5 Indications Your Furnace Needs To Be Repaired

As temperatures began to drop this winter season, it's only natural to consider the heating system of your home. If your furnace is not operating properly, it can cause the climate inside your house to be quite uncomfortable. Still, there are usually warning signs that indicate a furnace needs to be repaired. Here are a few of them:

Is your furnace making unusual sounds?

If you notice odd noises, such as groanings or banging sounds, coming from your furnace, there may be a problem. A furnace that is functioning normally typically operates with a quiet hum. Other loud noises can indicate that a furnace component is loose or even missing.

Is your furnace unresponsive to changes in your thermostat setting?

If you are adjusting your thermostat and there is no response from your furnace, the thermostat could be broken. However, there could also be other issues, such as a leaky duct or a pilot light that is no longer lit.

Is your electric bill higher than normal?

When you compare last year's electric bill to this year's, is there a significant difference even though there were no major differences in the weather? An electric bill that is significantly higher than normal may indicate that your furnace is no longer operating at its usual level of efficiency. It is best to have it checked by a furnace repair specialist to determine and correct the cause of the inefficiency.

Is your pilot light burning yellow?

If your pilot flame is usually blue but is now yellow, it can indicate that carbon monoxide is present. Elevated levels of carbon monoxide are often caused by problems with inadequate combustion. Still, visual inspection is often not sufficient to determine a carbon monoxide problem. It is best to have your home tested for unsafe levels of this colorless, odorless gas. Since this poisonous gas is not easily detected by your senses, be sure to have your system professionally analyzed as soon as possible.

Does your furnace blower turn off unexpectedly?

If your furnace blower does not continue in an on position or periodically shuts off without notice, there could be a problem with your pilot, your wiring, or your fan motor. There could also be an issue with your thermostat. 

The average lifespan of a furnace is 15 to 25 years. However, during that period, your system may require multiple repairs. If your furnace is not operating properly, schedule a consultation with an HVAC contractor in your area.
