnace, make sure that you do not take any risks and that you contact qualified assistance.

Uneven Heating

An even temperature throughout all rooms of your home should be expected when using your furnace — however, if this isn’t what you’re experiencing, then there could be an issue with the ductwork in certain areas of the house or there might even be issues with certain components of the unit itself (such as a worn out heat exchanger). A trained technician will be able to diagnose these issues quickly and accurately so that proper repairs can take place efficiently.

High Energy Bills

If you notice an unexpected increase in your energy bills during winter months when you use your heater more often than usual, then it could indicate that something is wrong with your furnace causing it to work harder than normal in order to heat up the home adequately. This could point towards several different issues — including clogged filters or faulty components — so having a technician inspect and repair the unit is definitely recommended if this occurs at any point during its lifespan.


As you can see, there are several different signs indicating that you may need to call for a furnace repair service right away before further damage can occur within the system itself or elsewhere in your home due to malfunctioning parts or other related issues arising from improper maintenance habits over time (such as neglecting regular filter changes). If any of these five problems occur while using your heater, don’t hesitate – contact a reputable furnace repair company today for fast repairs!

    After utilizing her heater after a lengthy vacation, my sister reported hearing strange noises from it. Thank you for talking about how strange noises coming from your furnace should not be disregarded because they typically indicate a problem. I’ll make sure to let her know about this and suggest that she get it checked out by a specialist to prevent problems from getting worse.
