Signs Of Furnace Failure

30 August 2021

Heating systems don't last forever, and if your furnace breaks down, especially during the winter season, you'll have trouble keeping your house warm. A furnace breakdown during the cold months is every homeowner's worst nightmare. 

Avoid such situations by looking for signs of furnace failure. These include the following.

Difficulty Turning on the Unit

Are you having trouble starting your furnace? This is common, especially if you have an older furnace. If starting is not the only issue, consider replacing the entire unit. However, if it works perfectly except for the difficulty when starting the unit, consider furnace repair. Consult HVAC contractors for help resolving the issue. The malfunctions can often be remedied by replacing the affected part. 

Persistent Loud Noises 

Furnace systems aren't known for their silent operation, but they're also not too loud. If your furnace is producing a persistent loud noise, that is a sign of a serious problem. Listen to the noise carefully, as you'll need to describe it to your HVAC contractor. Pay attention to the noise because it might give you an indication of the problem. For example, banging or groaning noises often indicate loose internal parts. 

Frequent Repairs 

If your furnace breaks down, it makes sense that you would repair it. However, if the furnace repairs become frequent, it's time to reevaluate your repair spending. If you're spending a significant amount every few months to repair your furnace, consider upgrading to a newer furnace. 

Increased spending on furnace repairs often means your furnace is about to break down completely. Consult your HVAC contractor to help you choose the ideal replacement based on your heating needs. 

Cold Spots 

Your furnace should heat your home evenly; thus, cold and hot spots around your house should be cause for concern. Typically, such problems are associated with malfunctioning motors, pilot lights, or heat exchangers. 

This is among the few signs that you can't miss. Contact your HVAC contractor and have them inspect your heating components for any issues. 

Carbon Monoxide Leak 

It's hard to spot a carbon monoxide leak since it's odorless and colorless. If your furnace is leaking carbon monoxide, contact professionals to seal the leak. Since the gas is odorless and colorless, you'll need to install carbon monoxide detectors to detect a leak. Also, understand the signs of carbon monoxide poisoning as a way to detect exposure to the gas. 

If you feel fatigued, have chest pains, or are dizzy, nauseated, confused, and impaired, it could be carbon monoxide exposure. Other signs of a leaky furnace include sooty stains around the furnace, an overheating smell, and heavy condensation on windows near the furnace. If you suspect a carbon monoxide leak, contact HVAC contractors immediately to inspect the unit and conduct repairs.
